So, I have no idea what I'm doing, but I had this old HP zBook lying around (the thing is from 2014 I think?) with 32gb of RAM and a 1tb SSD in it, just doing nothing.So I installed linux mint and was like... ok, now what? It's too heavy and awkward to use as a daily-use laptop. Then I remembered NextCloud and was like - yeah, I wonder if I could host my own NextCloud and use this machine instead of Google Docs/Google Drive? And NextCloud can do a bunch of other stuff too...So I found two other 1tb thunderbolt drives that I wasn't actually using, and plugged those in. I also already had a non-managed 2.5gb ethernet switch for my work computer's connection (it needs to be ethernet - I need the speed)...So now I have a pretty respectable hardware setup.... but no idea how to get it all to work.I know, I know, I could just go to the Linux Mint forums and ask people for step-by-step instructions (which I feel like could be a disaster for me). Or I could read a book. Or I could do any numbe...
