The coolermaster case is an ugly but very practical case. This rig preforms well for gaming. Payday 2, easy. CS:GO, no problem. I have not tested it any demanding games yet but I expect good results. Preforms well for multitasking.
EDIT: It runs Bioshock infinite and Farcry 4 on ultra, with no problems. Shadow of Mordor can only run on high texture settings in large areas without lag when moving the camera view.
