WOW!!! man this is looking nice and evil, evil.

keep up the good work mang!!

One thing I'd like to point out to you. Your GTX will only be sucking in the hot air from the radiator, which will result in your GTX getting very hot, which will also result in giving off a lot of heat in the case + the heat from the radiator, which will result in a hot case, which will result in hot hardware, which will result in high temps.

Science lesson for the day!!!!
JK lol, you should be fine, my only concern would be the video card, maybe try something else?

Edit:
Whoa, I just got a better idea!!! Get an Accelero S1 cooler and run it without a fan on it, the fans from the radiator will be cooling it!

Also, I'd consider a different video card? G92 maybe?

Edit 2:
OR
You could get an HD3870X2 and buy my waterblock for sale (see sig) and watercool it too!!!
I'm sure your rad will handle it.
