My two favorite "gamer" cases are the Antec DF-85 and the HAF-X in that order. The 1200 V3 is nice if ya don't want something styled so aggressively. Neither Antec however fits your "optional" E-ATX criteria. I have added USB3 front port as a requirement
The DF, like the 1200, has built in fan controls knobs (vari-speed front / 3 speed back) and the more "secure" feeling when assembling .... . The filters on the 1200 take a while to take out and clean, if the DF it takes seconds. I don't like the weak feel of the "tool less" features of the HAF whicxh can sometimes be frustrating to line up. Then again the "security feature" which allows locking of trhe 5.25 bays can be annoying when accessing tyen drive frequently.
About 3 outta the 4 peeps I build for choose the DF. Best thing about the DF / 1200 however is that they fit CPX form factor PSU's, the advantages of which are well described in the "Conclusions" paragraph here:

Not to mention jonnyguru describes it this way:
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.
