Looks like a very well thought out rig. Love the case, very stylish. Not knowing your budget it is hard to critique. However, I like how you have chosen 4GB of RAM and the 6850. 4GB is plenty, 8GB is overkill for many average users; and the 6850 pumps-out great FPS even with 4xAA. Just to note, have you seen the new BitFenix Shinobi
case? Very much like yours and comes in cheap.
