The oldest tech I have are laptops from 2006, 2008 and 2009, a pc from ~2010 and an android phone from around 2012. I also have lots of newer stuff.
I’ve already built a home server from the most suitable pc. What other real use cases for old tech would you suggest? What is your experience?
If you already have one home server, you need two more to make a redundant cluster.
And then you need another set of three to live at a family member or friend’s house to receive your off-site backups.
