Some misc thoughts, about changes I would make if I were about to build the system for me. YMMV:
* 128gb SSD would feel cramped for me. Fine for Windows+WoW+LoL, but if you've got a steam account with much on it, you'll want more.
* Would switch to a cheaper case - I just bought a Coolermaster HAF 912 for $60, free shipping from Amazon, and I'm quite happy with it.
* The GPU is very solid, but I would personally shift a bit of cash from that to a bigger SSD. 'Course I have half of the games on Steam so.
Else, looks nice. Watch out for static when you build it! Enjoy Not much feels quite as nice as moving to a new PC.
