I have a chest freezer ferm chamber that I'd like to outfit with all of the fixins to put beer on tap occasionally. I think i can pull this off with a 2 faucet tower and little else, why would I build a coffin? Is it just so I have the option for more taps (this is a small chest freezer, so that's not happening anyway), or is there another reason? I just want to make sure I don't start the build and then realize why I needed a coffin later on. Any input would be great, thanks!
