We've been using a small chest freezer as a kegerator, but it could only hold one keg so it was time to expand. Luckily my family has a huge barn filled with old junk, and part of that junk was a Kelvinator from the 1930's (we are thinking 1933). Thanks to a HVAC inclined father in law we had the beast up an running with a new compressor and all shined up with new paint and gaskets.
The only issue is that I don't think I can bring myself to drill holes in it, so the next improvement will be a tap box of some sort.
