The company is offering a model previously available only outside the United States.
It is the first Macintosh announcement from Apple since yesterday's news that the company is buying the core operations of clone maker Power Computing.
The Power Macintosh 8600/250, with an estimated retail price of U.S. $3200, is part of Apple's new lineup of desktop computers for professional publishers, media/Internet authors, academics, and science and engineering professionals, the company said in a prepared statement.
The 8600/250 orginally debuted at Macworld Boston in early August.
Like the other new Power Macintosh 9600 and 8600 models, the Power Macintosh 8600/250 includes several performance improvements, such as a new PowerPC 604e processor with "Inline Cache" technology to boost the performance of the 604e, Apple's new Mac OS 8 operating system, a 24X CD-ROM drive, and a 4GB hard drive.
The Power Macintosh 8600/250 also has 32MB of memory standard.
