Not really. The X6 isn't a great CPU for gaming, and you can do better for other tasks. The Coolermaster PSU is a POS. The Crosshair 4 is a waste of money. Liquid cooling is also pretty wasteful, as it's expensive and doesn't really do much that an air cooling solution can't.
I highly recommend you give us a budget and use. Basically, you should follow the guidelines from the link in my signature.
Here's an example of a build that would perform just as well, yet be a hell of a lot cheaper:
CPU/GPU: X4 955 and HD 5870
Mobo/PSU: Gigabyte GA-790XTA-UD4 and Corsair 750HX Modular
$215 after rebates
RAM: G.Skill Eco 2x2 GB 1600 mhz CAS Latency 7
HDD: Samsung Spinpoint F3 1 TB
Case/Optical: Coolermaster 690 and cheap SATA DVD burner
HSF: Coolermaster Hyper 212 Plus
