uuuuuh... if you are talking about dvd cases, get some official amaray cases (cause they are great) and get a double sided tray insert. for 4 disc games, i personally just use some double sided tape and ad a second tray behind the manual. but you can get 4, 5, and six disc regular size cases. downside is they are almost exclusivly black, so if you want the ps2 blue, or like me want all cleear cases its a little trickier
