Well, I think it's a standard ATX PSU.

Sorry, I got in a hurry there. What I mean to say here is that I think the case will fit a standard ATX PSU, from looking at the picture of the back. The PSU Obsidian linked is a great buy if your case fits it.

8800gts is an older card and not such a good buy any more. Better would be a 4850:
