If you like the all-in-one design of the iMac desktop but need more power than entry-level units offer, this enhanced model may be right for you. It includes a PowerPC G3 chip running at 600 MHz, 256 MB of RAM (expandable to a gigabyte), and a 40 GB hard disk drive. That's big enough to store thousands of MP3 music files, for example--and the included CD-RW drive makes it easy to burn your own CDs. A 56K modem and 100 Mbps networking are standard. The system's integrated case design, in a translucent gray that Apple calls "graphite," houses a 15-inch monitor with 13.8-inch viewable area. The system comes with both the classic Mac OS 9 and the slick new Mac OS X installed.
