I agree with the PSU recommend. What's your budget looking like for a PSU, you didn't list one (I'm SURE you didn't intent to use one that came with one of those cases...)? FSU makes good budget PSUs as well. Theres a sticky in the PSU section for quality PSUs. Pick one you can afford on that list. you only need ~400w tops.
