Ladies and Gentlemen:

          We are acting as special counsel for Dunn Computer Corporation, a 
Virginia corporation (the "Company"), in connection with the preparation and 
filing by the Company of a Registration Statement on Form S-1, Registration 
No. 333-47631 (the "Registration Statement"), under the Securities Act of 
1933, as amended, with respect to the registration of (i) 3,250,000 shares 
of Common Stock, par value $0.001 per share, of the Company (the "Offering 
Shares") and (ii) up to 487,500 shares of Common Stock, par value $0.001 per 
share, of the Company (the "Over-Allotment Shares") that may be sold pursuant 
to an over-allotment option granted in the Underwriting Agreement (defined 
below) (of which Over-Allotment Shares up to 243,750 shares may be sold by 
the Company and up to 243,750 shares may be sold by certain Selling 
Stockholders).  The Offering Shares and the Over-Allotment Shares, if any, 
that will be sold pursuant to the Underwriting Agreement (the "Underwriting 
Agreement") between the Company and Ferris, Baker Watts, Incorporated and 
Gerard Klauer Mattison & Co., Inc. are herein collectively referred to as the 
"Shares".

          We have examined such documents, records, and matters of law as we 
have deemed necessary for purposes of this opinion. Based upon and subject to 
the foregoing, we are of the opinion that the Shares are duly authorized and, 
when issued and delivered by the Company or sold by the Selling Stockholders 
to the Underwriters pursuant to the Underwriting Agreement against payment of 
the consideration therefor as provided therein, will be validly issued, fully 
paid, and nonassessable.

          We hereby consent to the filing of this opinion as Exhibit 5.1 to 
Registration Statement and to the reference to us under the caption "Legal 
Matters" in the Prospectus constituting a part of such Registration Statement.


                                   Very truly yours,


                                   /s/ Jones, Day, Reavis & Pogue
