Hyper 212+ / Shythe Mugen 2
Umm... The Hyper 212+ is all good, but my second recommendation would have been the
Scythe Mugen 2
But in all seriousness though, the CM one is the one to go for mostly 'coz I find it easier to work with inside the case without the heft of the SM2 especially with multiple RAM sticks and PCIe cards, a RAID array, GPU connectors and stuff inside a mid sized cabinet.
