I am still working on a full write-up on this, but here are some teaser shots from the kegerator.  The AC unit in the picture is a 10,000 btu unit, but I will be using a 5,000 btu unit in the final build.  Those are your standard 5 gallon corny kegs.  It will also fit carboys for lagering purposes.  I plan on expanding it to have separate areas for tighter temperature control for fermentation.  The ducting is for running the beer lines up to the faucets, I am using a duct to direct some cold air up to keep the lines cool.
