In my opinion the up to date cases for playstation/xbox/ and gamcube, are the most durable, as sega cd used the same cases as sega saturn, i have very many of the and i can only pick out one or two that don't have scratchs cracks, the peice the hold the front on isn't broke off, same thing with the original playstation cases, not very durable, i feel more safe using the newer cases, even wene I take my sega cd games somewere i always take it out off the original case and put it into a playstation 2 case.
