Should there be anything from keeping me from buying a 5.0 cubic ft. chest freezer (like my fermentation chamber) and drilling holes in the top to make a kegerator? Are there any gotchas? I've seen the chest freezers with collars, but is there any reason to no do it the "easy" way? Basically like the Sanyo kegerator but with a chest freezer. I haven't seen a pic of any yet though...only collared freezers...
