The OLED is larger in size so I doubt it’s a direct replacement.

Bigger battery. From 40mah to 50mah.

I just name them based on the case labels, model name, and/or server function. My main host server is “DellPVE”, gaming computer is “Phanteks”, Plex server named “Plex”, octoprint is named “Octoprint” etc…

I agree with this. Get some quotes and if you can afford it then have a professional do the runs. Pulling wire through existing walls is a pain and then add in crawling through the attic.

I paid about 1200 to have 10 Ethernet lines ran; 8 poe for security and 2 data lines to my computer work area. I think it was worth it so I didn’t have to crawl though my hot itchy attic lol
