The iMac G5 is an all in one desktop computer designed and built by Apple Inc. from 2004 to 2006. It was the final iMac to use a PowerPC processor, making it the last model that could natively run Mac OS 9 (Classic) applications. It was replaced in 2006 by the Intel iMac.

As a result of Apple's new turn toward Intel processors, the first iMacs were the basis of the Intel Core Duo processor at 1.83 GHz and 2.0 GHz, accompanied by the ATI Radeon X1600 graphics processor, from a screen of 17 Or 20-inch and 512-MB RAM (extendable up to 2 GB)

The equipment had 60 bytes of RAM, and was used to calculate how much water was spent in the state.
