CONCORD, N.H. (AP) – A 45-year-old Hooksett man faces up to 10 years in prison after pleading guilty Tuesday to selling counterfeit computer parts to atomic power labs run by the federal government.

Officials say Mark Brunelle pleaded guilty to a federal charge of trafficking in counterfeit goods.

Prosecutors say his Bow-based company, Hardware 4 Less, advertised itself as a reseller of Compaq products and in 2002 sold $380,000 worth of computer memory kits to a California company.

Brunelle did not know that the company had been hired to upgrade supercomputers at the Knolls Atomic Power Laboratory in Syracuse, N.Y., and Bettis Atomic Power Laboratory in West Mifflin, Pa. Both facilities are run by the U.S. Department of Energy.

Prosecutors say Brunelle’s company collected the parts from various sources and assembled and packaged them to resemble Compaq equipment with phony labels, packing and warranty booklets.

Officials say that when questions arose about the authenticity of the parts, he sent a letter on bogus Compaq stationary that supposedly verified that the products were legitimate.

Compaq sued and got injunctions against Hardware 4 Less and other companies involved in selling the counterfeits and printing the phony documentation, according to court records.

Brunelle will be sentenced May 3.
