[senit] Power switch guard

Hi

I am sure this thread has come up before, so forgive me.

Does anyone know of a good product to protect the power switch (on / off
button) on a PC? I saw a key operated one somewhere and wondered if these
are in use or if anyone has any other ingenious solutions to computers being
switched off which does not involve bulky cabinets.

Thank you,

Claire Barnes
