You may opt to unsolder the frayed wire at this step and solder directly to the circut board. I even recomend using aftermarket wire here because the mac wire is quite lame.

I chose to cut, strip, clean, and tin the existing wires on both sides of the joint.

Tape or use heat shrink tubing on this joint. Remember not to leave too much extra wire around the joint because we are going to stuff it all into the case before closing it up.

You may opt to super glue epoxy your case shut. I just snapped it back as well as possible and gave it a healthy dose of electrical tape in case I ever need to check on my solder joints. I also tightly wrapped about and 1.5" of wire to the body of the brick to act as a strain relief.
