That power supply is not very good I would go with a brand name reliable one.
Never skimp on the power supply.
Corsair,Coolermaster, Thermaltake or silverstone. Also that mouse is very cheap and the cord is really thin and won't last long. For a little more money i would get a better keyboard and mouse.
I agree with galeener. The thermaltake 750W PSU isn't overly expensive, and it's dangerous to gamble on a product that has such awful reviews (as has really everything from XtremeGear). If you're planning on overclocking, definitely get a higher quality fan as well.
Other than that, great looking PC. That case is badass!
