I acquired an ewaste laptop with a 5+ year old Celeron, 4GM of RAM and a spinning rust drive. I tossed mint on there after fighting with Windows update to try to apply 3 years worth of updates and while the installer took 2 hours to complete, it actually is a bit more usable and once it's booted it's amusingly chirpy with random slowdowns whenever it has to hit the disc for data.

I might set it up as my daughter's first computer. She's getting to that age already so it's about time to do it
