Size and weight detailExact Japanese maker sheet publishes 43.2 cm height, 22.6 cm width, 46.7 cm depth and 13.6 kg weight; configuration-dependent.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.
Power supplyMaximum continuous power 200 W.450 W on dual 2/2.3 GHz; 600 W on dual 2.7 GHz, as stated by the maker.
Materials–Aluminium enclosure.
In the boxMac OS 8.6 originally. September 1999 introduction and a few original 450 MHz channel shipments are documented by Apple-History, but the first shipping month is not established; release stays at year precision. February 2000 maker release confirms immediate availability of the revised range.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.
