I fitted a 500Ohm linear pot in series with my PC speaker.  I tried a
logarthimic one at 500Ohm (since it was a volume control) but it just cut the
volume off too quickly.  The 500Ohm linear works well, and when turned to
full resistance the sounds are just audiable over the (noisy) fan, when
the resistance is off the POST beep (when you turn the computer on) could
easily be heard in the next room!

If you want to cut out sound completely, get a pot with a switch.
As for mounting I put mine through the front keyboard connector hole
(which wasn't being used)... it looks like an integral part of the
computer now!

Good luck!
btw. if you're drilling any holes in your computer casing it is preferable
to use a hand drill (human powered) to avoid creating extra screw holes
in your motherboard 8-)
