BitFenix Colossus - Corsair H100i fitting!

Hey guys!

I'll very soon be getting myself a Corsair H100i installed into BitFenix Colossus case.... anyone possibly have any experience with this combination at all??

I've seen some out there top-mounting the rad, but I'm feeling a little sketchy about it, due to the front USB3.0 PCB possibly being in the way (might remove it, so I can fit the rad and possibly just buy the BitFenix 2-port USB3.0 5.25 bay to compensate). Or maybe even take the risk of getting the BitFenix Colossus Window Panel and mounting the rad onto that?? (Pull configuration) (spontaneous thought, could be rather stupid/retarded thought.... spontaneous nonetheless!)

Also would this configuration (top mount) be good for overclocking if used in a Push configuration?
