I decided to make my conversion a little more involved than just drilling a hole and installing a tower. I replaced the plastic top that comes with the fridge with a 2'x2' piece of 1/2" plywood. I'm going to use copper flashing (used for valley areas in roofing) to cover the plywood, hopefully making a nice looking small bar top. Later on when I add a larger bar the fridge will already have a nice looking top and I won't need to change that. As the copper ages it will look very cool.
