This build here is very similar. It has a similar case, that looks BA.
Motherboard has tons of expandability.
You picked really good RAM.
This PSU is same quality, just a little cheaper and allows for another 670 in the future.
The ASUS 670 is the best you card you can get for the money. It will overclock better than a stock 680.
Since you have thoughts of overclocking, the 3570k is as good as they come.
The aftermarket cooler isn't expensive, but its a great cooler.
