OpenCompute look interesting on the surface, but it seems like the "server owners" listed at https://www.opencompute.org/sp/open-compute-project-solution... consists of mostly larger corporations.

Appears to mostly be an enterprise offering; I'm not quite sure if any of these companies would sell me a server for personal use. And even then I don't think I'd be able to request control over the various keys they're in control of (ie request the work be done to get me keypairs of my own, which I do think is theoretically possible).

Hmph.
