You've smashed up the DVD Rom (or CD Rom) and the Floppy Drive there. Nice to see inside them

I've done a little autopsy report on it for you, for a bit of fun.

It's the thing on the bottom-right of your first picture you need to smash.
Those are the two hard drives. Edited: That is the hard drive (just spotted that there is only one of them not two)
An effective way is to drill a hole through the disc itself.
