If you've been noticing more reviews of ECS products (and getting quite good scores at the same time) you're not mistaken. After merging with PC Chips, ECS has recently started pushing into the retail market; prior to that, they have been one of the largest OEM manufacturers for more than a few brands.
They recently took the opportunity to bring some websites on a tour of their factory-in-the-making. At this huge factory that will eventually employ 8000 people, they can make motherboards from PCB to final product. We also talk a bit about the working conditions at ECS and China in general.
