I am looking at getting a fractal desigm north xl second hand, I presume there is no danger in that other than standard non new concerns.

Then I see no issues with an AMD Card. There are some edge cases I know about where nVidia seems more suitable due to their drivers/software support. But to be honest, I don’t do high end gaming, so there could be things that nVidia generally does better than AMD, independently from linux.
