I'm going to suggest that you wait on getting a cpu cooler for now. It's an item you can buy later on, that will allow you to overclock better for much better performance with the integrated gpu, however, buying better quality parts now will assure that your system will last longer. I.e., the Psu you had listed was crap. Also, with the integrated gpu, there is a noticeable performance increase if you get faster Ram. I've also upgraded the Case, since I'm not 100% sure that the cooler you had originally would have fit inside that case you had picked out. This case is a great one for the price, and will last you while you hopefully completely upgrade the Pc to something more powerful.

Again, you will want to eventually buy a cpu cooler, I'd just save the 30 dollars NOW. That 30 dollars upgrades the motherboard, Ram, Psu, and case. I went with a better chipset for the motherboard as well(will help overclock better too). I also dropped down from the 6800k to 5800k since the reviews I've read don't really support the 6800k over the 5800k for the price increase. So might as well save the money.
