I happened across a refrigerator that perfectly fits my conical fermenter. This ferment was purchased a few years ago from Stout Tanks and Kettles. The refrigerator is manual defrost, which is something nice to have, when you are going to add a temperature controller. Yes, that implies I am going to add a temperature controller--or already have. I will post up some pictures and design notes on the temperature controller I built at a later time. You could also just hook up a Johnson controller and call it a day.
Something to note is that the Johnson controller (A419) is only single stage. That means it can turn one device on only. So, it functions as a heater or as a cooler controller but not both. I opted to create a two stage controller...sometimes all you need is cooling, but in Nebraska, my garage gets so cold, that I might need the heating too. Think diacetyl rest in the winter.
