I'm just finishing this up. It was a frigidaire 15.5 cubic foot freezer. Plenty of space for 6 corny's or 1/6 barrels. The beer gas tank isn't inside now, but that's because the smallest tank size I can exchange around here is 40 cf. I scored the tap tower off of ebay for a couple hundred bucks. It is for a glycol system. Instead of glycol, I bought a 2 gallon bucket and a fountain pump that just circulates cold water through the glycol lines. It works quite well.
