Btw, I tried to remove some of the dust screen... but that stuff seem to be glued to the door, and would be very hard to remove. I'm concerned about the fan reversal procedure.... I've just never seen computer hardware that blow air into the system, all the PCs, servers and storage systems I work with all pull hot air out.

Yes, but the air has to get into the box somewhere, right? :)

All kidding aside, cooling a heterogeneous combination of components is a complex affair, and mixes of push and pull fans are used by a lot of hardware devices.

The dust filter is a nice feature, but dust build up is less of a source of problems to me than heat, and loss of the intake dust filtering is a smaller matter to me than loss of power supply (or especially drives!).

BTK* - Maybe the next generation of hardware should have a heavier duty fan (or combination of fans) that run/runs at a quiet speed all of the time. Once a month, it activates a blow-it-out-the-rear** mode and spins up to 10,000rpm to dislodge the dust. Add a speaker so that it can play cough-cough.mp3 and it might even reduce the number of smokers worldwide by a slight amount.

** maybe a poor choice of phrasing?
