This is meant to hold all 7 SW dvd's (6 movies plus bonus features dvd)
Here's another set that holds the 7 dvd's.
This is a set of four cases that line up to form a single image. The four cases are:
1)The Original Trilogy case can hold up to 8 of the myriad bootleg DVDs (in 4 double Amaray) that are out there for the OT, which include different transfers of the films with different special features, the classic documentaries, etc.
2)The Prequels Trilogy, will hold the three 2-DVD sets (once ROTS comes out), plus a custom 2-DVD case designed to hold the "Clone Wars" series (once both of those discs come out).
3)The Special Edition Trilogy, is for the official release -- Episodes IV-VI, plus the Bonus Material DVD.
4)The Saga Continues case can house the Ewok movies, the Ewok and Droids animated specials, R2-D2 Beneath The Dome, etc.
These boxes are quite pricey. I plan on getting the set of four cases soon. Here's a link if you want to see where to get them: DVD Cases
