Just looked at that, not that one, they used the corsair prebuilt: https://www.corsair.com/us/en/Categories/Products/Systems/Vengeance-PC/VENGEANCE-PC-6100-Series/p/CS-9030008-NA
I remember seeing this from them
I am having issues with finding the Linus Tech Tips video with them demonstrating how a corsair prebuilt computer (I believe the AMD prebuilt) where they show you it is easy to load MacOS as well as Windows OS making it into a dual boot system. Does anyone have the link for that?
Edit: I believe it was in the year 2020 towards the beginning of the year.
