That looks amazing - my home-made heatsink looked like an absolute pig! (Mainly because I had to sand out the cavity for the driver with a blunt dremel head!) My new blu-ray build will be using a nicely made heatsink (still home-made though) in a large pocket-sized host. Good luck finding the GGW-H20L - I've been searching for a long time.
