Case is awesome looking on the outside, but "no finger hurting" really is not a good substitute for the specs you need to make a decision on the PSU. First it says 250W, then label 800W, without any mention of the make or model. There are lots of bad power supply makers out there, and this is almost certainly one of them. You'll need 500 to 600 Watts to be comfortable.
I realize this is probably more than you wanted to spend. If you wanted to get a lower wattage chip, say this AMD Athlon II X3 450 for $80, and did not plan on overclocking, then I would be tempted to buy the Newegg shellshocker deal that is available for the next 5 hours:
