I have noticed a lot of people that are building Keezers from chest freezers are building some very nice Boxes, or as some people call them Coffins, around their chest Freezers. These are some very impressive Keezers!

If done correctly this will be no problem, but if the box/coffin is built too close to the exterior walls of modern freezers, it will result in much higher operating costs in the short term, and premature failures of the compressor in the long term.

The compressor needs to get fresh air and many of these Keezer builds do allow for the compressor to get nice airflow.

The problem I am seeing in these box/coffin builds, is that modern freezers today do not have visible exposed condenser coils like in the past.

See an example of exposed condenser coils below:
