1) The inside of the freezer should be made from a water tight fiberglass or plastic and its compatibility with our coolants is something you need to test, especially at high temperatures like 50-60C.
2) The chillers on most chest freezers are not very powerful, as they are design to work very slowly and with the lid closed, so in most cases the chillers on these freezers will not be able to handle the heat generated by a single miner which with new units can exceed 3KW.
3) You will need to add a circulation and fluid cooling system, when you do this make sure you are using an epoxy or similar sealant to ensure your new plumbing into the freezer doesn't not leak.
These units are nice because they often have a locking lid and if you can route the plumbing and the cables in such a way to keep use of the lid, you get a nice quiet tank that looks like - yup a chest freezer...
