For my Proxmox Homeserver I use a Fujitsu D3417 with a Xeon E3-1225 v5. Pretty "old" Hardware, but it is 9.3 Watts IDLE with Samsung 980 Pro NVMe and 64GB ECC RAM after doing only small optimizations (powertop, etc.). I'm not sure why Intel / Fujitsu does not share these (or more modern hardware) for the "consumer market", but for my personal use case it is a pretty impressive system. There is a forum user `m.gutt` using the Corsair RX550 with a Gigabyte C246M-WU2 Mainboard running (best case) 6.65W [1] My Router is now a Banana Pi BPI-R3 with OpenWRT drawing 4.3 Watts idle (I only ordered it, because the GL.inet MT6000 was not available now) and I think the Intel System is on another level, although it cannot really be compared because of the network stuff...

When did efficiency started to matter with home servers? It feels like chasing the high perfmance/w ratio is a recent thing that is becoming more popular, or maybe I'm just out of the loop. I'm not hating btw, just curious.

  Electricity prices are rising in Europe for at least the last 10-15 years (which accelerated since 2022). The higher rates the more people care about power consumption.

  Like the sibling comment said, electricity prices are going up. We're getting peaks of 40c/kWh here. In addition summers are getting hotter and extra energy usage in hardware is translated directly to extra heat. I need to run my AC more in the summer because my tiny server rack is producing so much heat. During winters it's kinda handy though =)

  When electricity price went up 3 orders of magnitude.

  It is not only about efficiency, but also about these so called MiniPCs (N100, Raspberry, Rockchip, etc.) being sold for > 100 bucks these days and with a little effort you can build a REAL server with ECC and NVMe based on older used hardware for only a little more money with ECC RAM, similar efficiency, way more power, cool remote features like AMT / ILO and better OS / Software support due to x64 architecture. I think the whole "Raspberry as a home server" discussion is pretty much overrated since the prices went up, because nowadays it always seems to be a compromise in terms of price / performance.
