Packard Bell's Designer Tower, which uses the well-recognized "Frog Design" design, was introduced around late 1995 and included models like the Legend 1824CDT. As evidenced by the Force 1998CDT, Designer Towers existed as early as August 1995.
The Designer Tower includes a single 3.5" floppy drive and, most commonly, a single CD-ROM drive - leaving two empty 5.25" drive bays. Sometimes, it is seen with two CD-ROM drives or a single CD-ROM drive and a 100MB Zip drive.
This case was used for Packard Bell's higher end designs such as the Platinum/Platinum Pro series. Occasionally, some Multimedia or Legend/Legend Supreme models are Designer Tower cases, but this is rare.
