I just finished a tutorial complete with shopping list on youtube:
I made this kegerator to serve beer and/or soda from a chest freezer. Total volume on tap: 11gal at once distributed between 5 taps (4x 1.5gal, 1x 5gal). I have never seen anything like it, so hopefully if you decide to replicate it in some way, I have taken out a lot of the guesswork. Also included is what it cost me for shipping, something that varies often and try to catch the specials when you can.

You will need a drill with bits, adjustable wrench x2, paintbrush, handheld saws for the wood, sanding supplies, screwdriver, teflon tape, measuring tape, hammer, soldering kit (if using the wired temp controller).
That may seem like a lot, but when you factor the commercial kegerator price in it is a steal. Kegerator.com has them starting at $500 but only for a single tap ($740 for double tap), not 5! If you went with more or less taps than my 5 on this DIY project, your cost would change by about 15% per tap added/subtracted. If you're on a tighter budget, you could start with a couple faucets then add more as your wallet allows. Would it still work as a freezer if you needed it to? Yes, as long as you change the temperature setting.
