I am not sure if this is normal, I have already installed the plate on the back as well as the bolts on the top (whatever they are called). I am in the process of installing the X Bracket, (Bracket shaped like an X). I lined it up with all of the holes but it seems that I have to apply A LOT of force to make the screws on the bracket go down into the holes and then so I can screw them. Whats wrong, I saw in some youtube videos that there was barely any tension for them? Does this have to do with that screw in the X bracket thats in the middle? I read around that the screw adds weight to the processor, I havent touched it yet but should I loosen it? Thanks.
