so "grounded together"?

Any other helpful points about running a PC on the bench this way
would
be greatly appreciated.

I've built a few dozen PCs over the years. I would never bother
running the system out of the case. Mine nearly always work fine ( one
exception ) and then you'll have to unplug and mount it anyway and
plug together again. You're more likely to screw it up OUT of the case
so why take the chance and waste the time? BTW the case / power supply
I'm using now - the wife's machine - is on its 4th motherboard. The
latest change 2 weeks back took an hour - so short because the old and
new boards are nearly identical and didn't require any re-installation
of the software. The newer board can use the higher power/speed Phenom
II processor now in it.
