I recently assembled my first system, which included a HAF922 and a Corsair TX750. Because this system is sitting on carpet, I figured I shouldn't aim the power supply at the bottom of the case, so I installed it upside down (the case provides mounting holes that allow for that). Right now I'm not overclocked at all and I'm using a pretty cheap tower heat sink on the CPU, but I have an H70 on the way and I plan on overclocking. I've also got a 5850 in the system.
Is having the power supply upside down going to be a problem? Should I find a way to get the PC off the carpet and install it the other way, or will it not be an issue? Should I put a side fan in to provide more cool air for the power supply to suck in?
