Just google a YouTube video on how to open... I used electrical pliers and the supply popped open with NO damage at all to the case. It took about 2 mins to open 1 min to soldered the new cable in and 5 mins to put the case back together correctly and super glue and clamp the case for drying. The soldering is easy if you have basic experience. Suggest testing before you glue up... but really this is hard to mess up and it will work and look like brand new for a fraction of the price of a new power supply.

My experience is that it is the cable ends that go first. Right at the mag safe or where it enters the power supply. The replacement cable can be purchased for $6. For that price, it is worth the effort to repair.
