Couple of observations:
You don't need 16GB of RAM for gaming. If you do want 16GB for, say, video editing get 2x8GB (rather than 4x4).
Corsair SSD ok, but prefer OCZ Vertex4, Samsung 830, or Crucial M4.
You don't NEED a full tower case, but, obviously, nothing wrong with that, if you particularly like it.
I take it, you are thinking of 2nd GPU, in SLi, at some stage. 750w PSU more than enough.
Only observations. All will WORK, as is.
