All the computers I've owned and used are still in working condition, except for one. The oldest ones all have had their hard drives replaced, the oldest desktops all had GPU upgrades. Upgrade one, and shift the rest down the line. Only a few machines got RAM upgrades. One dead GPU got replaced on my previous PC. A dead PSU was replaced on my current machine with one from the PC that I'm not fixing. The dead PC was also a donor for upgrading two laptops to SSD, it only has the broken main board with CPU left in there. I also repair my headphones whenever needed using spare parts from broken ones of the same model. It's enjoyable to keep things working.
