You can get a an H77 board which will be less expensive because you cannot overclock that CPU. If you REALLY plan to SLI soon, get a z77 board.
The PSU/GPU look fine. I would get a more well known case form a reputable manufacturer like Corsair, Antec, NZXT, Fractal Design, etc. Not that your case is bad, just that you can get a better quality one for the same money.
I think you missed what I was saying. That board you chose will be fine. It is just old. It will not affect CPU speed. I said you CANNOT overclock that CPU no matter what. It is not an overclocking CPU. An h77 board is better quality and would be a better idea. A z77 board will ONLY be needed if you plan to SLI.
