Dual-Processor, Liquid-Cooled Power Mac G5s Announced

Apple today announced a new line of Power Mac G5 desktop computers, featuring dual PowerPC G5 processors in each model. The top-of-the-line dual 2.5 GHz model ($3,000) sports a new liquid cooling system, circulating liquid past the G5 processors and through a radiant grille, where the liquid is cooled by air flowing through one of the Mac’s four thermal zones. Mac OS X dynamically adjusts the flow of the cooling fluid and the speed of the fans based on the temperature. A dual 2.0 GHz G5 retails for $2,500, and the entry-level model, featuring two 1.8 GHz G5 processors, starts at $2,000. These models, featuring NVIDIA GeForceFX 5200 Ultra video cards, are available immediately, and the high-end, liquid-cooled dual 2.5 GHz model with an ATI Radeon 9600 XT graphics card, will be available in July. Apple has also ended production on the 1.25 GHz Power Mac G4; remaining units will be available for $1,300 while supplies last.
