Wow. So you can cold crash in a mini fridge? This is used to clarify your beer, right?
Yes, using in combination with finings (I use gelatin) it helps clear the beer.
May be a dumb question - can you put a temp controller in there without drilling holes? What's the standard way to do this?
Yes--you can pass the cords between the door seal and the fridge body. I could have done that with the cords above, but since I needed to drill a hole for the silicone tubing, I decided I liked the idea of doing a second hole for the cords.
Oh, and would you be able to remove the freezer shelf in order to fit an airlock?
The freezer is actually where the cooling comes from--the lines run through it. Some try to bend it down out of the way, but I was not comfortable doing that. Break a line and the fridge is toast.
The easy solution is what I did, just use some tubing into a jar.
