I have an 8gb Raspberry Pi 4 that has been a workhorse for years. I keep it for my not intense but essential networking purposes, NetBoot.xyz, Homepage, etc., because I can run it over PoE (edit: Power over Ethernet), so it is always on as long as my network is up.
It is growing long in the tooth, and I find myself wanting to replace it with something a bit more capable. Looking at the 8gb Pi 5 at $80 plus another $30 for a PoE hat, I wonder if there is something out there that would be a better value for running PoE? Can you convert a micro pc over to PoE? Does anyone have any recommendations for computers that run off PoE or can be converted to PoE?

I’m open-source; check me out at GitHub.
I actually didn’t know the Pi can do PoE; that gives me some ideas!
You need a hat for it.
Ugh now even my Pi needs clothes??!? Ridiculous.
I have a cluster of four running all off a single switch, incredibly convenient.
What’s PoE?
Path of Exile.
Power over Ethernet. Sorry, read it over three time for spelling, didn’t catch that I never gave the acronym meaning.
I can’t believe someone downvoted you for asking about the acronym.
I get frustrated when the title, body, and comments all use an acronym, but I can’t figure it out from context. Even more frustrating is when the linked article also doesn’t explain it.
I think googling poe or poe computing will give you it
MINISFORUM S100-N100 launching later this year as efficient mini-PC with Power over Ethernet support
I bought an N100 mini PC (not POE) as my new server a couple months ago. I really like it. That processor is great for power efficiency.
Personally I am a fan of the soquartz blades
But I doubt one of those is more powerful than a pi. I run a cluster of them with k3s and distributed nvme storage, but that may not be useful for your particular needs.
I have three Raspberry Pi 4 4gb and 1 Pi 4 8gb at my disposal, and I still have moments where the thing I need to do will hiccup, or be slower than usual. The Pi 5 has been said to be two times as fast, which is plenty for me. just with the price all in of over $100, curious if anyone else has a better option/opinion
What things do you do that hiccup?
It honestly reallt depends whether your task is hindered by storage speed (sd card), io speed (lan + usb ports), single core speed or lack of threads/cache. It would be good to find out what the limiting resource is, to understand the best upgrade path.
Webpage loads are slow, especially images, netboot is a bit slow. I’m sure it’s i/o bottleneck and that everything is running in docker containers. I could probably optimize things a bit better, I just don’t have that kind of time for these projects, and getting an old dell micro would be faster than what I have. but they don’t run on PoE+ that I know of.
I think pi 5 might be pretty good for you.
If I am not mistaken, they improved the io A LOT in the pi 5.
Also, you might be able to use the old HAT, at least it worked with pi3 poe hats on pi4.
… they don’t run on PoE+…
They do not; the power requirement is too high. You’re not going to find a computer with a “desktop class” CPU that can be powered via PoE.
I would be interested in this as well. The Pi certainly works and I am running one POE. But the Pi can be very limiting.
If you are converting something, be aware PoE has a power budget of 15w and PoE+ has 30w. Though PoE++ can do 100w, I have not seen many switches with that.
PoE++ is 60W, UPoE is 100W.
PoE++ Type 4 goes up to 100w, its Type 3 that goes to 60w. Why the hell they didnt just call it PoE+++ I’ll never understand
