I am in need of a desktop PC made only of Free and Open hardware components.
If I could be sure that such a thing is possible, I'd even be willing to build it myself; however, I can find no guides on Google on how to determine if this motherboard is open, or if that adapter released its firmware source.
I'm particularly interested in hardware that does not impede my ability to install my own firmware. Open hardware schematics are not necessarily a requirement.
How would you go about accomplishing this task?
