It's probably a stupid suggestion for many reasons, but somehow I imagine having a single cover piece that folds over the top and halfway down the back side would at least look cohesive as that would be a fully perforated piece. Then the part that sits behind the mobo and psu is solid. I was going to suggest that the base (where the stand attaches for vertical orientation) could instead be part of this mobo mounting part as well, but now that seems impossible (or at least unreasonably difficult) given that the front and back of the case are already folded from that piece.The only practical advantages of this idea would be the ability to remove the cover without removing the stand first, which is pretty minor, and maybe easier access to the GPU. I also suspect that I would be in the minority in thinking that a seam on one side of the case would look good, but there we go.
