damn, this casing really puts down my antec p180b really bad lol, and just for an additional rm200 or so.

and ive really been very fond of acoustic casings with proper dust filtering systems, this really fits my needs. good review too man, looking forward to see your thermal review on the case, as the antec dont fare too well on the thermal department.

most likely your ES (as the name implies) is an early revision or even a prototype of the cosmos thats on retail right now.
