Something to remember here is:  There is NO SUCH THING as a *completely*
secure computer.

EVERY COMPUTER has the ability to be cracked in to.

The best thing you can do is make it more difficult/expensive for a person
to crack your computer than it is worth to them to find whatever you may
have on your system.

There is no way to prevent someone from gaining root access to your box if
they have physical access to the machine.  Even a BIOS password can be
easily reset if you have physical access to the machine.

Removing the monitor, FDD, etc, is not hard to overcome, either.
