That system and I would be a mismatch. My risk-averse nature and only mild overclocks do not justify water cooling, and all those fans probably mean too much noise. A nice glow is one thing, but all the lights on that one would look out of place in my living room. I'd like to have a GTX460 in my rig (since I play Sacred 2, which uses PhysX), but I don't know that an i7/940 would be visibly faster in any of my games than my Q9450.
Fortunately, although I'd like to believe many of my comments are at least thoughtful, few qualify as witty, so I need not pheer winning this. I'm not sure what I would do if I won it, maybe sell off the case and w/c components for something quiet like an Antec P183 and rebuild it in that.
