I just read an article in Tech edge about water cooled PC's. So I thought some info would be useful. (Actually I first thought this was a good idea before I saw the article, but i never tried for fear of shorting my motherboard.) Water cooling allows one to get more out of their PC, not alot more, but still more power from the processor. Also water cooling just sounds cooler and looks cooler then fans and heat sinks. The latest system on the market is Innovatek's Eheim's 1046, for sale for $225. Anyway they are for sale at www.highspeedpc.com/ Now you can really start overclocking on that ol' P4.
