A:AnswerI'm not really sure. According to a few different sources, the 2000 series cards have been discontinued, which may be why a lot of them on Amazon are absurdly priced. I hope this is restocked soon as it's the perfect part for my build and I need it. My advice would be to check E-Bay, as they often have people selling preowned cards that look brand new. Sometimes, if you're lucky, you can find a brand new and sealed card for the MSRP price ($499). I hope this helped!
A:AnswerThe only limiting factor would be space. The Aurora R6 comes in configurations that include full-sized graphics cards such as 1080ti (or in SLI). I imagine a full sized card such as the 2070S would fit, but you can measure the length.
