The omnipresent coil whine in almost every laptop I got in past 15 years, gives me at least that nostalgic noise that says "computer is working".

Whish coil whine was configurable :)

At a very low level, it is. I know the individual that made a "diagnostic" for the floppy drive while working as a tech on the Apple I and Apple II designs which caused the drive to whine in patterns that were distinctly ... orgasmic.
