Building it myself.. It will actually be my first time. I am going to have someone helping me out that is pretty proficient but I just wanted to ensure I got the best deal for the money. I had heard the Cooler Master HAF 912 was mediocre with default case fans for cooling so that's the reason I upgraded the case fans.
I have the CM HAF 922 case and V6GT and they offer great cooling. I would stick with the 212 EVO as the V6GT interferes with RAM and has an awkward mounting system but would consider the HAF 922. Everything else looks great.
