2 HP OEM computers, but i didn't purchase either one.
first one from 2006 was a gift from my dad. came with a dual core athlon and 1gb of ram. it was actually a decent little machine but the integrated graphics really killed my gaming ambitions. motherboard died after 2 years, too. it would also constantly overheat before i figured out how to change thermal paste. still using the case, monitor, mouse, keyboard, HDD, and cd drive with my 2600k though lol
second one is my cousin's computer that his father purchased for him. an HP with a 2600 CPU(yes i7 2600) on a cheap h67(?) motherboard with 4gb ram and a 6450. that thing costs like $2000 because of all the "beats by Dr.Dre" stickers pasted all over.
