I'm putting compartment #2 at the bottom to make airflow for the psu and graphics card. If I can get some extra fan mounting clips for the TRUE, I'll put the extra fan i have on the otherside, like indicated in the picture (left of #4)
and the back panel of my desk seems like it'll remove nicely.
The only waste of course, is the 200mm fan, which is being blocked by the the top of the desk, but that's something I'll have to live with, at least it'll bring the warm air up and have it blown through the exhaust.
