So after many batches of both extract and all grain, my cohort in crime and I have purchased a mini fridge to convert to a 2 tap keg system. Any thoughts, pointers, or preferences on what to look for with kits?
First, you'll need to make sure that where you drill at the top there are no coils, if so and you drill through it, the fridge will be toast.
As for Kits, they are all by preference of what you want and there are a slew of "How-To's" on this board on converting a fridge at what parts you'll need. There are also instructions on how to locate the freon lines in the fridge so you don't drill into them as well.
