Taking a look at the front of the case, the Obsidian 650D displays its brushed aluminum faceplate, four 5.25" bays, stealthed I/O panel, power and reset buttons, and a large front vent. The brushed aluminum looks great and is very sleek. The case stands on what I'll call an oval loop, kind of reminding me of a Power Mac G5 — only less pronounced. The left side of the case shows the quick-disconnect side panel with about a half-size window, cleanly framed by a sharp, beveled edge. Through the window, I can see the wire management passages on the motherboard tray, along with what looks like a massive CPU mounting access hole. This is something that I specifically ask of manufacturers often, as it's not uncommon to find a case without an appropriately-located hole to allow full access to the mounting area. All it takes is making it big enough to encompass a larger area to accommodate more motherboards. The rear of the case shows the 120mm exhaust fan, I/O bracket, eight expansion slots, bottom-mounted PSU bracket, and two water cooling grommets. There is also a passageway to pass a USB3.0 connector through the top-left corner of the rear if needed. The right side of the case is identical to the windowed side, simply lacking the window — though it still features the quick-disconnect hardware. So far, the look of the Corsair Obsidian 650D appeases me. It has an elegant, sleek, and stylish look.
The top of the Obsidian 650D houses a large 200mm exhaust fan, with 2x120 and 2x140 compatibility, as well as the door leading to the hard drive dock. It features the same black textured paint as the rest of the case and there's not much else to it. The bottom of the case shows the wide feet that span the width of the case, holes for the adjustable PSU stabilizer, and a removable fan filter. The fan filter easily slides out of the rear of the case, right below the power supply mounting bracket. There is also a rubber pad on each corner of the front and rear feet, helping to alleviate noise transference from the case to its resting surface.
At the top of the front of the case is a spring loaded door, that when pressed, flips open and exposes the I/O ports. The Obsidian 650D boasts quite a collection here and is probably the widest variety of ports that I've seen, as it includes just about all standard ones with the exception of eSATA. Behind this door are two USB3.0 ports, two USB2.0 ports, audio jacks, and a Firewire port. I have seen very few cases that offer front Firewire capability. Of course, 98% of us won't use it, but the 2% that do will be very happy about it. That's just Corsair covering all its bases. Right behind the I/O ports on the top is the hard drive dock. It will accept 3.5" and 2.5" drives. For 2.5" drives, there is even a spring-loaded tab that holds it in place. For 3.5" drives, this tab is simply pushed down beneath it. Inside of the hard drive dock is a very small, hardly noticeable fan controller — a 3-speed, 4-channel controller to power the three included fans. I almost missed it because of how small it is!
On the front bezel is the fan filter for the front 200mm intake fan, which is easily removed by pressing the top edge, opening just like the I/O port does. It is a plastic frame with plastic mesh, easily washed and replaced in minutes. Removing the front bezel entirely is also simple and doesn't require a lot of effort. There are six tabs holding it onto the rest of the chassis. Once they are released, it pops out with a little bit of leverage on the bezel. Behind the bezel we can see the fan and the perforations for the airflow path leading to the hard drive area, along with the four toolless 5.25" bays. Luckily, since the I/O area and power button/LED are part of the chassis, the front bezel separates completely and doesn't have the headache of potentially popping wires out of PCBs if the wires are too short (which has happened to me before). That's just another example of the clear thinking Corsair exhibits in its cases.
Now that I've shared the exterior of the case along with its features, it's time to move on to the interior of the case, where I'll cover an in-depth evaluation of the working components and its internal features.
