Awesome build. What's mad is that I hadn't seen this before I ordered my components and it's very similar to what I had in mind.
I have a question if you wouldn't mind, how do you find the airflow through the back of the case? I have a 480 radiator which is a wee bit thinner than yours and I have 6 thermaltake premium led fans because they only come in packs of 3. I was planning to have 2 in push pull but I'm worried a lot of the heat that comes out of the radiators goes all through the back of the case and not out the vent. Once the inside of the metal case has a bit of positive pressure I assume the main flow of hot air does go out the case but the case it's self might get hotter?
Cheers for any input mate. Again, beautiful build
