Zap-proofing a switch from static?

How can I make the on/off and reset buttons for a computer more
resistant to static electricity? Would putting a 100 ohm resistor in
series with each of the button's wires and following that with a MOV
or other clamp do it? These buttons seem to work reliably even with
1,000 ohms total in series.

Is there any practical way of doing the same for the keyboard and
mouse, not necessary for those things but for the computer they're
connected to?

I'm looking for protection that's almost goof-proof and doesn't
require the user to touch the computer case or an anti-static pad.

This is very difficult to do reliably. The best is to have an optical
coupling system, but will be involved to do.

Have you thought of investing in a humidifier? That would be the most
viable solution. We keep our humidity in the range of about 40% to 50%.

Not practical since the computers aren't exactly 100% indoors, and this is Arizona.

Seems to me that painting the surface of the power and
reset buttons with conductive paint and attaching a small
braided wire from the chasis to each one might help.
You could do something similar to the space bar of the
keyboard and the upper surface of the mouse.

You could move to the East Coast, all of the electrons have frozen there
recently.
