Cooler Master keeps improving and modifying their already superior products to the point that the term "New and Improved" actually means something other than just being a marketing ploy.
I keep thinking about the absence of a top exhaust fan and my good buddy Ron Golden of amdmb.com fame suggested that Cooler Master might be gearing up for the next generation of CPU's (like AMD's Hammer) which will run much cooler than their predecessors and are expected to be released shortly. Makes sense to me!!
But in closing, let me say that I've never been disappointed with a Cooler Master Aluminum Case and I'm sure, neither will you!!
