	1.Basis of Presentation
	We have prepared the interim financial statements included in this Form 10-Q without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).  We have condensed or omitted certain information and footnote disclosures, normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, pursuant to such rules and regulations.  You should read these financial statements in conjunction with the financial statements and related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013.
	The financial statements presented herein as of June 30, 2014, and for the three months and six months ended June 30, 2014 and 2013, reflect, in the opinion of management, all adjustments (which consist only of normal, recurring adjustments) necessary for a fair presentation of the financial position and the results of operations and cash flows for the periods presented. Management makes estimates and assumptions affecting the amounts of assets, liabilities, revenues and expenses we report, and our disclosure of contingent assets and liabilities at the date of the financial statements.  The results of the interim periods are not necessarily indicative of the results for the full year.  Accordingly, you should read these condensed financial statements in conjunction with the audited financial statements and the related notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013.  Actual results could differ materially from these estimates and assumptions.
	Recently Issued Accounting Standards
	In June 2014, the FASB issued Accounting Standards Update 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period (“ASU 2014-12”), which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. Thus, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2015. Entities can apply the amendment either a) prospectively to all awards granted or modified after the effective date or b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. We currently do not anticipate the adoption of this standard will have a material impact on our condensed consolidated financial statements.
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU No. 2014-09”). The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. This ASU is intended to provide a more robust framework for addressing revenue issues; improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and provide more useful information to users of financial statements through improved revenue disclosure requirements. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2016. We are currently determining our implementation approach and assessing the impact on our consolidated financial statements.
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (‘‘ASU No. 2013-11’’). ASU No. 2013-11 provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU No. 2013-11 did not have a significant impact on our consolidated financial statements.

	Effective January 1, 2014 and pursuant to Deferred Stock Unit (“DSU”) Master Agreements, each member of the board of directors may elect to receive DSUs with a fair value equivalent to a percentage of each quarterly installment of the annual cash retainer for non-employee directors to which that member would otherwise be entitled for service as a Datalink director during 2014. In addition, each member of the board of directors may elect to receive a DSU award equal to a percentage of the award of shares of Restricted Stock to which that member would otherwise have been entitled as the equity component of the 2014 annual retainer. The DSUs and DSU awards vest and become non-forfeitable on each of June 30, 2014, September 30, 2014, December 31, 2014 and March 31, 2015, provided the board member remains in service with us. We will issue one share in payment and settlement of each vested DSU subject to the Master DSU Agreement following a termination of that board member’s service with us.
	We recognized expense of $96,000 during each of the three month periods ended June 30, 2014 and 2013 related to awards of 9,625 shares and 9,000 shares, respectively, of fully vested common stock to members of our Board of Directors.  Of the 9,625 shares of fully vested stock awarded to member of our Board of Directors during the three months ended June 30, 2014, 5,125 shares were DSUs. During the six months ended June 30, 2014 and 2013, we recognized expense of $228,000 and $204,000, respectively, related to awards of 19,074 shares and 18,000 shares, respectively, of fully vested common stock to members of our Board of Directors.  Of the 19,074 shares of fully vested stock awarded to members of our Board of Directors during the six months ended June 30, 2014, 5,574 shares were DSUs.

	4.Income Taxes
	We base the provision for income taxes upon estimated annual effective tax rates in the tax jurisdictions in which we operate.  For the three months ended June 30, 2014 and 2013, our effective tax rate was 40.3% and 41.0%, respectively.  For the first six months of 2014 and 2013, our effective tax rate was 40.1% and 41.0%, respectively.  The decrease in our tax rate for the three and six months ended June 30, 2014 as compared to the same periods in 2013 is mainly due to the effect of federal graduated tax rates on our estimated annual taxable income. Additionally, we recognized benefits from approximately $14,000 of discrete item adjustments during the six months ended June 30, 2014. These adjustments decreased our effective tax rate to 40.1% for the six months ended June 30, 2014. We did not recognize any such benefits from discrete item adjustments during the three months ended June 30, 2014 or during the three and six months ended June 30, 2013.  We expect our annual effective tax rate for 2014 to be 40.2%.
	As part of the process of preparing financial statements, we estimate federal and state income taxes. Management estimates the actual current tax exposure together with assessing temporary differences resulting from different treatment for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which we include within our balance sheet. Management must then assess the likelihood that we will utilize deferred tax assets to offset future taxable income during the periods in which we may deduct these temporary differences.  For the three and six months ended June 30, 2014, we recorded income tax expense of $2.4 million and $2.6 million, respectively, with an effective tax rate of 40.3% and 40.1%, respectively.
	We assess our uncertain tax positions for tax years that are still open for examination.  As of June 30, 2014 and 2013, we had no unrecognized tax benefits which would affect our effective tax rate if recognized.
	We classify interest and penalties arising from the underpayment of income taxes in the statement of operations under general and administrative expenses. As of June 30, 2014 and 2013, we had no accrued interest or penalties related to uncertain tax positions. The tax years 2008-2012 remain open to examination by both the Federal government and by other major income taxing jurisdictions to which we are subject.
	Our ability to utilize a portion of our net operating loss carryforwards to offset future taxable income is subject to certain limitations under Section 382 of the Internal Revenue Code due to changes in our equity ownership.  We do not believe that an ownership change under Section 382 has occurred, and therefore, no such limitations exist.

