I've bought this board to adapt an M.2 SSD to a U.2 Cable: https://www.amazon.de/gp/product/B072BXHQ4J
It was by far the cheapest board with Prime delivery, but it had no case, it was just the bare PCB. So I made one myself!

The PCB is held in with plastic "rivets". Put the PCB on, heat up the rivets and press them flat.
