It really is a nice case, I'm glad I decided to pay a wee bit extra to get it over the HAF-XM.
I'm going for a quiet build as well, my current plan is to gut all but two of the HDD bays and all but one of the Opticals(since I've decided to go with one 840 pro SSD and a 2TB green drive rather than two SSDs and my old noisy 1TB, and I only need one bay on the front for my DVD/RW), then take the 200mm top fan that comes with the case and mount it up-front above the forward 230mm. Those two and the side 200mm will all be set as intakes, running on a Bitfenix molex-to-3-3pin 7v undervolt cable. I managed to get my hands on some industrial-grade metallic two-part epoxy, which along with a couple of screws will let me put a wee extra metal bar in the top to create mounting holes for a Kraken X60, and I'll be running a Red Mod on my GPU with a Kuhler 620 using dwood's bracket and some copper VRM/VRAM heatsinks, both of those will be getting Noctua fans in pull-only set to exhaust. I also grabbed some silicon anti-vibration washers for all the screws, and a few sheets of noise-dampening foam; it won't really stop "noise" from getting out of the case because of all the fans, but it will deaden the currently very echo'y case(which sounds like you're ratting a tin full of change when the mechanical HDD is in use, inevitable given the sheer size of the interior). I think that setup will still give me enough intake airflow to create positive pressure inside the case to help avoid dust buildup, but I'm considering adding those medical-mesh dust filters to be on the safe side - depends how much they reduce airflow(I can't find a solid answer anywhere online :/ ).
If it performs as expected, I should be able to get a whisper-quiet rig even under full load, and still get low temps.
