I would go the haf X out of the 2 but i have som other considerations.
RV03 is out it has usb 3
Thermaltake chaser mk I relitivly unproven but it has good cooling and from what i can see is the only case with a usb 3 internal header AND 2 usb 3 ports on the front. it also fits big graphics cards
Antec 1200 v3 it has great cooling you know it will be a great case and it has one usb 3 on the front via internal I/O
if you went either the haf x or the Raven you would rout the usb 3 cables to the back.
