Nice work, pit bull - interesting choice with the thick spacers/cold plates. How are temperatures with those installed? That's a pretty thick piece of copper on there...

Also, for your mounting - it looks like you had to drill out the corners of the backplate a bit to make space for the screw stack - is this true, or did you use an alternate solution? Also, how is the spacing between the two screws for the danger den block? Did they align correctly to the 4870X2's mounting holes without any binding against the sides of the holes?
