USB 3.1 gen 2 on a G5 Hackintosh

Hi,

I'm doing a G5 Hackintosh and was wondering exactly how to add 'real' USB 3. Since I couldn't find much about it, I started this guide. I'm not there yet but I'll complete it as we go! :)

So this is the front I/O of a 2008 G5 Mac Pro:

I figured out that you can easily pry off the metal back, unplug the power button and unscrew the tiny front I/O board:

Now the question is: how to I replace the USB 2 connector with a USB 3.1 gen 2 connector? /u/GFlunk has done it before so I ask him to chime in with some details :) Just remove the old one and hot glue a fresh USB-3-connector-to-motherboard cable in?

How did you guys do it?
