This Power Mac 5500/225 would be perfect for a Collector
The unit powers up & works fine (see pictures). I could not get the CD to open to test it (not sure if there is one in it).
This unit is dated April 1998.
Power Mac 5500/225 Specs
The Apple Power Macintosh 5500/225, based on the Gazelle architecture, features a 225 MHz PowerPC 603e processor, 32 MB of RAM, a 2.0 GB hard drive, and 2D/3D graphics acceleration in an attractive all-in-one case with a 15" colour monitor. Originally, this model was sold only to the North American education market, but Apple finally realized that many people not in education also would like an all-in-one model and released it to the consumer market as well.
