Are you building a collar or using towers? I am building a keezer as we speak also, and you cannot drill holes through the front of the chest freezer for the shank. The walls of the freezers are lined freon tubes. If you break one of those your screwed. Also you might want to use the same faucets across the board. Perlicks have different flow rate then standard faucets so serving pressures may be different. Other than that you look good! You will obviously need odds and ends like shrink wrap, wire ties, QD's, ect... good luck! Im sure we will both enjoy our new friends!
