You have the wrong RAM. That RAM is tri channel meant for a socket 1336 build and you want dual channel. Also the gtx 580 is outdated now. It's a power hog and is way behind the new generation cards out now. Another thing...that CM EVO cpu h/s comes with a small tube of MX-4 thermal compound which is about as good as it gets so you can take that Arctic Silver off that list also.
