Cooler Master has done it again. Not only have they impressed with their new high-end Cosmos, but also with the mainstream RC-690. The case has a lot of very useful features and additions which are usually not found in cases which cost less than 100 US Dollars or more. The only downside is the optical drive installation, which is not completely screwless. The engineering within the case is ingenious for such a price range, as simple additions like the clips to route cables or screws placed inside the case, are very useful features. You even have the choice to get the RC-690 with a side window for an additional 5 €, to show off that clean cable management and your hardware at a LAN party.
