Since the pins in the header are a friction fit, the only way to secure
them would be to mount it onto a PCB. If you used a 90' angle header
you could mount it onto the PCB and provide access via a slot cut in
the case. I did a similar thing with a 10 way but soldered it onto the
double sided PCB edge.
