So this thing has a pvc tower that I built myself. I mounted w/ toilet flange and piece of wood inside to sandwich the lid for a snug fit. Also, I used the copper dip tube from an old Killian's keg, which runs halfway up the tower, to keep the beer lines cold. The beer lines run inside the copper, and 3 lines were a perfect fit. The temp control was chi co's 36 dollar model, and is velcroed to the back, keeping the beer at a nice 38 degrees F.
