A couple of months ago we looked at Cooler Masters Cosmos 1000 case, a high end model in every way. From the size to the design, to the performance, the Cosmos excelled. The only downside to this product was the high premium, so it immediately rules out a large portion of the enthusiast market. All is not lost however, as Cooler Masters CM 690 (RC-690) is priced at a more affordable £50/$80. The 690 manages to pack in some excellent features with a well thought out design.
