I got a start in upgrading 7 donated laptops. 4 are done. GNU/Linux Mint with Xfce desktop installed in about 30 minutes per computer. Another 10-15 minutes to run updates. Specs: 4 to 8GB of memory, hard drives (rather than SSDs). Instead of being recycled they are ready for continued use. Totally usable for day-to-day general use. Anyone can do this kind of direct action, community mutual aid that conserves energy and resources.
