Grand daughter is rocking a customer cast off laptop. I was asked for help when the first lock down for covid was announced in the UK. I slapped on Kubuntu and an OpenVPN connection back to my home pfSense router on it, so I could manage it. All a bit slapdash but best I could do at the time.
That was 2020. Six months ago, I find out she is still using it and its a "bit slow". I update it from 18.04 to 24.04 via ssh over an OpenVPN connection on the box itself. Its still in use and is still attached to both one of my home OpenVPN servers and my work Mesh Central.
I've also recently repurposed another Win10 but can't do Win11 laptop to someone so they can do some courses.
I think I'm doing all right with supporting the next cool kids.
I'm still stressing though 8)
