The Best PCs You Can Build for $300, $600, and $1200
It's pretty amazing what you can build for less than $300 these days. The $300 box in particular would make a fantastic XBMC box, provided the PS is relatively quiet.
SharkyExtreme used to do these "Budget, Mid-Level, Extreme Budget Gaming Rig" rundowns back in the day. I remember when the 2.53GHz P4 was the newest thing. Chip was like $800.
Awesome progress. If my PS3 ever takes a shit I'll probably just build a $300 home media server.
