Any one ever have trouble from electrical shorts due to metal shavings
falling on a connector?
I was thinking of either using a smaller machine screw and nut or
maybe just covering the inside of the hole with putty, tighten the
screw and finally remove the putty. A magnet would only help with iron
screws and I see many that appear bronze or even possibly aluminum.

What is so hard about cleaning the holes in the case with a reamer before
you assemble the computer?

Can you explain what you are trying to do again real slow. :)

I don't understand what you are asking.

Plastic is a good shavings catcher.

The screws are either steel or brass, not bronze or aluminum.

Considering where those screws are located, any metal chips probably
fell harmlessly out of the way, and setting the computer case upright
and tapping the case will make them fall to the bottom. Don't bother
blowing them out with canned air. Use masking tape at the screw holes
and the bottom of the case to collect any chips. You may also want to
break off any chips still attached to the holes.

You may want to drill out the hole and tap it for a machine screw. A
"bottoming" tap is necessary if clearance is tight.

If you use a nut, either use a kep nut

and glue it on with epoxy or rubber cement, or use a pem nut

(www.wiilink.com/images/20070223/5-B-5.JPG).

Pem nuts require drilling a much larger hole and pressing the nut into
it (hammer, vise grips) but are permanent.
