Getting primed. As you can see in the pic, there isn't even a full coat of primer on it at the time, but I used Kilz primer. I should have gotten a can instead of a spraypaint, and had it tinted, but oh well. Cab will be satin black when everything is said and done. I gave it a quick few coats of a gloss black, but was VERY disappointed in it, and decided on a Satin finish, which at this time isn't done yet (hopefully this weekend).
You can see a rectangular cutout on the back panel in the pic. I decided that as opposed to a door in the rear, I'd use an air vent grate as a pseudo-access door. I shot the grate with the same satin black paint, and it will be attached by bolts/wingnuts. It's a very simple solution, but works very well and allows full access to the rear of the PC.
