Size and weight detail
Size and weight detail	The exact maker sheet labels height as 47.5 cm, width 20.6 cm and depth 51.1 cm. Earlier G5 sheets label height/depth in the opposite order; main dimensions are omitted because those published axes conflict. Maker reference weight is 20.2 kg and varies with configuration.	Maker height 51.1 cm, width 20.6 cm, depth 47.5 cm. Published reference weight for the single 1.8 GHz model is 16.4 kg, distinct from the carryover dual-processor models; weight varies with configuration.

In the box
In the box	Mac OS X Tiger and iLife ’05. Apple’s 27 April 2005 launch says these models are available “this week”; first sale is kept at April precision rather than treating the announcement as a confirmed delivery day. The older single 1.8 GHz model retained in the launch range is represented separately as Late 2004.	The October 2004 release includes Mac OS X Panther and iLife ’04. Apple’s retained specification sheet later lists iLife ’05; that later software listing does not change the hardware’s October 2004 first sale.
