Well, I used the RPi3 as my main computer for a long time.
One had to use omxplayer, a special media player, tho, and
when that run one couldn't background it and use the computer
for something else, probably because it monopolized the
resources in order to function at all.

Now on the stationary I can use mpv which is much better. (I
don't know how it is with the RPi4 in this respect.)

Other than that the RPi3 as a workstation was pretty much like
any Unix system I've used. But I prefer Debian (vanilla
Debian) to Raspbian, which I heard is now called the RPi OS.
It is a hardware-specific Debian derivative for the RPi, much
like ev3dev for the LEGO droid.

There is fancontrol (pwdconfig(1)) but I don't get it to work
... The BIOS (UEFI) can maybe be used but I don't have/use
a mouse and I dislike the UI ...
