With a budget limit of, howz $1,191 suit ya ?
HAF-932 is outdated (No front USB 3 ports for example). The HAF-X is a fine case, to my mind only exceeded by the DF-85. I have built 6 boxes w/ the DF-85 (one w/ HAF-X) and the case grows on me more each time. best thing about it is the fact that it fits the CPX form factor PSU's which jonnyguru writes about the CP-850:

It is completely unmatched by any ATX unit on the market I can think of. You'd have to spend twice as much as this thing costs to find the next best thing, performance wise.
Scythe Mugen 2 is more than you need for Sandy Bridge....there are better coolers but putting them on SB CPU's won't get ya better OC's. It outdoes the Hyper 212 by 7C so the extra $10 is well worth it. Shin Etsu matches AS5's thermal properties but w/o the problematic 200 hours curing time that AS5 requires. The 560 (factory OC'd to 900MHz) comes very close to matching the 570.
