I converted a factory made kegerator. Here are the things to consider:
- You will likley be able to fit more than one corny in there. For a nice clean build, you should swap out the single tower for a dual or triple (depending on how many can fit.
- You should consider getting a dual regulator or gas manifold so that you can have all of the kegs gassed.
- You should buy new beer line and liquid and gas disconnects.
It was a pretty easy job, and I got a good deal on it. In retrospect I would go this route again.
