Could save some money on your PSU and CPU cooler. Unless you want to OC above 4.5 Ghz the 212 EVO is perfect. And you can just get a cheaper 750W which is perfect for future SLI. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021http://www.newegg.com/Product/Product.aspx?Item=N82E16835103099
Then you don't really need 16Gb of RAM for a gaming computer is way overkill. If you
do want to upgrade it later it's easier and the RAM in the future will be cheaper and better then it is now. Just make sure you get low profile RAM so your hit sink will fit in.
Could also save on the case and move to a Corsair 500r. It's an amazing case, great cooling, fan controller, LED switch, amazing cable management, ect. But cases are pretty personal choices.
