There really isn't the possibility for "screaming electrical death" unless you go through great lengths to attach something where it doesn't belong (and hence, obviously doesn't fit).

Also, nobody in their right mind would leave their computer plugged in while working on its internals.

Actually, it's not such a stupid idea, as the case is earthed when plugged in, which can help prevent damage through static discharge. I'm pretty sure my Intel SSD's leaflet actually recommended it. You're very unlikely to get an electric shock from a PSU unless you literally stick bits of metal through the grilles or open it up.

Given the recent commentary on the new design for a folding version of the UK mains plug, I should share a tip a friend gave me - you can put a UK mains plug in 'upside down' to an adapter strip.

This means only the earth pin is connected, thus earthing your case but without running the risk of having live connected, even if isolated via a switch on the PSU.

I'd never actually heard that. Interesting. I just use a ground bracelet when working on my computer to prevent static discharge.
