I am aware of System 76, but I am not sure their hardware offerings are good value for money. I could be wrong, but that's why I'm asking this question!
Actually I've heard bad things about their hardware in that if you ever try to deviate from the officially supported distros you're going to have a hard time finding drivers. That's all second hand so take it with a grain of salt.
I wasn't impressed with my System76. It's fine, but no different than a beefy Dell.
A lot of these manufacturers resell the same laptop hardware from one specific Chinese company. The hardware is pretty rubbish. Stick to well known brands that can get repaired easy like Dell & Apple.
I think I have heard it called Clevo, for that particular company in the past, I don't know if that is still true.
