Bought this brand new for a custom waterloop but ended up not working on the project anymore. Box has been opened and the block had been placed on the CPU but it has not been used or has had any fluid go through it so it's still like new. My box in particular also had two of the same bags for some screws that are to be used for LGA 1700 and was missing the AM5 screws. I bought the AM5 upgrade kit for the screws and so those will also be included.
