Actually, no - their thing for the past few years has been to build out the most comprehensive test bench across all PC hardware components. "LTT Labs." They are aiming to become the authority on hardware performance and reliability, and have invested heavily in the tools and industry experts required to do that. Linus doesn't do any testing himself; he is just bankrolling it with the proceeds from his main channel and other media properties.

I find this whole thing super fascinating, coming from the perspective of Silicon Valley startups.
