I purchased a back bar Beverage-Air commercial refrigeration unit with the plan to convert it into a kegerator. I have about twelve 5 gallon cornies and it fits all of them with plenty of extra room leftover. I was considering going more on the cheap with a chest freezer conversion but really wanted the ability to build a bar around this thing in the future and loved the idea of being able to open the doors out from the bottom for keg loading/changing. I also found a killer ceramic 2-tap draft setup on Ebay which I built into the rig. I went with a 2 inch copper pipe to encase my 2 lines. The first beer pulls cold with no foaming at all and I don't have to have a fan to move the cold air up into the draft system.

Installing the post with some great stuff around it to hold it in place and insulate:
I could have purchased the bev-air unit with the taps already installed but it is more expensive, plus I wanted to have the tap location in the center and use my own instead of the stock ones they provide. I couldn't be happier with it.
