BenchmarkReviews.com: The Obsidian 650D is Corsairs second attempt at a mid-tower case and the third case in the Obsidian line that started with the 800D almost two years ago. The 650D was created in response to the two biggest complaints about the 800D, which were price and size. Priced at $199 and now in a mid-tower design both issues have been addressed. At the same time the 650D has retained many of the same great features and aesthetics that made the Obsidian 800D so popular. While evaluating the Obsidian 650D Benchmark Reviews will see if it is worth of the Obsidian moniker it has inherited or if many of the features its older brother had have been lost in the transition to a smaller size.
