Here are some pic's of what I did with my 3.6cf Magic Chef
Put a 2x12 cuff around the front
Put temp probe and fan wiring through empty back of the unit. Will be doing the same with CO2 lines soon. For now 5# tank sits on shelf in back.
You see two in here now, it holds three and the third gets a picnic tap.
All set and ready to drink
So, yes you can make your MC 3.6cf fridge into a very servicable kegerator.