	On October 4, 2012, we purchased substantially all of the assets and liabilities of Strategic Technologies, Inc. (‘‘StraTech’’) from StraTech and Midas Medici Group Holdings, Inc. (‘‘Midas,’’ parent company of StraTech and, together with StraTech, the ‘‘Sellers’’). StraTech is an IT services and solutions firm that shares our focus on optimizing enterprise data centers and IT infrastructure through a common product and services portfolio designed to help customers increase business agility. We purchased StraTech for a purchase price of approximately $11.9 million, comprised of a cash payment of approximately $13.2 million, which was offset by a receivable due from the Sellers of approximately $3.3 million, resulting from the preliminary tangible net asset adjustment as defined by the asset purchase agreement. In addition, we issued 269,783 shares of our common stock with a value of approximately $2.0 million. Of those shares, 242,805 shares were deposited in an escrow account as security for certain indemnification obligations of the Sellers.
	Pursuant to the asset purchase agreement, the Sellers were obligated to pay us an amount equal to the difference between the actual tangible net assets on the closing date and the Sellers’ good faith estimated net tangible assets as set forth in the asset purchase agreement. We initially recorded a receivable due from the Sellers of approximately $4.2 million related to this payment at the acquisition date. The Sellers provided us with a ‘‘Notice of Disagreement,’’ which stated that they disputed the amount owed to us in connection with this reconciliation payment. The asset purchase agreement contained an arbitration provision for disputes over the value of tangible net assets. During the measurement period (up to one year from the acquisition date), the final tangible net asset adjustment was agreed to and the net effect was a decrease in the receivable due from the Sellers of $936,000 and an increase in the purchase price for the same amount as reflected above.
	In January 2014, we reached a settlement agreement with the former owners of StraTech regarding the disputed amount owed to us in connection with the reconciliation payment mentioned above. Under the terms of the agreement, the former owners of StraTech agreed to release the entire 242,805 shares of Datalink common stock that were being held in escrow in exchange for a payment of $100,000 and the release of certain other claims. As of December 31, 2013, the remaining $3.3 million receivable due from the Sellers was deemed to be uncollectible and written down to the estimated realizable value, which was determined to be the fair value of the shares in escrow on December 31, 2013. The remaining receivable of $2,647,000 was reclassified from accounts receivable to equity within the December 31, 2013 balance sheet. Based on the value of our common stock on the date of the settlement agreement in January 2014, we recorded a gain before tax of approximately $876,000 during the six months ended June 30, 2014 as a result of the increase in our stock price from December 31, 2013 to the date we repossessed the shares in escrow.

