The only workstation that boots with entirely free software is like, the Talos II PowerPC, with a minimum cost of $5000.
Everyone else requires a binary blob somewhere. Either a UEFI blob, BIOS blob, some kind of driver somewhere, or whatnot. Raspberry Pi, AMD, Intel, everybody.
And before the Talos II, I don't think an "Open PC" devoid of proprietary binary blobs even existed. At least, something that is reasonably modern (ie: 64-bit, decent security, decent support with modern OSes)
