RIP and decon give good advice on the HDD. You probably want a 7200 rpm model, and the larger (1 TB +) models give more value. The HAF 922 doesn't have good cable management, so a modular PSU will improve cooling. The PNY TTX 570 is a reference model, and has inferior cooling. The MSI ans ASUS & Gigabyte GTX 570 models with multiple fans will run cooler.
