Moot issue. As I understand it from discussion on the Other Site, the OP procured a Gigabyte 3060 and is going with that. 

FWIW, I like the idea, nakamuram, but I would stay far away from those particular computers. The cases don't breathe, run hot, and fans are loud. Good thermal performance is vital to the longevity of the components, and you won't find it there. After investigating pre-builts for months, I gave up and picked parts. If one must buy pre-built, a Newegg ABS model can be a good choice. Others tend to be too expensive or too compromised for consideration.
