The inside of the Obsidian 650D is a lot like its bigger brother which is a great thing. Starting at the front of the chassis, we find four toolless 5 1/4" drive bays. There is a huge bundle of wires above the top bay coming from the front I/O panel. Fortunately there is plenty of length on these cables so they can be routed behind the mainboard. The cables are black in color so they won't stand out like a sore thumb.

Below the optical bays are two toolless HDD cages, each supporting three drives. Each bay is SSD ready and if you need more room for a very long video card, the top bay can be relocated to the floor of the case just beside the power supply. Or if you don't need as many storage drive bays, you can remove the cage to increase airflow from the front intake fan.

Looking at the rear of the case we can see cutouts to run the rear fan wire as well as the front USB 3.0 cables. The rear 120mm exhaust fan is also positioned here, as is the 200mm fan up top.

As we mentioned earlier, there are eight expansion bays and two water cooling tubing holes in addition to the power supply mounting area at the bottom of the case. The expansion slot covers are all reusable via thumbscrews and are slotted for better ventilation. Corsair includes a bracket inside the case that can help position the PSU, but this is something that I ultimately removed as I didn't see much use for it in my install.

Corsair has once again done a great job with strategically placing holes in the motherboard to route cables. The cable slots are lined with grommets so your cables won't become shredded by sharp edges. Additionally there is a large gap behind the motherboard tray to route and store unused cables. Many cases have very little gap here which means the right side panel won't fit on if there are too many cables behind the board tray.

The aluminum front bezel is removable, although it takes a good bit of force to do so. Once off, the 200mm intake fan is visible as well as the expansion bays and the bare front I/O panel.

Let's move ahead and get some hardware installed in the 650D.
