Which case? The store i work for ordered a bunch of shelving from them a couple months back (i did the order) so i've got a reasonable idea of what they're stuffs like. We sell NES games too so that might make it easier.
Can't say i have personal experience with these. Like Radjago said, i'd assume you'd need to modify the tabs inside, seems like the width would be ok, just have to monkey with the height.
