One of the things that always bothered me with these boards was the lack of mounting features. Rather than hot glueing the board into my enclosure, I made a clip to glue in, then I can snap it into the clip.

I had to make clearance for soldered socket. Not sure if it will fit other models, these are the only ones I get from aliexpress.

The holes will fit a M2 screws, or M3 with a little heat.
