It's possible to disable the USB ports in the BIOS settings. It's also possible to disable the optical drives. I've seen it done in a secure facility.
Of course, the BIOS password can usually be reset by clearing the CMOS, which may require opening the case.
I doubt that there's any practical way to lock down a PC from users with unlimited physical access to it.
