Nice job.

There is a fair amount of copper in microwaves. So, it is possible to make some money by scrapping the units for parts.

There are a few dangerous things. The magnetron contains beryllium oxide ... which is poisonous. The high energy capacitors hold a dangerous level of charge and can zap people even after months on non-use.

I guess the most dangerous part of the microwave are the cats that invariably end up curling up in the units.
