Wow! is thing heavy. Not cheap aluminum but solid. Anyone have this or no someone that does. I saw it at Fry's the other day and thought about it. With a little goo between the two it would really keep the 7200 rpm cooler and be great for when 10,000 is standard in the not to distant future.. Kinda $$ though, $40.00..
