Unless you've already bought it I'd considering redo that setup.
X79 has limited support, no sleep, no speedstep etc..
Goinf Z77 with a 3770K which easily overclocks to 4.4Ghz++ will be cheaper and more compatible.
As for case and PSU, those don't matter in regards to hack compatibility.
I consider getting a GA-X79-UD5 with a i7 3930k.
Simply because SandyBridges overclock much better than IvyBridges, and I like the hexcore power of the 3930k. With a good cooling system, 4.7Ghz can be easily achieved as a 24/7 setup.
The H60 is not a really big cooling system, 4.4 could be pretty hard.
I heard of some people where sleep works (I don't care since my machine never goes to sleep), speedstep is unecessary anyway when OCing, and limited support? You still have 3 years of warranty.
