About a year and a half ago, we got our hands dirty picking apart Corsair's first stab at the whole "computer case" thing: the Obsidian Series 800D. Then, last September, we brought in the newer and more affordable Graphite Series 600T for a similar run around the ol' test track. Today, we're going to be looking at the Obsidian Series 650D, which melds the 800D's externals and the 600T's internals with an asking price smack in the middle between the two.

We were impressed with Corsair's first two designs, so we're eager to see if the 650D manages to bring the best of both worlds without breaking the bank. At least on paper, this puppy looks like a potentially great middle ground for folks who don't care for the 600T's rounded, somewhat chunky design yet can't afford to spend $280 on an Obsidian Series 800D. Also, I think I heard something about getting a free sub with a drink after doing three Corsair case reviews.

As you can see below, the 650D has much in common with the 800D visually—it's tall, rectangular, made of steel and aluminum, and outfitted with a window on the side. Where the 24" x 24" x 9" Obsidian Series 800D towers above mere mortals, though, the 650D is a little more manageable, measuring 20.5" in height and 21.5" in depth.

To make room, Corsair has ditched the hot-swappable hard-drive bays and replaced them with a single Serial ATA dock situated at the top. The good news is that there are still six internal 3.5" bays—so, in effect, the 650D has one more hard drive bay than the 800D. Corsair has done away with one of the 5.25" external bays, however, so users with lots of optical drives (or miscellaneous control panels and third-party fan controllers) may be disappointed. Then again, four 5.25" bays is still plenty.

Speaking of fan controllers, the 650D has one of those built in. It lets you adjust the three included fans (200 mm front, 200 mm top, and 120 mm rear) between low, medium, and high speed settings.

The 650D uses the same dual-latch locking system as the 600T for the two side panels. Also, as with the 600T, the panels don't slide in horizontally; they swing out vertically when unlocked. To put them back in place, simply align the bottom of the panel with the hinge at the base of the case and swing the panel in place. I much prefer that system to the traditional sliding mechanism, since it involves less effort and makes it much easier to tuck in unwieldy cables.
