I have an antec 900 and love both the looks and the airflow. There are cheaper cases with similar airflow if you are on a budget, but I think the 900 looks really nice also (its not just a boring box shape) if you have the money.
It looks to me like the antec's front fans will blow cool air straight into the back grill of the vaporx GPU which should provide excellent cooling. You wont be able to put a drive in the drive bay on the same level as your graphics card (with 8 other drive bats, who cares). I also moved the front fans up so the top one blows cool air directly over the RAM and my drives are at the bottom.
The main thing I wish I had done is got a modular PSU so I didnt have a wad of ugly cables lying in the bottom of my case for everyone to see.
