Install your M2 heatsets into the plug. Use a soldering iron to gently heat the brass heatsets. While still hot, use a Popsicle stick to hold the heatset in place, so it remains flush with the surface of the plug.

Plug the connector into the back of your mac. You can use a flathead to push each connector onto each blade of the plug. Then, fill the voids in behind each conductor with hot glue. This will keep the conductors in the right position for future insertion and removal of the plug.


Fill in the rest of the triangular void in the back of the plug with hot glue, encasing the wires in that area. Reply 2 years ago. I guess if you had read the beginning of the instructable, you'd have noticed that I wasn't about to pay the price people ask for this odd style cable.

The only problem is that can't use the PSU cover, but that's okay. I don't want to cut it, as I'm planning to use a picopsu from mini-box.

    I have a similar setup in my HTPC, and it works great. Just like in that project, the powerbrick will be inside the case. The finished computer in its environment: Thanks for following.
