So it looks like I might have access to an old hardware project from work.

11 of these odroids H2+ which aperantly are just x86 SBCs: https://www.hardkernel.com/shop/odroid-h2plus/

They are all wired up, are connected with a switch, power management, nvmes, etc. and attracted to a piece of wood.

What would you build and do with that?

Go nuts!
