KS6615 Terminal 15 Inch, Celeron 1.0G, 512MB RAM and WindowsXP Pro) The new Posiflex Fan-free KS Terminal is the model of heat transfer efficiency! The ultra-thin aluminum chassis design leverages the heat conductivity of metal, which is much better than air cooled systems. The significant increase in the surface area which dissipates heat eliminates the need for fans, thus improving long-term durability. Additional benefits of the revolutionary fan-free design include quiet operation, less moving parts, lower power consumption and easy maintenance. The Posiflex KS is the new standard of durability. The black color further enhances the space saving, spill proof design Posiflex is renowned for. There is also a stunning 17 inch version. The industry has been looking for the next generation of ingenuity and cutting-edge technology. The wait is over!
