You connect the power switch and hdd cables to the front panel header. This is labeled as '12' in your manual and is immediately to the right of the '11' you plugged the power led to. If you whip it out, you will find a detailed diagram of this header and where to connect the power switch and hdd cables.
I see that now, how did i miss that. Okay, got them all connnected now, working on the power cables now. Cant wait to boot it up. Hopefully I did everything right.
