Last week Apple Computer, Inc. introduced its most powerful Power Mac model to date, which sports two 2.5GHz G5 processors and a nifty liquid cooling system (LCS). Curiosity surrounding the new LCS is running high as Apple officials have recently reiterated warnings that other G5 products from the company remain a long-shot due to G5 heat issues.
Aiding some of the curiosity, sources have recently provided AppleInsider with side and rear-view diagrams of the new Apple LCS, which detail some of its many components.

In a recently published self-training course on the new line of Power Mac G5 computers, Apple confirms that all models feature IBM's 970FX PowerPC G5 processor.
"Power Mac G5 (June 2004) models use the PowerPC 970FX processor. Previous Power Mac G5 models used the PowerPC 970. Compared to the 970, the 970FX has a smaller die, higher speeds, and has been optimized more for higher performance."
The dual 2.5 GHz Power Mac G5 model, which is the only model to utilize the liquid cooling system, will begin shipping from Apple in July.
