I love this community, I used to rant about efficiency all the the time on reddits self hosting community and everyone thought I was insane. If the damn thing is going to run 24/7 for 5+ years then put a little thought into its power usage!
I personally love old Dell optiplex micros on eBay. Cheap, plentiful laptop hardware in a cute little box which allows modest upgrades. My primary server in a full sized case is just a laptop CPU, Ryzen 5600g. It brings me joy that my network has four servers and still is under 75w idle for everything including networking gear.
Wild to see this posted. I worked for the guy that invented this at Sylvania, I have a bunch of photos of the early prototypes. They never figured out how to commercialize it and in the process of trying to manufacturer it in China the manufacturer stole the IP and started making them under their own brand and stole the market. They were called Icetron lamps. I worked in their R&D facilities and domestic manufacturing sites in the early 2000s.
