I guess you just need a PC from the early/mid 1990's with a soundblaster/clone sound card. Those cards overwhelmingly didn't have good power filters on their audio amps/etc and when the gain was turned up a bit you could hear the ISA/PCI bus noise.
I remember my PC made very distinct noises when scrolling text, compiling, and various other operations.
I vaguly remember a reading somewhere a couple years ago that someone had hooked up a click noise to linux syscalls and context switches for this basic purpose.
I just wish machines still had disk I/O leds. My laptop (a dell) is one of the last machines I've seen with a disk activity led, because it switches the charge led to disk activity with a fn key combination.
Also, if you want satisfaction there are various industries where computers are used to control mechanical devices. I worked in one where a large robot was being controlled by our software. Nothing more exciting than writing some code and hearing that think whirl and clunk away. Or somewhat frequently banging against end stops and the like when we had bugs.
