that's some very clean work on wiring the rears... did you put them in and then paint the whole room (just curious) ?
I'm guessing you are married, given that there is stuff on top of the racks that is not related to pro football, but I don't see how you could get a better WAF and still have such a usable and component-friendly layout. looks like great airflow and easy access for whenever you need to make changes.
