Cmon, go look for the NanoPi M4 - released in 2018 - had PCIe. Just because you’re stuck in the Raspberry Pi money grab doesn’t meant there aren’t other things out there.
Let that sink in 😂 the NanoPi had PCIe since 2018… and if you want to OG, then the SheevaPlug has gigabit Ethernet in 2009, before the Pi existed.
