The freezer has been working like a charm. The big problem is that the lid that came with the unit was only an inch thick and not so well insulated.
I started with 1/8" G10 Epoxy Board. Basically circuit board material. I used Ted's table saw and started cutting and epoxying.
Once I made the lid piece, I used it as the form for the surround. 7 days, start to finish. If I was charging myself US yard rates, this would be about a $2000 lid. Good thing I work for free.
