Extra fun fact about tinkering: The air gap in the transformer means that your GFCI won't detect a ground fault, and your circuit breaker won't detect a short because as far as the mains line is concerned, there is nothing wrong with the circuit.
This doesn't happen under normal operation, because the chassis allows for a short and/or a ground fault. But when you take that chassis off, and especially when you take the transformer out, you're putting yourself into a life threatening situation.

TL,DR: Microwaves cook things, including you.
