This was a slow water leak that led to a large ice sheet building up under the center draw so it took a while to diagnose the source of the leak. Once I had it narrowed down to the filter or the filter head I took the filter case apart to see if the repair was doable.
For somebody with average skills it was not that difficult once you removed the crisper drawers and shelf to get to the filter case.
The filter case itself has 2 screws and 7 or 8 plastic clips on the top and bottom holding it together. Take your time and all will come apart, note that there is a cold water bottle in the filter case as well, that's why there are 4 plastic hoses coming out of it and only two with the new filter head.
The blue hose from the filter head just fits, length wise, so be sure to seat everything in place before making the connection to the input valve.
I did discover the cause of the leak as a hairline crack in the old filter head, Samsung does not warranty this part after 1 year.
AppliancePartsPros had the part shipped to me the next day.
Great service.
