Depends on the input your PC needs. If it’s a common 19V power supply then you need a 19V PoE splitter like this + an adapter for whatever connector yours has: https://www.ebay.com/itm/194028107173
You’ll also need a switch that can supply 802.3bt PoE.
The usefulness of running a mini PC off of PoE seems pretty small, but there are some cases where it might make sense.
PoE can go up to 70W according to wikipedia. A few years ago, a cheap NUC would draw ~50W with heavy loads. And they would have probably been more capable than a Pi5, GPIO excluded (and you can add this to anything with USB. You might even be able to do something with a low-speed M2 port.)
Can I run a mini-pc via PoE?
Sure, just need a PoE adapter for it.
Which one specifically?

Ok, so what PoE splitter do I use?
You want me to do your shopping list?
You made the post without bringing receipts.
It’s like asking “how do I bake a chocolate cake” and you said “go get ingredients from the store”. Not helpful.
PoE splitters exist
