NASDAQ:  NSIT                                              FOR IMMEDIATE RELEASE
                                                        WEDNESDAY, JULY 17, 2002

                       INSIGHT ENTERPRISES, INC. ANNOUNCES
                     ANTICIPATED SECOND QUARTER 2002 RESULTS

TEMPE, ARIZONA - JULY 17, 2002 - INSIGHT ENTERPRISES, INC. (NASDAQ: NSIT) (the
"Company") today announced that it expects net sales for the second quarter of
2002 to be approximately $737 million compared to $505 million in the second
quarter of 2001. Second quarter diluted earnings per share are expected to be
between $0.26 and $0.29, compared to $0.26 in the same period last year. The
Company previously stated that it expected net sales and diluted earnings per
share to be between $720 million and $760 million and $0.31 and $0.35,
respectively. These results reflect three acquisitions made by the Company
during Q4 2001 and Q2 2002. The Company is a holding company with two operating
units, Insight Direct Worldwide, Inc. ("Insight") and Direct Alliance
Corporation.

The disappointing Q2 2002 results are due to the operating results experienced
by Insight's United Kingdom operations, which had operating losses in Q2 2002
compared to operating earnings in Q1 2002. It was not until the consolidation
process that it was determined that actual results were substantially lower than
expected. According to Timothy A. Crown, Chief Executive Officer, "Net sales in
the United Kingdom declined from $113 million in Q1 2002 to $89 million in Q2
2002, or 21%. The decline in net sales occurred primarily in the large
enterprise sector. Additionally, due to strong competitive pressures and reduced
demand, the gross profit percentage in the United Kingdom for Q2 2002 was lower
than expected."

Mr. Crown continued, "Effective today, both the president and chief operating
officer of Insight's United Kingdom operations have resigned and we have
replaced them with other executives from the Company who will operate the
business until permanent replacements are found."

Additional information will be provided when the Company reports its second
quarter results on July 25, 2002.
