You may want a third memory stick to take full advantage of the DDR3 triple channel feature. The wattage on the power supply seems a bit low for such a beefy machine and being only bronze certified with such expensive parts seems risky. I had that same model fail on me before so it would be best to keep the manufacture warranty around. I hear a lot of the new keyboards aim for silence as a key feature, but yield diminished performance. In my experience some of the most skilled computer users employ mechanical keyboards. How is that ergonomic design? I see that wireless performance is important in your design. Is your access point capable of transmitting on such frequencies? A tip you might consider is disabling any USB 3.0 devices as they create interference with wireless signals.
