History: The iMac (Summer 2001) represented a minor change to the existing iMac line, and represented a shift back to a more conservative color-scheme. The 500 MHz model, with 128 MB of RAM and a 20 GB hard drive was $999 U.S., and was available in Indigo and Snow. The 600 MHz model, with 256 MB of RAM and a 40 GB hard drive, was $1,299, and was available in Graphite and Snow. Finally the 700 MHz model, with 256 MB of RAM and a 60 GB hard drive was $1,499 U.S., and was available in Graphite and Snow. A low-end $799 U.S. configuration was later added, with a 500 MHz processor, 64 MB of RAM, a 20 GB hard drive, and a CD-ROM drive, and was available only in Indigo.
