Don't get a slow 5000rpm drive as a boot drive. You're spending way too much on an enthusiast board with features you'll never use - grab a $125 ASRock Extreme4. If you're not going to use the features that Windows 7 professional has, don't feel the need to spend more for no benefit. Unless you know you'll be maxing out 8gb's of RAM at one time, getting a 16GB kit that's twice the price is throwing money down the drain - also, those heatsinks on the modules look cheesy, have no performance advantages, and only get in the way of after-market coolers. An 850w PSU unit is overkill and Thermaltake isn't the best brand - grab a 750w XfX / Corsair / Seasonic ( to name a few ) which are in the same price range more or less and known to be a million times more reputable and reliable. With the money you saved, you'd be able to get a GTX 670 and a better after-market heatsink like the Phanteks series, NH-D14, NZXT Havik 140, or the Silver Arrow to name a few. The only thing you'd need to assemble it is a spare hour of time, a screw driver, and an optional anti-static wrist band which can be found for $5.
