One of my friends agreed to have me build him a computer, and he really likes the idea of having something similar to those "FragBoxes", which I hope is a good thing, since i can then charge him more for one. Now obviously i would need a Radeon card in there, as well as a decent 2.5Ghz or faster processor. I really don't know too much about these SFF systems, and how the heat buildup and other things are, with them.
Essentially, I just need some suggestions on the setup for a stable gaming machine, in one of those SFF cases.
