With all cases, airflow can easily be attained. It isn't a closed box/system where air is recycled within the system with no transfer of energy. Fans from the front of the case, is pushed. There's vents on the front and the bottom of the front panel. The way the HD's are facing is actually a complement to the front panel's style because if "lack of air" was truly an issue, having side facing HD's will obstruct airflow even more.
I've had my Shinobi window for about 6 months now (When I started, I got one right away). I haven't seen dust build ups inside (It has been sitting on the ground for 5 months). Maybe it's me, but I added red carbon fibre to my side panels, so I don't mind the grills at all.
Our fan controller
s launch this week, and even with a fan controller + case combo, you'll still have enough for fans, and then some... (the controllers have LED toggle switches if you're using our LED fans) if your budget was $100.
I've been following your posts, and you've spent a whole deal of time. I applaud you for being so nit picky. It's how awesome builds come together.

Unlike the time I went shopping for a car... No test drives, no research.. Just walk to the Toyota dealership, and say "I want that Scion XB." *Sign papers* Drive.
