Cooling the cabinet
So obviously cooling was going to be an issue so I had to get creative.
I used a start collar at the top going from 8" to 6" ducting. I mounted the start colar using a magnetic sheet to seal the start collar to the top of the rack to prevent air leaks.
Then from there it goes through the wall into a closet where it is connected to an inline 6" A/C Infinity duct fan that is mounted at the ceiling and blows the hot air up into the attic.
This may not look pretty, but lemme tell ya, it dropped the temperatures in the room significantly.
