I will be putting some face-frame style cabinetry around the front of the keezer stained the same color as the wood trim on the lid. I just need to find the time to do so. I've had 4 weddings to go to this year, and another one this weekend. I'm starting to see why it took Jester so long to finish his build.
Take a look at his cause I'm likely going to do something similar. Face-framing with pocket holes securing everything. Firring strips to screw the large pieces together, and 1/2" rabbiting around the inside of the frame to hold a 1/4" sheet of oak plywood.
I still need to rig up all the plumbing, but I have three taps operational at the moment. I wired together two computer fans using 9V wall wort I had from some old portable house phones. One cools the coffin, the other blows air around in the freezer. They run constantly, and it definitely helps to keep the temps consistent.
