I made one. I took an old 21 cu ft top freezer fridge and made it all one chamber by taking out the freezer floor, bypassed the defroster switch and adding a Johnson controller. The cooling coils in mine were in the back. I use the shelf system that was in it and can get four, maybe five fermeters in it and can get the temperature below freezing if I want. I sanded it down and painted the body with rustoleum hammered silver paint and the door to the freeze compartment with chaulkboard paint. It doesn't look too bad and it works great.
