honestly, I would stay away from Compaqs. They are dirt cheap, but often a bitch to deal with. I got a Amd 533 or something, for my mother a little whiel back, with 128MB ram, 8MB video card, Cd-RW etc, for 450 dollars.... it works okay, but I curse the day that I need to try to upgrade it..
-AMD's are not for the faint of heart... Intels? those are for newbies
