I just got my system swapped into my HAF, and I must say my idle & load temps are literally night-and-day different! I made a lot of mods to it by drilling out the bottom HDD cage, taking out the top 230mm fan, top-mounting the PSU, and using the 4-in-3 CM HDD cage. I also removed the black metal filters from the front plate and those little side columns at an angle in the front. Except for the side and front 230mm fans, I used nothing but the CM r4 120mm Red LED fans (rated 90CFM @ ~22db). I also swapped the 4-in-3 stock fan for r4 Red and changed the orientation.
Fan Configuration: 230mm front fan as intake, 230mm side fan as exhaust, 120mm rear intake, 120mm top exhaust, 2x120mm intakes, and 120mm fan on the 4-in-3 as exhaust. Given the exhaust of my PSU, and 2 video cards, that leaves roughly 35-40 CFM of positive pressure, and the side fan as an exhaust with front low and rear upper intakes creates a vortex of air right above the MoBo. I won't mind dusting this thing out once or twice a month (standard procedure for me anyway). But, with this config. and the positive pressure, there's usually minimal dust build-up anyway. I had a similar config in my old Apevia case which had about 70% of the room this thing does, no fan filters, and the only real dust accumulation was in the HS fins of my Core Contact Freezer.
Moral of the story: This case is AWESOME! I will post pics later tonight after work if I get to it.
All I'd like to do now is swap the black side fan for another 230mm with the red LEDs. I'm also thinking about swapping the annoying as sin blue LED power and HDD indicator lights with something much more subtle...
Cable management was relatively painless as well...
