The unit gets its name from its "ROG Poseidon" graphics card, which sports an Nvidia GTX 700 GPU and Asus' proprietary hybrid "DirectCU H2O" cooling system. DirectCU H2O combines multi-directional "CoolTech" air-cooling with liquid-cooling systems to reduce the GPU's operating temperature by as much as 31 degrees Celsius, or nearly 88 degrees Fahrenheit.
That graphics card is plugged into Asus' "ROG Maximus VI Formula" motherboard, a unit that comes equipped with its own fancily-named hybrid cooling technology: "CrossChill," a system that combines heatsinks and liquid cooling. The motherboard also includes a "SupremeFX" onboard audio card, which can pump out jams through a 600 ohm headphone amplifier shielded for electromagnetic interference.
No word yet on when the rig will be available, what it will cost or what processor/HDD/SDD/RAM configurations will be offered.
