Son, I remember the days... I had a white giant back in the day. 2.6ghz pentium 4, with 512mb ram, and a whopping 64mb graphics (I did chuck an nvidia fx5500 in it, but it did fuck all... Literally ate the computer alive. not enough power for it. It was still shit in the next computer)
It's always fun to try and play games on them. Quake 3 was like the only game I could play
