Just thought i'd let you guys know that if anyone plans on getting the antec 900 (can't say for the 1200) to look forward to alot of maintenance. This thing gets very, very dusty. Wiping it down once a week is a usual for me now, and as far as the inside, I have to dust it off a bit every 1 - 2 weeks, so long as I keep on it. I made the big mistake of not keeping ontop of my cleaning schedule for a while and let me tell you, big mistake. My entire PSU/GPU were completely filled with dust\dust bunnies. I had to take my PSU just to give it a good clean and wiping down the blades on the fan for my GPU wasn't fun either. Something to keep in mind if you have, or plan on getting this case.
