Here's my tiki bar kegerator.
Holds 9 kegs (7 5-gals, plus 2 2.5's on the hump). 5 regular plus 2 nitro faucets. I also keep 2 kegs of seltzer water cold for the post-mix soda gun and a cold plate in there for the pre-mix soda gun. And there's a chalkboard painted on the front for what's on tap.
The whole tiki bar project started as a something thrown together for a luau a few years back, and since then it's taken on a life of it's own. The kegerator is basically the back bar of the tiki bar.
