ive got an o'ced Q6600, 4 sticks of ram, an factory o'ced 4870, 2 hdds, a pair of CCFL tubes and 10 fans in my cabinet in all... (2 in the front, one at bottom, one at the sides, one at the back, 2 at the top and 3 fans on my TRUE 120), my cabby is a CM 690 and guess what, the VX450 doesnt break...
