This is something I'm never sure about. I've pulled others' products apart
and find that the metal case is insulated from the ground plane.
If connecting to the chassis is an option to the end user, should it be
relied upon? Or should it be the only path?

Usually (from what I've found) ground is only through the designated ground
pins on the connector, unless the pcb is part of something like an embedded
injector control, where the body is absolutely grounded.
Comments solicited..
