Current PC Build Recommendation

My friend was building a computer so we went through a bunch of components to figure out what he should make. Here is the current list of what I think makes a great mid priced PC ($1600ish). Its not far from my current PC newer CPU, GPU and more power.

CPU: Intel Core i7-2700K Sandy Bridge 3.5GHz (3.9GHz Turbo) 

Motherboard: ASUS P8Z68-V

Memory: CORSAIR Vengeance 16GB

Graphics: EVGA GeForce GTX 570 HD

OS/Software DriveIntel 510 Series 120GB SATA III

Data drives (buy 1 or 2): Western Digital Caviar Black 1TB

Power Supply: PC Power and Cooling Silencer 910W

DVD/blue ray cheapest one, whatever you need drive

Case... its kinda up to you on how you want it to look. This is the case I have, cheap and works fine.
