Ladies and Gentlemen:
We have examined the Registration Statement on Form S-8 (the “Registration Statement”)
of Insight Enterprises, Inc., a Delaware corporation (the “Company”), filed with the
Securities and Exchange Commission (the “Commission”) pursuant to the Securities Act of
1933, as amended (the “Securities Act”), in connection with the registration by the Company
of 3,000,000 shares of the Company’s common stock, par value $0.01 per share (the
“Shares”), pursuant to the terms of the Amended Insight Enterprises, Inc. 2007 Omnibus Plan
(the “Plan”).
We have examined the originals, photostatic, or certified copies, of such records of the
Company and certificates of officers of the Company, public officials, and such other documents as
we have deemed relevant and necessary as the basis for the opinions set forth below. In our
examination, we have assumed the genuineness of all signatures, the legal capacity and competency
of all natural persons, the authenticity of all documents submitted to us as originals, and the
conformity to original documents of all documents submitted to us as copies.
Based upon the foregoing examination and in reliance thereon, and subject to the assumptions
stated and in reliance on statements of fact contained in the documents that we have examined, we
are of the opinion that the Shares, when issued in accordance with the terms of the Plan against
payment therefor, will be validly issued, fully paid and non-assessable.
We consent to the filing of this opinion as an exhibit to the Registration Statement, and we
further consent to the use of our name in appropriate sections of the Registration Statement and
the prospectus that forms a part thereof. In giving these consents, we do not thereby admit that
we are within the category of persons whose consent is required under Section 7 of the Securities
Act or the Rules and Regulations of the Commission.
Very truly yours,
/s/ Snell & Wilmer L.L.P.
