Apple Macintosh Performa 5420CDThe Apple Macintosh Performa 5420CD, based on the Alchemy architecture, features a 120 MHz PowerPC 603e processor, 16 MB of RAM, a 1.6 GB hard drive and a 4X CD-ROM drive in an ultracool black all-in-one case with a 15" shadow mask color monitor.

The Performa 5420CD is identical to the Performa 5410CD, but the 5420CD was packed in a black case, which made it one of only a few black all-in-one Macs. This model was sold in Europe and Asia, but unfortunately, never was sold in North America.
