If you have carpet the Blackhawk would be nice considering how raised it is.
However I have the HAF 922 which is awesome quality so I know those guys (CoolerMaster) can make some pretty nice cases.
I do have carpet but i dont keep my case on the floor!
I have it on my BIG DESK next to my monitors and speakers!
I know CM HAF X is great but i wanted to have something else for a change bcz i am really picky about CASES and since i got really dissapointed in my RAVEN RV01 i dont really what to do any more!
