MauveCloud :

Some advice I can give you in the meantime:
I don't recommend overclocking with a low-profile cooler. The Elite 120 you had before wouldn't fit a Hyper 212 evo, so you'd probably have to get a sealed-loop liquid cooler. Alternatively, you could get a BitFenix Prodigy, which as I understand can fit the 212 evo. If you don't need mini-itx and want the ATX board in your newer list, you could get a Cooler Master HAF 922.
