"The real issue for the release of the 700D was that pricing again took them out of many buyers' lists. At that time the 800D, fully loaded, was near $300, and the 700D missing the key features that set the 800D on such a pedestal, and the pricing was only $30 less. While I liked both chassis', I don't think Corsair hit the "heartstring" of the average buyers, at least not yet.
Almost a year to date since I looked at the 700D, the Obsidian series gets a new addition. Keeping with the same exterior simplicity and styling, this new chassis holds a new interior in a new case type as well. Both of the previous chassis designs were based off of a full tower design, where this time the 650D we are going to be taking a look at today is based off of a mid tower design. With the success of another mid tower, the 600T from the Graphite Series, Corsair thought it a great idea to reuse the interior with this design. Not only should it keep pricing down, since there isn't a vast redesign trying to take away from the 800's interior, it offers you the best of both series in my opinion."
