That would be one thing not seen in any of the photos there. After looking at several vendors the best was seen at http://www.svc.com/cl-w0076.html
The problem however was there was no option to buy the clip needed for the AM2 model boards. Before ordering you will want to see how the HSF normally mounts on that model board. The specifications apply to all K8 and Intell 775. K8 refers to Socket 754 and 939 model boards.
The K8 is the type of cpu(central processing unit) installed on the system board. The coolant itself is not meant to be replaced but sealed air/water tight. Someone that uses a water cooling system would have a better idea of how long the level of cooling liquid lasts before any is needed.
Having some extra onhand is one thing that would be wise to have around in the event any leaks develop. That's the one drawback some have seen with this type not particular brand of cooling method. Most of the time taking the time to "Follow directions" will see good results. Just take a little extra when installing the system if you do end up buying it.
The main concern before ordering this is to find someone running an AM2 board that has tried this cooling system. The information say Intel Socket 775 and AMD all K8 which means K8 Version
