bigshootr8, maybe I'll just go with the 500w version instead of the 400w, it's only $10 more.
Pyree, the K isn't much more, and with all the fans in that case I will have(200mm in front, two 120mm in top, 120mm in rear) and the option for liquid cooling a little OC would be an option wouldn't it?
EDIT: As far as graphics go, I don't really go crazy about being able to run everything on the highest setting, just that it runs the games well, and they don't look like total crap
