I also bought this freezer for my keezer project. It fits 4 corny's on the floor along with a 10 lb Co2 tank, and I have a 3 gallon corny on the hump for pop, along with a 5 lb Co2 tank for the pop and force carbing. Works great! I had to cut the cord on the alarm in order to put the collar on. No issues, I just taped the ends and left it unhooked.
