Thanks for looking, folks.

I have done some testing with and without the additional front fan ... I see a few degrees improvement with the second fan in. It's actually most noticeable on the top GPU ... it helps keep it cooler, which makes sense. The fans that came with it are quiet, but not very powerful. I'll be looking to put some better fans in, and just control them with the Kaze. It also comes with another 120mm fan to cool the chipset area ... but, I don't want another fan moving air (and noise) in the middle of the case - and I don't think it's necessary with the i7.

I've also got some San Ace fans I can hook up to the Noctua, should I need to go crazy.

I considered having holes cut in the top (it's an option ... I purchased from Performance PCs). BUT, my primary desire is a quiet system. While I do game on this, I also spend a lot of time doing my work applications, Photoshop, and just web browsing - so, I didn't want to put any additional holes in the case to generate more noise.

I'm only using the PC part time, so I can't water cool it. BUT, this case is big enough and is laid out well to make water cooling very easy in the future.
