The CPU is a great choice. The motherboard is pretty good, though I'd also look at an AsRock z77 Extreme4.
If you're overclocking, then pick up a $30 Hyper 212 EVO. If you aren't, then get an i5-3470 and an h77 board for less money.
Never heard of that brand of cases, but that model has poor reviews on both newegg and amazon.
The power supply... you want slightly more wattage with more reliability. The power supply is THE most important part of your computer, because if it fails, as cheap ones are want to do, it could explode, light the computer on fire, or totally fry other components.
Also, you're forgetting RAM.
