Are there better/cheaper alternatives to run home servers than a good old raspberry pi?
Discussion
Depends what youโre aiming for:
Power efficiency?
In general I like arm. I was a bit disappointed with the rp3 but the 4th runs smoothly, so I can imagine that the 5 is doing fine.
Other options I like are the APUs
rp5 is great the ram increase is very useful, especially if you're running a node
What I really like of the rp5 is the M.2 support that would definitely help. Though my rp4 still manages running a #bitcoin node, and a #monero one quite decently on an #OpenBSD (not exactly a fast OS). N the top of that I had it running a netatalk for #timeMachine backups but that was on the very limit.

used laptops that have batteries & native durable storage vs adapted for USB ๐
I'm running out of old laptops at this point ๐
Not cheap, but not super pricey...
I'm running a fully loaded Start One from the Start9 people.
So far so good; small, quiet, unobtrusive...
I haven't actually measured the power draw yet, though I suspect it's pretty reasonable?
