That certainly would get the air moving!
I have done the top window mod using a smaller window because I opted for heavy duty case handles instead of a 2 or 3 fan window.
As bigfish suggested, you would probably want to go with 120mm fans if you could, to keep the noise down and the cfms up. I had to find a special retailer to provide me with the exact window in the dimensions I was looking for, so it was a trial.
I would say find a case you truely like, and mod it from the ground up. I think you'll be a lot happier with it.
But hey, you're right - that is a nice case! Prebuilts are ok, but modding - it's the only way!
