Gaming PC primarily, quite liking it.
Do plan on going dual monitor in the future though. I prefer the aspect ratio of the 24" screens to the 27", but it leaves me with a little less screen real estate. Do not have the extra 780 in this PC at the moment, thinking about adding it when I go dual monitor.
Currently I've put the 780 in my downstairs PC so I can move it and stick an old 280 in there, you guys think this will be needed?
Quite happy with the Kraken too, can run some pretty sick volts through the 4770k without issues even at high load:
*EDIT: Uploaded a few pictures of the build with the peripherals as people requested, and screenshot with GPU-Z/CPU-Z for OC's and HW spec.
