You have a Atari ST sitting around ?
Why not put that in the bath with some bleech and acid ?
You can keep all components inside, it don't matter.
If you have a webcam you can set up a time-lapse photoshoot so we can all enjoy it melting
If that fails then you can always take it outside and cover in petrol. If the petrol don't melt it then get a match and stand back
Make sure you get a good long cable for your camera so we can all watch
And when you're finished get a good extention lead with a fuse and power-breaker, and connect 240v AC to the midi ports ! haha
