Aesthetics are of little concern to me, I am just looking to toss it in the garage next to the bins and next to the work bench. All it has to be able to do is keep temperature at 3 degrees and Im happy.
Im not so worried about efficiency either, You aren't running it at its full capacity when using it as a temperature control for fermenting, and they are hella better than stand up fridges. Mate of mine uses a chest freezer as his primary fridge at home and says it costs him 12$ a year to run.
