These days computers are replaced after the 3-year service warranty in many companies, we would just toss them to the recyclers (or the back of my car sometimes if I had a project happening at home…) Occasionally they would find second use somewhere reliability didn’t matter, but a lot of IT managers won’t risk it, production downtime for a $700 PC is not worth it. My last job in a factory I had to get written permission from an IT manager to redeploy an out-of-warranty system, or could be fired when it failed.
