Hi,
maybe use openwrt, it’s meant by to be used on cheap low end devices, don’t know how good the image is. https://github.com/Kazagumo/openwrt-orangepizero2
I personally use it on an discontinued WD mybook live duo. If you prefer an easy setup, be warned, it is not. ;) On the plus side, openwrts Luci is a good starting point for configuring of a lot of services, hdd spin down, monitoring, etc.
Use case: samba4, kopia destination from my VPS through Zerotier
Good luck with your setup!
So did I and also one of the few subs. 🥹
