Different form factor

[Jim Cheetham]

A question came in about having an OneRNG unit installed within the
case of a machine by the builder. Sounds like a slightly different
connector and perhaps orientation might help ...

The connector arrangement is the same for the mainboard header as the
usb-A connector (except the header has 2 rows with a n/c key pin at
the end, so the board shouldn't need much/any modifying, just swap the
usbA for a 5x2 header connector (and leave the 2nd row unpopulated.
Keeping it all inside the case is going to make sense for server/data
center use.  Of course additional shielding may be required.
