OK, put most of the stuff into this case for my new build... (still waiting on delivery of the actual power supply and Samsung 830 SSDs for the RAID-0 boot), and a few things to note:
Installing my video card was a pain with this case. I had to remove the whole tool-less fixture (3 screws) to install my GTX560 ti, since the geometry was all wrong to insert the card properly in the PCI-E slot while trying to slip it into the tool-less slot holder clips.
The USB 3.0 cable is not the best engineering

It loops around about 5 inches out the back, and the cable is stiff. I'm tempted to unplug it and forego the the single USB 3.0 port... they should have created a better connector at the external rear panel USB 3.0 port to plug in, allowing the cable to go in flatter.
The huge fan on top is awesome, but keep in mind, there is no protection for cables running underneath it, and care must be taken to route them properly out of the way of the fan blades.
The floppy bays were a tight fit for my memory card reader, specifically the guide tabs - I needed to pry them (very slightly) to get the reader to fit.
I can't say too much about cable management... my temporary power supply is an Antec 550W, and is not modular. Cables everywhere. My final PSU is an 850W Cooler Master Silent Pro Mark II - it's modular, so that should help. If you are one of those enthusiast who pay a lot of attention to detail, you can probably handle the cable management fine in this case.
I'm running an ASUS P8Z68-V Pro/GEN3 motherbord with an i7 2600k, cooled with a Corsair H70. The radiator is mounted to the case's rear chassis fan, which was reversed to bring air in over the radiator. My CPU at idle is room temperature (71degF) as is the motherboard chipset. Cooling is great in this system, even with the wire mess in it right now.
The drive bays have 4-pin Molexes and SATA cables dropping down through the case to connect. To really utilize them, make sure your motherboard has hot-swappable (AHCI) options for your SATA (mine does)
Overall, I'd rate this case about 8.5 out of 10 on my personal scale. It could have better cable management, but otherwise, it has everything I expect of a contemporary computer case. This is the best case I've owned so far.
One oddball note... anybody have any idea what the "Power Holder" is for??!??!?
