These boxes are cheap, plentiful and are designed for house current which is more than hobby microcontrollers probably handle. I suppose they can be painted and if you design a board to fit then you may have a profitable design. Engineers are afraid of selling electrical products to the general public but I would feel more safer with some projects in these boxes.

There just needs to be a modular PCB design for the 16F or 18F pic.

Just be careful of metal splinters, wear heavy duty gloves and use safety glasses. And use a file for sharp edges.

I like using plastic boxes. They are cheap and easy to work with (drilling etc...)

I used to get them from my local electronics store which has just closed down

The ABS plastic electrical boxes are cheap as well.
Most any hardware store or Bigbox has them.
The junction boxes are the best as they are sealed (watertight)
