Indeed. One actually useful case I found was using an rpi with shairport-sync + owntone to allow airplay streaming. I got a quality DAC from hifiberry [0].

Another use was running HomeAssistant, but I migrated that to my real server.

Another use is having an external InfluxDB + Grafana monitoring setup so I can view stats even if the server goes down.

Lastly, you can take X amount of raspberry pis and run a kubernetes cluster with k3s. [1]

Since I don't play with my cluster much, most of my pis just sit around gathering dust...

That's a big one, unless you're doing actual IO on the Pi itself, if you have a server you can likely virtualize or docker whatever you were going to do with the Pi.

I have a few Pis around the house, but likewise, the primary use-case that has stuck has been as an Airplay target (using shairport-sync). I'm not using a RPi specific DAC, but rather a cheap USB DAC. I have two of these around the house and haven't had to touch them for years.

The second use-case I have is as an Octopi server to run my 3D printer. I have found this interface to be significantly more user friendly than uploading new designs to an SD card.
