You’re very welcome 
Every computer has it’s own downsides. That being said, there are some computers that are known to work better than others with Qubes.
Novacustom laptops are very promising. 
-
They offer very powerful laptops.
-
Based in the Netherlands, so delivery should be very quick.
-
They provide Open source firmware with the Dasharo/Coreboot UEFI on some models like the NS70 Series
-
They ship some laptops (NS51 Series) with the CSME =(Intel management Engine) disabled.
They seems to be honest, they don’t pretend to do what they can’t do. Wessel klein
(NovaCustom Ceo) seems to be a nice guy
Keep in mind that I haven’t bought any of their laptop, so my recommendation are only based on others reviews. One of my friend bought the NS70 laptop that he received withing 3 days, and he’s very happy with it. (He is not running Qubes Os tough!)
Also you should know that some kind of human being change their behaviors, policies when they see millions of dollars in front of them. 
That’s an important information to keep in mind.
My top recommendation would be ThinkPads, known for their exceptional robustness, Linux/Qubes Os compatibility and durability. 
-
The powerful Lenovo ThinkPad P51 which is part of the community-recommended list
-
The Lenovo ThinkPad T480 which has a good history working with Qubes Os.

There’s no need to buy your computer from a “Privacy” company to have a private computer.
You may also be interested in the new Qubes-certified Desktop which I ordered the last month but still not delivered. 
I hope that those recommendations will help you find what’s best for you. You should do your own research as you’re the only one that know what you’ll do with your computer. 
Don’t solely rely on opinions from strangers on the internet, like me.
