In considering a custom build, should I avoid certain manufacturers or products? As I have no interest in Windows, I’ll be using purely Linux distros. Still, I wonder if there’s hardware privacy concerns that I may be unaware of as most of the world seems to be in regards to services such as Google and Facebook.
I depends on your threat model and ethical standards.
But generally any modern computer running linux is fine.
I mean sure you have things like intel ME and the sorts, but those are not threats an normal person needs to worry about in the slightest.
