PoE Single Board/Micro/Mini Computer/Server

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?

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.
- https://en.m.wikipedia.org/wiki/Power_over_Ethernet
- 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
- power over Ethernet
- Power over Ethernet. it essentially combines the power plug with the ethernet cable. super helpful for stuff like network cameras where the nearest wall socket is 50 feet away.

  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.
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.
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++ 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
