If you are providing a compatible ethernet board as in this writeup, virtually anything you can actually plug the board into will work.

Have a look at Odyssey by Seeed Studio, I got one for NAS. J4105, 2x Intel NICs, 8GB RAM and DC jack. Pretty good value after erasing Win10.

Pc engines boards are suitable as routers.

Any other ASRock Mini ITX board will do. I'm running FreeBSD router on J3455M, works flawlessly.

Check out the PC Engines APU2. They work very well with OpenBSD. I've been using them for ~8 years.

I'm not sure how they would handle a gigabit. I have 250Mbps and I get 248Mbps with a dozen firewall rules.

I've been running an APU3A4 on a gigabit for the last 3 years. Works just fine.
