Another successful OpenBSD setup
I’ve been buying these little boxes from AliExpress for years to use as firewalls and routers. My oldest one is almost 9 years old now! OpenBSD installs just fine. Just a BIOS tweak to always boot up after power is restored.

Only on port so you can’t use it as a router unfortunately
