For a brief time on Thursday night, Apple Computer Inc. reportedly
posted information on its Web site detailing the company's next
generation computer, known as the G5. While the information has since
been removed, the company wasn't quick enough as Mac enthusiasts and
Web sites across the Web captured images of the pages.

The specs posted to the company's Web site list the G5 as being
available in three speeds: 1.6GHz, 1.8GHz and a dual 2GHz with up to a
1GHz processor bus; up to 8GB of DDR SDRAM; Fast Serial ATA hard
drives; AGP 8X Pro graphics options from Nvidia or ATI; three PCI or
PCI-X expansion slots; three USB 2.0 ports; one FireWire 800 and two
FireWire 400 ports; and optical and analog audio in and out.

The machines will reportedly also be Bluetooth and AirPort Extreme
ready when they ship to consumers.

A new desktop machine based on IBM's 970 processor was anticipated
during company CEO Steve Jobs' opening keynote of Apple's Worldwide
Developers Conference . The conference opens Monday June 23 with Jobs
addressing developers and press at 10:00 am.

Originally slated for May 19-23, 2003 in San Jose, the conference was
moved to June 23-27 at the Moscone Center in San Francisco in order to
provide developers with a more complete preview release of Panther, the
next major release of Mac OS X.

Contacted by MacCentral, Apple had no comment.
