How about idea top side motherboard access plate - same with bottom side. I saw many people they cut top plate to install higher cooler.
The point of the bottom access panel is for the ease of maintenance. Making a case promoted as small as console just to install a cooler that is standing out of the case outline defeats the point.
Also adding the same thing on both sides isn't something that would help the looks. If we were to do that, we'd rather have to make such panel above the GPU, and making one above the motherboard would completely break the looks of perforation on this side.
