iMac (Summer 2001)

iMac (Summer 2001)

Compared with the iMac (Early 2001), this base model has a faster 500 MHz G3 processor, ATI Rage 128 Ultra graphics, 128 MB of memory and a 20 GB hard drive. A CD-RW drive replaced the CD-ROM drive. It came in Indigo or Snow and shipped with Mac OS X installed beside Mac OS 9. A later, lower-priced version has a CD-ROM drive instead.
