Some more info on the dimensions of your bar (it looks pretty cool, BTW) would be helpful. It appears that the bar is relatively shallow, front to back, and that there’s no access to the back of the bar (it looks like it’s up against an outside wall). Most small refrigerators or chest freezers would be deeper than your bar. Maybe you could put the kegerator/keezer at the left end of the bar and, if necessary, build a base which would raise the top of the unit flush with the bar top.
