I have this case and was able to stick a 120mm fan in the lower chamber. It took some work though. A 25mm thick fan is just a little too thick to fit between the front of the case and the HDD rack. So I took out the dremel and sanded down one side of the fan a little. Now it fits tightly...
I'm going to wait and see what [H] has to say before I make a decision to replace my 8800 GTS 640MB. Maybe it'll just be until the next generation NVIDIA parts come next year.
Oh well, I was pulling for ATI/AMD to come out with something (competing products make for better prices for us)...
