I think part of the inconsistency comes from whether the manufacturer includes the rear thickness due to a backplate.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!
Can Console accept thicker card if the side panel is not used - or it might be blocked by some other elements of the case?
