iBuyPower have decided that the only difference between a laptop and a desktop is the size of the strap needed to carry it. Behold the LAN Warrior.
The specs are pretty impressive too, 1000W power supply, five fans, Intel Core i7 Quadcore 3.2Ghz processor, 12Gb RAM and twin ATI Radeon HD 4870X2 2Gb running in Crossfire mode; $US3280 as configured here. There are tonnes of different configuration combinations available including space for two dual slot cards in Crossfire mode, liquid cooling and 24Gb of RAM. It all sounds very impressive, but I just like how it has a strap so you can carry it easily.
With the iBuyPower LAN Warrior, we have designed a system to redefine the limitations of SFF systems. The LAN Warrior is capable of running the latest technology with no compromises in terms of expandability, power, or cooling.
