A suitable case for my componets

ASRock Z77 Extreme4 Motherboard

Intel Core i5 3570K

Gigabyte GeForce GTX 670 Overclocked 2GB

Corsair CX-600 V3 Power Supply

What case would fit all this plus look cool?

The limiting factor will be your graphics card. Assuming that you have model GV-N670OC-2GD, you'll need a case that can handle a 11.2" long video card. Any ATX mid-tower case that can accommodate that graphics card will handle the rest of the components with ease.

As for "looking cool", that's a subjective question if there ever was one! If I had to pick one, I guess the Cooler Master Storm Scout 2 (model SGC-2100-GWN1) would meet the bill.
