It is going to consist of:
MSI Z68A-GD55 motherboard
Intel i52500k cpu
Noctua D14 cooler
Corsair CML8GX3M2A1600C9 8GB (2x4GB) Vengeance DDR3 (Low profile because of the size of the cooler)
Corsair TX-750 V2 Power Supply
& 2 of these ASUS Radeon HD6950 DirectCU II 1GB crossfire
I need recommendations on good PC cases that will be able to fit all of this hardware inside .
