Well , this is a case !

The original Cosmos was a terrible design. A huge shell with no thought given to airflow paths, so cooling was poor. As it was an obvious turkey, CM soon released a revised version... but the mere fact that they could put out something like that in the first place cost them all credibility with me. OTOH, I am pretty happy with the CM-690 I bought back then. It all means that with anything CM - wait for the reviews. They can do good work and they can produce junk.
