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:
Manufactures are now embedding the condenser coils in the outside wall of the freezer, just under the thin metal exterior skin.
See where modern freezers place their condenser coils below:
When someone builds the outer box/coffin too close to the freezer they eliminate the freezers means of "cooling" the condenser coils and thus the refrigerant does not cool off properly before cycling back to the compressor.
A Keezer build like this will work in the short term. The compressor will have to run longer and thus your electric bill will be higher then it needs to be. In the long term this will most likely burn out the compressor early, due to the freezers inability to shed the heat in the little air space between the freezer exterior walls and the inside of the box/coffin.
If you intend to build a box/coffin around your freezer design in some cooling fans to circulate the air between the freezer and the box/coffin. I suggest you use some fans that are designed to cool audio/video equipment that are build into high end entertainment centers, like the fan below:
These fans are 115v so no transformer is needed, and if you are controlling your keezers temperature by a separate thermostatic control, you can also plug these fan(s) into the same power source that way the cooling fans only are running when the compressor is cooling the freezer.
Best of luck.
