title basically gives you a baseline on what I'm trying to figure out. Currently, I'm in the process of making my new pc rig. I've ordered an MSI Z97 Gaming 7 MOBO, an Intel i5-4690k processor, also a gtx 960 from my old rig plus 8gb ram and 550W PSU. I'm fitting it all into a "COUGAR Challenger Black Steel ATX Computer Case with 12cm COUGAR TURBINE HYPER-SPIN Bearing Silent Fans and 20cm LED Fan" (as portrayed on newegg site). Now, my question is will an H110i Corsair 280mm cpu watercooler be able to be mounted properly with this setup? What limitations will I have to watch for and also, what would be the recommended wattage for a PSU as I fear this might not be enough to power my system?
