So I am getting ready to do my first keezer build. I've converted a refrigerator before with no issues, but this is my first keezer. I almost certain there's nothing to worry about with drilling the hole to mount the tower, but I am concerned about mounting the manifold on the inside. I've done quite a bit of searching and can't find a schematic of my freezer, so I don't know if there any lines to worry about in the sides or back of my freezer. Is there a standard configuration for a top loading chest freezer or does it vary by manufacturer? Maybe I should just figure out a way to mount the manifold without puncturing the inside wall of the freezer. Thanks for any help. Cheers!
