Everything in that setup looks really nice, except it looks like you may have skimped out on the PSU and the case. These two things are usually the most commonly overlooked items in a rig.
The PSU, that PSU may look good because it has 680 Watts of power, but wattage is not everything. For one, it has three twelve volt rails which is good, I guess but most people will never use three. And because there are three the two 'good' rails get a mere 15A and the third one gets 8A. Which is really not up to par. Two, namebrands are another important thing in PSUs, don't get me wrong Thermaltake is a good company, but they are not known for their PSUs. I own one, and have been displeased with it. As soon as I get the money I am getting a new one. So, instead of that I would recommend the OCZ Powerstream 520W
or the PC Power and Cooling 510W
For a case, I really do not think that the CoolerMaster WaveMaster is sufficient for all of the stuff you are going to have in this rig, to say the least it is going to be very crowded inside. By the looks of your rig so far I would say money is not really an issue, so I would say go with a top of the line. This case is really nice, the Lian-Li V1200B Plus
, it's huge, quiet, has great cooling, and is top-notch quality. It is a little expensive, but definitely worth it in the long haul.
