that's why i always have some thermite on hand. it's very cheap too but you have to be super careful storing it, there's a label on the powdered aluminum saying never get it wet as it'll start reacting.
from the Al powder MSDS:
"Dust may form flammable or explosive mixture with air, especially when damp. Reacts violently and/or explosively with water, steam or moisture. May ignite or explode on contact with moist air. May cause eye and skin irritation. May cause respiratory tract irritation. Air sensitive. "
although i'm pretty sure I'm on some FBI watch list now.

As for "Don't enter the correct BIOS password within 30 seconds of a boot attempt? Buh Bye, HDD."
Well that'll just start a fire and you'd be liable for arson. You can't really put out thermite once the reaction starts.
