The "slot" measurement is notoriously inaccurate. Every manufacturer measures it differently. We use it more as a general guideline.
The measurement that we ere with in terms of compatibility is the actual width measurement. The console is compatible with cards up-to 40mm wide. The card used in the photos is the Strix 1070, which comes in right at the 40mm mark!
I think part of the inconsistency comes from whether the manufacturer includes the rear thickness due to a backplate.
Can Console accept thicker card if the side panel is not used - or it might be blocked by some other elements of the case?
