Yes, the Odroid H series SBC probably come closest to OP's requirements. Schematics are available on their website. They are also really low power with even the older H2 idling below 4 W.

I use an Odroid H2 which is an amd64 SBC with two Ethernet ports, two DIMM slots but only two onboard SATA ports. There’s a PCIE slot though.
The new version H3 has a slightly more powerful CPU but is otherwise the same. www.odroid.nl/H3-Plus

Thanks for your reply. Honestly what I’m asking for does not really exist. You have to pick from features, open source and hackyness. Usually you can get 2 of the 3 but it’s hard to get all three. So although I wouldn’t buy this PC, it’s a pretty good recommendation for stumbling on this post in the future.
