A while back I built a pretty cool kegerator using a Redbull display fridge. Its a round fridge with space inside to fit a 5 or 3 gallon corny keg + CO2 tank.
I got my woodworking friend to build a nice butcher block top for it. He routed the edges along the top edge with a molding bit, and routed an inside groove on the bottom to fit along the lop of the fridge top. I epoxied the top to a bar-coat finish and installed a single tap tower.
Unfortunately it worked for 3 months before it stopped cooling.
