Because I checked and rechecked all the connections myself, there isn't too many things to connect in this build any way.Why don't you take a high res picture of your MB and connections for us so we can help you with this?
You're right, I didn't explain the layout properly at all. I knew this but I figured maybe my description was good enough...I'm not certain but I think from your description you have connected the wrong power and reset button plugs to the System Panel Connection on the Motherboard. Looking at the manual (from the Asus site) and to use your nomenclature .. the first row has one pin, the second row is the Reset and the Power Button Ground, the third row is the Reset Ground and the Power button. That is, the reset and power button connectors should be connected thus:
Row 1: Blank One Pin (nothing)
Row 2: Power Grd Reset +
Row 3: Power + Reset Grd
Row 4: Power Led - HD Led -
Row 5: Power Led + HD Led +
With the LED connectors from the case, I'd look for the + and - and connect them to the appropriate pins on the MB and not worry about the spare plug.
Yeah, that's exactly what the wire is like.I even looked up the Lian Li manual, but that is rubbish (nothing about the front connectors at all). So the Power led connector (plug) is 2 wires going into a long plug (with a gap between the + and -)? I don't know why they do these things.
I think I'd leave that until you get the computer running. Once it is working (ie: you don't need to return anything), I'd just cut the plug in between the wires and put them where the MB wants them.
