Don't give it any USB, CDROM, Firewire, or ethernet drivers and it won't have any USB, CDROM, Firewire, or ethernet devices.
How to do this depends on the distro. There's a few options. If these things are all modules, you can blacklist the relevant modules and they won't be able to get these modules loaded without first logging in as root. If you're compiling your own kernel you can just leave these options out entirely.
Of course, none of this prevents them just popping in a livecd and booting with that. They could do that on a mac too.
For that matter, nothing prevents them taking photographs of the screen, either.
