Just got my new Mac Pro and I'm rearranging my desk/office to accomodate this monster tower. I think I know the optimal answer to this question, but, where is the best place to position this tower - so that I can maximize desk space and not attract too many dust bunnies. My office is carpeted and the last time I opened up my old PC tower loacated on the floor, it looked like a lanscape from Mars, with dust everywhere. I'd like to put the Mac Pro on the floor and I could raise it 5 or 6 inches, if needed, to hopefully avoid some dust. I'm just leary as this unit has so much venting and I'm guessing considerable cross ventilation. Also, if I did put the system on the floor, what is the method of internal cleaning - an anti-static vacuum? Any advice would be appreciated from a pc-switcher.
