I just built a through the wall keezer setup. I have a bar in the room already. I built the bar to hold two refrigerators, one for wine and one for soda and bottled beer. I also built a wine rack into it. The top is brushed stainless that I had bent locally. This site has been beyond helpful to me in learning how to build a keezer. I did not find any examples of people putting it behind a wall and not seeing it. The closest I saw was someone who cut a whole in the wall and pushed the freezer up to it from the back. I needed to make sure the lines stayed cold and I wanted the taps to be at a nice height on the wall. This ruled out having long shanks that just went into the collar because I would have needed to life the keezer up, that would really make lifting kegs in difficult. I am using all Stainless steel as well as Perlick 525ss faucets. The solution was to build a box that would house the shanks. I took the idea from coffin keezers and just made it externally. Everything works perfectly and the system is nicely balanced. Here are the pictures. I finished the underside of the drip tray so the drain tube was hidden. Here is the result.
