+1 to Stulid's build as you asked for best possible gaming rig.
However if you are going to use it for more than gaming then either get Stulid's and later a SSD, or get Redmint's build.
The CM 690 II is a quality case, the only niggle I have with it is some of the screws seem poor quality as they just ripped up when I used my screw driver (Correct size). It's not really an issue, but I came across it when I chose to remove the unnecessary parts such as the cages etc.
Overall I am very happy with it.
