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!
Risking sounding like a broken record, I always suggest Tiny/Mini/Micro 1L form factor office PCs. Lenovo, Dell, and HP all create ultra small office PCs that make great low power servers. A Pi will use 5-9w at idle, while these PCs will use 11-13w idle. They also use more standard components such as NVME drives, 2.5" drives, and replaceable RAM. Easy to find under $100 USD used, I’m sure you can find them under 100 euro.
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?
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.
We buy the HP Pro/Elitedesk 1L pcs as backup servers and attach storage.
Works pretty good and they are pretty cheap with the power they can provide.
Good point.
The Pi Zero is 2w max… It’s downside is it draws 2w MAX. Power is power, only so much you can do in 2w. As you pointed out, the 4 and 5 can do more, because they can draw more, (or they draw more so can do more, it’s all related).
The key seems to be ability to minimize the idle power while still capable of ramping up to something useful when you need it - like the micros you’ve listed.
