The 'green' hard drive would be a really bad idea considering the other parts youre putting into this. Go for the black edition.
the power supply could be better. I dont think cooler master is known for making great power supplys with the exception of their high end 1000W+ stuff. im partial to corsair myself. it would be too bad to spend all that money just to have it asploded by a bad psu.
It may also be a good idea to spend a bit more on a case. a little extra money will save a lot of cuts on your hands during assembly and it will be quality enough to last for several builds and more, depending on how quickly you upgrade. if you plan to game with that case and you use headphones, notice that it doesnt have a headphone jack in the front. my current case Buy the Cooler Master Storm Scout ATX Mid-T Blk Case at TigerDirect.ca
is always what i recommend, unless you had your heart set on the fan speed control, which it lacks.
