ECS is a familiar name to many as a company that has been manufacturing low cost motherboards since 1987.  Since their inception, ECS has expanded from just motherboards into offering barebone and complete systems, laptops, and even servers.  
  
 
Although they still have strong a focus on motherboards, they have not always received praise from the computer enthusiast segment.  ECS is trying to change that with the release of their new flagship motherboard, the KN1 SLI Extreme.  On paper it has the makings of a very solid motherboard that could help you move into a SLI configuration at a lower cost than the bulk of the competition.  This review will take a closer look at the KN1 SLI Extreme and see whether it has the ability to compete with other mainstream enthusiast motherboards.
