This is my second kegerator, the first was a fridge style with tower. That one is now the fermentation fridge, this one used to be the fermentation chest; they've just switched roles. Now, I can have 2 beers on tap still, possibly a third in the future for a stout faucet/nitro setup, and have space for a lager or two that I can forget about.
This was definitely a challenge. My stepdad did the work, since he's a woodworker. I'm sure he made it more complicated than needed, but it turned out awesome.
