@ the OP. That case is a total hose job and then some, that psu would never be recommended on here, the RAM is great if you plan on using it for a hair comb otherwise it's going to screw you with an after market cpu h/s seeing how it has those tall cake cutter heat spreaders, and the 570 is a power hog vs performance that sucks at over clocking.
This MSI 560 ti 448 core down below when over clocked comes close to running on par with a stock gtx 580. 560 series cards are on a newer die, run cooler, and use a lot less juice.
@ the OP...check this one out.
