So how would you go about creating a smaller case of an already excellent one and diversify your case line-up at the same time? Ask Corsair. They have not only managed to impress with the Graphite 600T (which is also available in white!), but have ported the great feature set found within that case and infused it into a new chassis worthy of the Obsidian name tag. The extra features, looks and quality give the Obsidian 650D plenty of unique aspects, while the shared use of the case internals should keep the price lower. For anyone eying with a 700D or 800D, but wanting something smaller, the Obsidian 650D is it. Let me repeat myself: it will be interesting to see, if Corsair ever chooses to bring out a sub 100 USD chassis in the future, but regardless of that - the new Obsidian 650D is a logical step in the right direction to diversify their high-end line-up of cases and can easily follow in the footsteps of its bigger brethren as well as other case manufacturers out there. The only downside is the small difference in price between the Graphite 600T and the Obsidian 650D, which may mean that Corsair is cannibalizing its own market.
