Purge!

[Norwegiantweaker]

You make sure your hard drive reside in external cages, and have some archer-grade spring loaded heavy duty heavy-ass bolt right above it, with a big red button next to you that release the mechanism, which effectively pierces through the hard drives, breaking all platters, sending debris all over the room and potentially severely injuring you and anyone in immediate vicinity.

Or anything less medieval that can also physically damage platters on the HDD. Tesla Coil? Silenced Gun? a Sledgehammer which can also be used as self defense after the act.

Whatever you come up with, please make sure to put a raspberry pi-powered recorder with auto-upload-to-youtube function next to it so we can see how it worked out if you'll have to use it

LOL. now i just HAVE to do this. damn you and ur genious ideas!
