How is the water-block designed?

The water-block comes with pipes already attached:

The water-block’s base is covered with film to protect it during transportation and is ideally finished. In the next photograph it like a mirror reflects a part of the plate for mounting the water-block on AMD K8 processors.

The water-block is fully made of copper and is not composite, so we don’t know much about its internal design. They only say that the water-block is made using the micro-channels technology.
