I needed case for my RasPi I used for Octoprint. I have some sensors and camera attached so I needed design allowing easy way to detach RasPi in the case from the printer.
I used 10ways plug and socket - currently using 4 connectors but I have comfortable option to use other 6 - to control printer's enclosure extraction fan and lights for instance.
I used short and long camera ribbon linked with this connector so I can disconnect camera without opening case.

It is designed for 40mm fan.
