Hacker Phame has taken a low powered Raspberry Pi mini PC, which is available to purchase for around $35, and added a pimped up cooling system creating a water cooled Raspberry Pi mini computer.
To re-cap the Raspberry Pi mini computer which is manufactured in Wales, UK, is equipped with a a 700 MHz ARM11 processor, which can safely be overclock it to 1 GHz if desired.
If you would like to go even higher than that you might then nee to think about upgrading to something similar to the water cooled Raspberry Pi version created by Phame.
The water cooled Raspberry Pi took a few months to build and uses neon-pink water pumped to three of the hottest points on the Raspberry Pi board. The cooling water pumps on the Raspberry Pi draw their power directly from the board, so only a single power adapter id required to drive the system.
