Why would you remove the motherboard? Just lay the case on its side and be careful not to pour super glue all over!
I don't have a picture but the layout has two rows of three connectors that are stacked vertically. Another mistake I probably made was to add connectors sequentially so I have an entire row (sata 1 - 3) filled with cables. With the connectors stacked vertically, all the space between them is so jumbled it's hard to see the plastic headers let alone where the headers hit the board. This is partly why all the connectors were roughed up by me - when I go to pinch one with my fingers I am pushing / bending at least one other one because the gap between the connectors cannot fit the cables and my fingers (and I have small hands).
It would be nice if the connectors were stacked horizontally. Or if the cables allowed you to pinch them from the sides. But pinching from top/bottom and stacking vertically makes it hard for a clutz like me.
Live and learn I guess. Hopefully I won't make this mistake on my next build (trying to wait for the next Intel cpu due 1st quarter).
