There's the need to dust fans and then there's the possibility that OS computing requirements have risen which isn't often a Linux thing on old hardware.. OsX had exactly the same problem and had to make a minimizing release IIRC.
Computing kind of stagnated since 2010 and plenty of hardware since then still works fine today and is usable enough for many tasks. Apple was nice for needing not all that many different drivers but its statnge integrations like drive fans to bios are obnoxious.
I'm not really sure that's remarkable, maybe compared to the netbook level machines. Now that HDs are gone the only cause of failure I see from my coworkers is extended vacations and remote work in tropical climates.
