For gawd's sake... GET A DECENT CASE & POWER SUPPLY COMBO. That PSU will put out 550 watts when hell freezes over. This case/PSU combo is a decent one, and you won't have to buy a new power supply when the other one fries in a year:

Believe me. I've been there with a el cheapo case and power supply combo with a "600W" power supply from TigerDirect.com. And believe me when I say that it will struggle to power that graphics card and CPU without crashing. Please, don't be conned into getting some low quality P.O.S. power supply.
As for the mobo/CPU combo, your looking good. And keep in mind that you wanna get DDR RAM. It usually is expensive,
but this is a darn good deal.
