Looking for low power devices for selfhosting (lemmy.world)

Hi friends. I'm a newbie in self-hosting, though I've been managing (virtual) linux servers at work for a couple of years. I'm completely ignorant on the hardware choices out there, hopefully you can point me to the right direction.

Here are my requisites:

Low power consumption, I plan to have it connected 24/7 and I'm kinda concerned on how much it will impact the electricity bill
Ethernet port, preferably gigabit but whatever
Graphical performance is not important as I don't plan to connect it to any display. As long as I can ssh into it, I'm good.

Services I plan on installing, for starters:

casaOS
pi-hole, or equivalent
Home Assistant
Kitchen Owl (nice to have)
Paperless-ngx (nice to have)

I live in europe and my budget is around 80 euros or so. Thanks in advance!

Bonus: there is a literally endless supply of used x86 SFF hardware from large institutions, so unlike SBC's, there's no special, weird supply chain managed by an English educational nonprofit that could just suddenly decide to not sell to the public for years at a time.

could you please elaborate? what is SFF hardware?

[–] [email protected] 2 points 10 months ago

SFF = Small Form Factor. It's smaller than traditional ATX computers but can still take the same RAM, processors and disks. Motherboards and power supplies tend to be nonstandard however. Idle power consumptions are usually very good.

USFF = Ultra Small Form Factor. Typically a laptop chipset + CPU in a small box with an external power supply. Somewhat comparable with SBCs like Raspberry Pis. Very good idle power consumption, but less powerful than SFF (and/or louder due to smaller cooler) and often don't have space for standard disks.

SBC = Single Board Computer.

Hi, sorry I just saw this. "SFF" is short for "small form factor." It's just industry jargon for "a small PC." They tend to be designed to use less power which makes them a good fit for home servers. Pretty much any line of PC sold to businesses, like Dell Optiplex or HP EliteDesk, will have small form factor variants.
