user13757: I'm using an Arduino Metro Mini (for example https://www.adafruit.com/product/2590) in a project, and want to mount it so the micro USB socket is available through a hole in the case.
Is there an easy way to do this? The main difficulty is that the board has to be mounted end-on to the case, which means you need brackets, which also need standoffs since of course neither side of the board is entirely flat; and the screw holes are at the very end, so no space to spare between them and the case. Etc. If that's not clear, glance at the analogous HDMI mount linked below.
Adafruit sells a complete enclosure (https://www.adafruit.com/product/2709), and there's a similar printable one at https://www.thingiverse.com/thing:936519. I could glue that to the case and then put the mini in there. But that seems like overkill. 
For some breakout boards Adafruit has a special panel mount (like the HDMI one at https://www.adafruit.com/product/3121) -- but nothing I see there or elsewhere for the metro mini.
Any better solutions out there? Closest i've seen here is Mounting Arduino in an enclosure 

user2967: What I've done for my projects is to get PC board standoffs of the right height, and use those to mount the board to the bottom of the case. 
I measured the height of the USB connector and it's distance from the mounting holes, and calculated where to cut a hole in the side of the case for the USB connector. 
I did not look up the USB specification for the depth/clearance of the connector - I just "guesstimated" and it worked fine.
