Over on Phoronix, folks seem to have been much more excited about the Talos II by Raptor Computing Systems. They come with IBM POWER9 CPUs.
"The Talos™ II mainboard is the first modern (post-2013), owner-controllable, workstation- and enterprise-class mainboard. Built around the brand-new IBM POWER9 processor, and leveraging Linux and OpenPOWER™ technology, Talos™ II allows you to secure your data without sacrificing performance. Designed with a fully owner-controlled CPU domain, you can audit and modify any portion of the open source firmware on the Talos™ II mainboard, all the way down to the CPU microcode. This is an unprecedented level of access for any modern workstation- or enterprise-class machine, and one that is increasingly needed to assure safety and compliance with new regulations, such as the EU's GDPR. "
People claim to want open hardware and the security you get from not being forced to trust a variety of companies. But then when it's time to put their money down suddenly freedom is too expensive. This is exactly why we've arrived in this position in the first place.
Talos is following the Tesla Master Plan. You can't afford a Tesla Roadster? That's fine, the people who can will buy it, that covers the R&D and the next model will be cheaper.
Talos machines are large workstations. Much of the System 76 business, and much of the "daily computing" is now laptops. I don't think a laptop with a Power9 would make sense, even if the system could be crammed into a laptop-ish case.

While also not 100% open, it sounds like a lot more important bits are.
The Talos machines sure are pricey though.
