Reactor PC

It's one thing to have a liquid-cooling heatsink, but it's quite another to have your entire computer submerged in coolant. The Reactor PC ($4,550 and up) offers first-of-its-kind submersion technology to allow for the most reliable, most efficient overclocking around. Features include 7.1 digital surround sound, Intel Core 2 Extreme quad-core processors running at up to 3.2 GHz, up to 8GB of DDR3 RAM, 3 SATA connectors, an Nvidia 790I Ultra SLI chipset and up to three video cards, and a great-looking, blue-lit translucent case. Game on. [Thanks, Steven]
