I'm just going to put it in the top front fanbay. I will have to have 2 fans in front of the radiator and 1 behind. If it causes too much noise i will just gut the middle one. But i will most definately keep an eye on CPU temps for awhile.
It's mocked up in place right now and seems like it's going to fit pretty well there. Just have to see how the 2 fans in front are going to work.
