I got an old freezer for free. The cooling coils were also the shelves and that made it impossible to put anything in it. So I extended it about 30" or so with some SIPs (Structural Insulated Panels). I have a Love controller wired to it along with a fan that blows over the coils when it comes on. It works great. I have a Munich Dunkel largering in it now.
Please note the high tech device that I used to hold the door closed, a 25# weight. I'm getting more use out of it now then I have since I bought it.