	6.Goodwill and Finite-Lived Intangible Assets
	We assess the carrying amount of our goodwill for potential impairment annually or more frequently if events or a change in circumstances indicate that impairment may have occurred.  We perform an impairment test for finite-lived assets, such as intangible assets, and other long-lived assets, such as fixed assets, whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable.  Circumstances that could represent triggering events and therefore require an interim impairment test of goodwill or evaluation of our finite-lived intangible assets or other long-lived assets include the following:  loss of key personnel, unanticipated competition, higher or earlier than expected customer attrition, deterioration of operating performance, significant adverse industry conditions, economic or regulatory changes or a significant decline in market capitalization.
	We have only one operating and reporting unit that earns revenues, incurs expenses and makes available discrete financial information for review by our chief operations decision maker.  Accordingly, we complete our goodwill impairment testing on this single reporting unit.
	In conducting the annual impairment test of our goodwill, qualitative factors are first examined to determine whether the existence of events, or circumstances, indicate that it is more likely than not that the fair value of a reporting unit is less than its carrying amount.  If it is determined that it is more likely than not that the fair value of the reporting unit is less than its carrying amount, a two-step impairment test is applied.  The first step of the goodwill impairment test, used to identify potential impairment, compares the fair value of our market capitalization with the carrying value of our net assets. If our total market capitalization is at or below the carrying value of our net assets, we perform the second step of the goodwill impairment test to measure the amount of impairment loss we record, if any.  We consider goodwill impairment test estimates critical due to the amount of goodwill recorded on our balance sheet and the judgment required in determining fair value amounts.
	Goodwill was $37.8 million as of each of June 30, 2014 and December 31, 2013.  We conducted our annual goodwill impairment test as of December 31, 2013, our last measurement date.  Based on this analysis, we determined that there was no impairment to goodwill.  We will continue to monitor conditions and changes that could indicate impairment of our recorded goodwill.
	At each of June 30, 2014 and December 31, 2013, we determined that no triggering events had occurred during the quarter and our finite-lived assets and long-lived assets were not impaired.
	Identified intangible assets are summarized as follows:

	Our short-term investments consist of commercial paper, corporate bonds and interest-bearing CDs. We categorize these investments as trading securities and record them at fair value. We classify investments with maturities of 90 days or less from the date of purchase as cash equivalents; investments with maturities of greater than 90 days from the date or purchase but less than one year generally as short-term investments; and investments with maturities of greater than one year from the date of purchase generally as long-term investments.

	8.Fair Value Measurements
	Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.  In determining fair value for assets and liabilities required or permitted to be recorded at fair value, we consider the principal or most advantageous market in which it would transact and the assumptions that market participants would use when pricing the asset or liability.  We apply fair value measurements for both financial and nonfinancial assets and liabilities.  We have no nonfinancial assets or liabilities that require measurement at fair value on a recurring basis as of June 30, 2014.
	The fair value of our financial instruments, including cash and cash equivalents, short-term investments, accounts receivable, accounts payable, line of credit and accrued expenses, approximate cost because of their short maturities.
	We use the three-level fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair values.  The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements).  The three levels of the fair value hierarchy are described below:
		·		Level 1 — Unadjusted quoted prices available in active markets for the identical assets or liabilities at the measurement date.
		·		Level 2 — Significant other observable inputs available at the measurement date, other than quoted prices included in Level 1, either directly or indirectly.
		·		Level 3 — Significant unobservable inputs that we cannot corroborate by observable market data and thus reflect the use of significant management judgment.  We generally determine these values using pricing models based on assumptions our management believes other market participants would make.
	The fair value hierarchy requires the use of observable market data when available.  In instances in which the inputs used to measure fair value fall into different levels of the fair value hierarchy, we determine the fair value measurement based on the lowest level input that is significant to the fair value measurement in its entirety.  Our assessment of the significance of a particular item to the fair value measurement in its entirety requires judgment, including the consideration of inputs specific to the asset or liability.  The following table sets forth, by level within the fair value hierarchy, the accounting of our financial assets and/or liabilities at fair value on a recurring basis as of June 30, 2014 and December 31, 2013 according to the valuation techniques we used to determine their fair value(s).

	We occasionally enter into sales-type lease agreements with our customers resulting from the sale of certain products. Our lease receivables are recorded at cost within the accounts receivable and long-term lease receivables balances on our balance sheet and are due in installments over the lives of the leases. Cash received and applied against the receivable balance is recorded within changes in operating assets and liabilities in the net cash provided by operating activities section of the statement of cash flows.  Finance income is derived over the term of the sales-type lease arrangement as the unearned income on financed sales-type leases is earned. Unearned income is amortized over the life of the lease using the interest method.  The present value of net investment in sales-type lease receivables of $3.9 million and $1.3 million at June 30, 2014 and December 31, 2013, respectively, is reflected net of unearned income of $381,000 and $57,000 at June 30, 2014 and December 31, 2013, respectively. As of June 30, 2014, scheduled maturities of minimum lease payments receivable were as follows for the fiscal years ended December 31:

