Touch screen display enclosure

I'm little confused on how I am supposed to acquire an enclosure for an arduino hooked up to a touch screen display.

There are many tutorials showing how to connect arduino to a touch screen, but none of the resources show where to get an enclosure/case in order to protect the board/make it look better.

I've tried searching for "arduino touch screen enclosure" in google and amazon, and I either get irrelevant search results, or show enclosures for the rasp pi?

I'm shocked that there's not way more resources on this as I imagine it's a very common need.
