Custom Cases?

I was just wondering if anybody knows of any companies that makes custom cases for systems? I wanna pimp my old NES and SNES to use it for a project of mines from school, but I haven’t a clue where to start lurking.

Even better, could I make the cases myself? If so, what type of tools do I need, without delving too deep into “u nid factory equipmint.”

google vacuum forming if you want to learn how to make your own case. But if you want a more amateur look, you can always try making acrylic cases (these are quite popular) or the classy wood, or whatever your creativity takes you.
