Revised list of example systems, with corrections, price estimates, citations.

Coreboot with all components open source; fully removed management engine:
* Lenovo X200/T400/T500 w/ Coreboot, CPU: T9600 (dual core, each core about 50% 
of a modern i7-7920HQ [2]). Max 8 GB RAM. Cost: 75 USD used.[4] These systems 
run Intel Core 2 Duo CPUs, which lack EPT [5], so don't meet Qubes 4.x minimum 
requirements.

Coreboot with open source RAM init but some minor blobs; partially removed 
management engine:
* Lenovo T530 w/ Coreboot. CPU: i7-3840QM (quad-core, each core about 80% of a 
modern i7-7920HQ core [2]). Max 16GB RAM. Cost: 300 USD, used. [4]
* Lenovo W530 w/ Coreboot. Not officially supported, but someone made it work. 
Max 32 GB RAM.

Coreboot with proprietary RAM init; partially removed management engine
* Purism Librem 15. CPU: i7-6500U (dual core, each-core about 80% of i7-7920HQ 
[2]). Max 16GB RAM. Cost: 2000 USD new.[3]
* Purism Librem 13. CPU: i5-6200U (dual core, each core about 70% of i7-7920HQ 
[2]). Max 16GB RAM. Cost: 1700 USD new. [3]

For a list of blobs included in Coreboot, see [1].

All the Lenovo systems above require manual Coreboot compiling and an external 
flasher. The Purism systems can be flashed with coreboot from software (maybe 
only certain laptop revisions?) and can be preinstalled with Qubes.
