I used one of the Koolance HD waterblocks in my early days (it was their first Water cooled case, a total PoS). All I succeeded in doing was killing my drive. I can't imagine a setup where you would ever need to cool your HD with a waterblock. It's trivial to provide more than adequate air cooling for HD's in almost any case and even keep that cooling below audible levels if your are concerned about sound. In my experience water cooling HD's is a waste of time, money, space, and adds unnecessary complexity to the system.
