I currently have the CM Storm Stryker and would like to move down to a mid-tower. Right now the Corsair Carbide Air 540 is looking pretty good to me. Major concerns: at least 1 5.25 bay, space for Kraken X60, space and airflow for 7990.
ASUS maximus VI Hero
Kraken X60 Liquid Cooler
AMD Radeon HD 7990
16GB Gskill Sniper RAM 2400 Mhz
(2x) Seagate Barracuda 2Tb in RAID 1
(2x) Kingston v300 120Gb SSD's in RAID 0
(1x) Intel 520 300Gb SSD
EVGA SuperNova 750W PSU
LG 24x DVDRW
The Air 540 is a nice case but also collects a lot of dust. Get the Fractal Design Define R4 http://www.amazon.com/gp/product/B008HD3E6Y. The R4 is a pretty amazing case with noise dampening padding, built in air filters, and support for 240/280mm radiators.
I've go two Fractal cases, the Define Mini and the Node 304 and I will say that Fractal cases are nice to work with and very quiet.
