Thank you guys, never thought about the fact that the compressor slides out and it has its own plug @@.
I bought this sucker on Craig’s list, 350$ I took the legs off and bought caster wheels so I can move all of its 400#'s. It is all stainless inside and on top, I was thinking about replacing doors, until I called and found out that each of them is 700$!!! The hinges and interior door brackets were destroyed by rust, I rebuilt them and reinstalled stainless hinges and screws.
I didn't have to drill into it, I just removed a solid disk and there was a whole that I slid the (homemade) co2 manifold into.
It’s in a small workspace so I am adding an exhaust fan to send the heat out of the area it is in, you can see it on one of the pictures. I have a ½ barrel keg that was in the center and I think I can hold at least 6 corneys per door, guess I need to brew more!
