Just a quick note here:
I was doing some measurements on my own system and I noticed something interesting. Though you may already know this, I figured it was worthwhile to share. All of Zavar’s measurements lined up on my 9570 except for the top right spring-loaded screw, and the gem-shaped cutout next to it. On my motherboard, there is no top right screw hole, but instead a MOSFET (I think that’s what it is anyway) in its place. There’s also one less of the black rectangular component with a plus-sign in parentheses on it (sorry, I don’t know what it is) near the top-rightmost motherboard mount.
After looking into this further, I found that there are actually different motherboards in the 9570 based on whether it was made earlier or later in the year last year. The difference is clear between these two images.
