I received an order with upgrade parts for my mini PC yesterday. I started installing them and then noticed that parts of the FrostFlow 120 appear to be missing. In particular, the back plate and countersink nuts appear to be missing. I've included a photo. The Frostflow package included the plate around the cooler, the posts and the thumb screws. However, there was no back plate or countersink nuts. I am unable to attach it to the motherboard.
