Cooler Master has produced some wildly popular case designs, and a frequent favorite amongst budget builders is the CM 690. Now the case has been revamped and looks forward to its public debut come January 2010 at CES.

The CM 690 II Advanced showed up on our forum’s courtesy of a not so cleverly disguised Cooler Master rep. who has given us a sneak peak of both the CM 690 II and Advanced version of chassis.  They incorporate much of the same style as the first gen. but according to the Cooler Master representative, the cases feature  ”brand new bodies that aren’t based on the CM 690 or any other extant chassis”. While the exterior is similar in size, the interior has been expanded to allow for better cable management and more “innovative features”.

The case will be shown off at CES 2010, but for now, Cooler Master has hosted a teaser site with a countdown clock until release, and posted a few taunting photos of the exterior.
