Build and Finished Product
The mounting screws were installed as per the instructions by sliding a nylon washer on the screw and passing it through the motherboard. Aside from having to keep the wrench in the end of these screws, all the rest of the mounting is done up top.
We added thermal paste to the CPU and set the block on top of it with the Intel steel bracket lying on the rim of the CPU block. On each screw, you drop a nylon washer down it and screw down the nuts to lock them to the motherboard. Then, set the block down, add a steel washer, the spring, and tighten the thumbscrews in an X pattern.
Before we put the motherboard back into the D-Frame, we did add the compression fittings to make life a little easier as we contemplate how to install this loop into this chassis.
We went with a top mounted radiator position, which actually ends up being run as if it were hung off the back of a chassis as well as being laid on its side. This was just the best place with access to the fittings and the fill port on the UT60.
Since the D-Frame lacks a dual 5.25-inch bay, we made it fit where the HDDs should go by strapping it to the fan frame and adding some foam to isolate the pump from making things rattle down there. We also added a pair of ninety-degree fittings to the back of the reservoir to make life easy with the tubing runs.
