I bought all the stuff (new case, networking card and a Jonsbro N4 to repurpose some intel i7-9700 era processor and motherboard, but didn't get it setup yet, as I was starting to rethink the power consumption....
Also looking to use this rebuild as an opportunity to learn Nix.
Let me know if you all have some good article references, to point me at. I've been doing some research, but could always do more.
I may end up putting a low power NUC in the case, or something. I don't know...
