[hpsdr] Card dimensions, current and future.

[Orval Chadsey]

Regarding the case and cables front/rear vs front
panel/display/switches:

I like to have my cake and eat it too...

Make a front panel that is hinged at one side, with a cable access
cutout opposite the hinge. 
Allow space behind the panel for a front panel interface board. 
Both a blank and a pre-punched panel could be made available. (if a
standard layout is agreed upon) 
It could even be designed for both right and left handed hinges.
