The Fusion Elemental uses a unique liquid metal cooling technology designed in Denmark to allow clock speeds previously only available with exotic water cooled or phase change PCs. A unique electromagnetic pump circulates the liquid metal completely noiselessly and moves heat from your CPU into a sophisticated pipe and tower heat sink for effective removal by two ultra-quiet 120mm fans. The rest of the system is no less formidable. A Core i7 overclocked to 4GHz is coupled to Asus' flagship motherboard with USB 3.0 and SATA 6GBps technology, whilst a solid state storage drive and 1TB of conventional storage means you'll never run out of space. The Elemental is a spectacular gaming machine thanks to your choice of one or two Radeon HD5870 video cards, whilst top quality Corsair RAM and a Corsair PSU rounds off the specification. This system comes fully installed with Windows 7 Home Premium 64bit as standard!
