I did put it together myself. I even have a few cords loose from the case haha so they are probably the problem. For the most part I did a good job, I got everything to fit and work nicely. The wires left over are labeled HD audio (my brother in law said you needed a sound card for that, I personally don't know) then there is the restart button (I plugged this into every available spot on my mobo and it never worked but honestly I would never use it even if I could so I don't care about it). As for the HD audio wire I really don't think there are any places I can put it. I looked for a very long time and couldn't find the correct spot for it.
