Update:
I finished priming and painting. The finish turned out pretty good, IMO. Not perfect, but it matches the stand well, and the flaws are only visible upon close inspection. It took 1 coat of gray primer and a out 3 coats of latex semi gloss black to finish. I sanded in between with 150.
I then installed some black plastic mosquito netting to seal the inside from jumpers. Finally, I added the 6 3" case fans for cooling. Next will be adding the T5 lights and wiing it all up.
