Very cool. I think I've got a similar sized freezer and will now have to consider what you have. I like the idea of a tower/coffin but not too keen on having it cooled or a tight access if I need to change things out. The split lid definitely avoids worrying about knocking the tower off when opening though. Mine can fit 4 maybe 5 cornies with the CO2. Do you have any dimensions of your wood work and or pics of the inside of your tower? Thanks for posting!
