That would be Frasier Farrell, IIRC. I guess he is not on the list
anymore, but oddly enough I saw excerpts of a email he had written to
Fred Langa, the author of the Langa Newsletter I subscribe to that
was mentioned here recently, complaining about how some of the
parental control software (Net Nanny, etc.) incorrectly excludes
access to his astronomy pages because of the common astronomical
expression "naked eye" as in "naked eye observation".

I routinely test motherboards resting on insulating, antistatic foam
with nothing more than the power supply and a video card installed.
Any grounding considerations are probably for EMI
(E_lectro_M_agnetic I_nterference) shielding which mostly simply
effects how much interference you get on any nearby electronic
equipment (tv,radio,hi- fi, etc). This might be a concern in an
apartment/flat/condo setting where your neighbors are close and you
share the buildings electrical system. If you live in a
single family dwelling (house) you'll probably be the only one
experiencing any interference. If shielding became necessary you
might be able to achieve some measure of protection by lining the
inside of your non-metal case with metal window screening, heavy
aluminum or copper foil (preferable) being sure there is only contact
at the motherboard mounting holes that would normally be secured with
a screw as opposed to those holes that are supported by the plastic
standoffs. I hope this is enough to get you started.
