I've decided to share the only things that may make my kegerator unique. The first pic is the dual regulator mount. I used computer fan mount screws to mount it to the fridge door. I'm quite surprised by how solid it ended up. Not so much as a quiver or shimy when adjusting pressures.
The second is of the tank mounted in the cabinet next to the fridge. I drilled through the fridge sidewall, and through the side of the cabinet. Ran the hose through both and set my 20#'er in the cabinet. I have a carpenter friend that has offered to shorten the drawer for me. It's my basement/man cave kitchen, so SWMBO was only slightly concerned