	10.Line of Credit
	On July 17, 2013, we entered into a Credit Agreement with Castle Pines Capital LLC (“CPC”), an affiliate of Wells Fargo Bank, National Association (“Wells Fargo”).  The Credit Agreement provides for a channel finance facility (“Channel Finance Facility”) and a revolving facility (“Revolving Facility” and, together with the Channel Finance Facility, “Combined Facility”) in a maximum combined aggregate amount of $40 million.  Borrowing under the Revolving Facility cannot exceed the lesser of (i) $40 million minus the amount outstanding under the Channel Finance Facility or (ii) a borrowing base consisting of 85% of certain eligible accounts and 100% of channel financed inventory, subject to CPC’s ability to impose reserves in the future.  The Channel Finance Facility will finance certain purchases of inventory by us from vendors approved by CPC and the Revolving Facility may be used for working capital purposes and permitted acquisitions.
	The amounts outstanding under the Revolving Facility will bear interest at a per annum rate of 2.0% above Wells Fargo’s one-month LIBOR rate (approximately 0.16% at June 30, 2014).  Advances under the Channel Finance Facility will not bear interest so long as they are paid by the applicable payment due date and advances that remain outstanding after the applicable payment due date will bear interest at a per annum rate of LIBOR plus 4%.  We are obligated to pay quarterly to CPC an unused commitment fee equal to 0.50% per annum on the average daily unused amount of the Combined Facility, with usage including the sum of any advances under either the Channel Finance Facility or the Revolving Facility.  The Combined Facility and certain bank product obligations owed to Wells Fargo or its affiliates are secured by substantially all of our personal property. The Credit Agreement terminates on July 17, 2016 and we will be obligated to pay certain prepayment fees if the Credit Agreement is terminated prior to that date.
	The Credit Agreement contains customary representations, warranties, covenants and events of default, including but not limited to, covenants restricting our ability to (i) grant liens on our assets, (ii) make certain fundamental changes, including merging or consolidating with another entity or making any material change in the nature of our business, (iii) make certain dividends or distributions, (iv) make certain loans or investments, (v) guarantee or become liable in any way on certain liabilities or obligations of any other person or entity, or (vi) incur certain indebtedness. The Prior Credit Agreement (as defined below) included similar restrictions.
	The Credit Agreement contains certain covenants regarding our financial performance, including (i) a minimum tangible net worth of at least $20 million, (ii) a maximum funded debt to EBITDA of no more than 3.00 to 1.00, and (iii) a minimum quarterly net income of at least $250,000.
	Of the $40 million maximum borrowing amount available under the combined Channel Finance Facility and Revolving Facility, we had outstanding advances of $17.0 million and $20.0 million on the Channel Finance Facility at June 30, 2014 and December 31, 2013, respectively, related to the purchase of inventory from a vendor.

	Recently Issued Accounting Standards
	In June 2014, the FASB issued Accounting Standards Update 2014-12, Compensation - Stock Compensation (Topic 718): Accounting for Share-Based Payments When the Terms of an Award Provide that a Performance Target Could be Achieved after the Requisite Service Period (“ASU 2014-12”), which requires that a performance target that affects vesting, and that could be achieved after the requisite service period, be treated as a performance condition. Thus, the performance target should not be reflected in estimating the grant date fair value of the award. This update further clarifies that compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2015. Entities can apply the amendment either a) prospectively to all awards granted or modified after the effective date or b) retrospectively to all awards with performance targets that are outstanding as of the beginning of the earliest annual period presented in the financial statements and to all new or modified awards thereafter. We currently do not anticipate the adoption of this standard will have a material impact on our condensed consolidated financial statements.
	In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (“ASU No. 2014-09”). The standard outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance. This ASU is intended to provide a more robust framework for addressing revenue issues; improve comparability of revenue recognition practices across entities, industries, jurisdictions and capital markets; and provide more useful information to users of financial statements through improved revenue disclosure requirements. The provisions of this ASU are effective for interim and annual periods beginning after December 15, 2016. We are currently determining our implementation approach and assessing the impact on our consolidated financial statements.
	In July 2013, the FASB issued Accounting Standards Update No. 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (‘‘ASU No. 2013-11’’). ASU No. 2013-11 provides guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. ASU No. 2013-11 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of ASU No. 2013-11 did not have a significant impact on our consolidated financial statements.
