Read the motherboard manual carefully. The ECS manual is fairly clear but assumes you pretty much know all the terminology, and doesn't fuss with detail. It does have clear motherboard diagrams though. The case LED/switch connectors weren't described particulary clearly, but we'll get to that later. Inside the box is 1x floppy ribbon cable and 1x IDE ribbon cable, plus a CD containing drivers and some other not-incredibly-useful stuff.
