ThinkComputers: Corsair really surprised us when they entered the case market with the Obsidian Series 800D full tower case. The 800D was just awesome and probably one of the best cases I have reviewed in the past 3 years. They next went to the Graphite Series with the 600T, this case was equally impressive. Today we are taking a look at the first mid tower case in the Obidian Series, the 650D. The case has many of the same features we loved on on the 800D, but also adds some from the Graphite Series line of cases as well. Is this the perfect mid tower for you? Read on to find out!
