Sorry for the late respond, If you purchase 2 seperate size distros/backplates you can expand the case to these 2 sizes.Also, apologies for the double post, i just got really excited about the case fite me. The gap in the seen when the case is in full extra large mode i assume will be covered by the side panels/glass upon expansion?
Because of the size of the base height of the case, when you expand it to the maximum, there will be little gaps in the sides. I can cover it, but when you close the case, there will be smaller sideventilation. If this bothers you, I will cover it.
