One of the best cases I've come across has to be Shortbread which is currently languishing and lacks support
I know spending almost as much on a case as for the RPi seems strange but Shortbread does have two major attractions:
the SD card is well protected and doesn't protrude from the case
the power connection is switched to the end of the case - three cables together
I've no interest or involvement in the Shortbread other than wanting one
Please have a look and support this project. Maybe a miraculous turnaround will see it go into production and I'll get one!
