Yes, you can get cheaper laptops. Whether they are "equivalent" is a matter of what you consider "equivalent". Certainly you can get Clevo from other sources at a lower price. They just don't come with the same enduring Linux support, let alone niceties like coreboot, etc.
Which Dell XPS with equivalent specs at 15 inch screen is cheaper let alone considerably cheaper? I can't seem to find on the Dell website https://www.dell.com/en-us/shop/dell-laptops/sr/laptops/xps-...
Gets even worse with 32 Gigs RAM- the cheapest Dell XPS is ~$500 more that this machine specced out to 32GB RAM https://www.dell.com/en-us/shop/dell-laptops/sr/laptops/xps-...
