I don't know the specs just yet, but one of them is some sort of a celeron (same socket as p3 I'm guessing) and another one is some sort of P4 running around 1.6-1.7ghz. All come with towers. My dad picked them up at work cause they were thrown away since they were "defective". I tried the celeron one and it worked right away

Anyway I'm too drunk right now to mess with computers, so tomorrow I'll take a 256mb ddr stick from my current computer and plug it into the p4 to see if it works. My dad also brought a P4 mobo, in its box, but I had a look at it and although it smells pretty new, I saw one leaked capacitor :/
I'll be back with news tomorrow.
