Hi!
I know this is a really, really old topic. But I wanted to let you all know that I have done it. I had a GTX 960 100 ME with an ugly green color scheme. I believe it's the same with 960/970 models.
Here is the finished product:

Here's the inside of it:

At first when I opened it up, I saw a see though MSI logo printed on a paper (sort of). Peeling that off, gave me a small piece of glass with an SMD LED soldered INSIDE the glass. Soldering another LED into the glass is extremely difficult. (Piece of Glass:

So, here's what I did:
-I bought a 12 volt 3258 LED strip with 60 LEDs/M, so one segment (LED strips can be cut at certain distances i.e segments) would fit perfectly inside the cavity where the LED and the glass would go, previously.
-I cut the end of the GPU LED's wire to procure the 2 pin plug which would plug into the card (you don't have to, if you can find one of that size). Soldered that plug into a longer piece of wire and then the wire to the LED strip. Put the completed LED strip with wire into the cavity, and plugged it into the card.
-That's it. Assembled the card back and boom! It was working. MSI Gaming App/Geforce Experience LED Visualizer can control the animation and brightness as well, much to my wonder.
Tbh, I didn't think it'll work and was planning to connect the strip to a molex so that I can use my PSU's power instead of the card.. but! it worked!
