But, If I am not wrong, the Corsair Carbide Series 500R case only supports mobo up to ATX form factor. since the ASUS Maximus IV Extreme-Z LGA 1155 is an E-ATX, you'll need a bigger case.
The Cooler Master HAF-X is good. If going along the Corsair route, Obsidian 800D is a beast of a case that will allows you to go the LCS path with lots of room to build.
Also, if you are planning to stick to the 1920x1080 resolution, I suggest going for a 570 or 570SLI. But hey, it feels great to have the best single GPU card without the problems in SLI/CF That is why I also got the same MSI TF II NGTX580 to use at same resolution
