We had to wait quite a while before the Corsair Obsidian 900D was released, but it's finally here and it was definitely worth the wait. From the get-go we say that this has been an intriguing experience. This is an extremely well built and sturdy super tower chassis, and despite its size it simply is a well thought through product. Heck, the sheer weight alone is already impressive. The 900D obviously is an advancement of the 800D and it does manage to advance in multiple ways. One of the more discussed 'issues' with the 800D was the secondary lower compartment for the PSU blocking a bit of airflow. Personally I never have found that to be a massive issue, but regardless, in the 900D this has been redesigned from top to bottom. Basically there are still two compartments, but they remain open. Not a difficult thing to understand as you can reach the two compartments really easily by opening up the lower doors / latches.
The looks then; well that's always subjective as heck of course. Being a Guru3D reader you probably like if not love the design. I must admit that when you look at a photo of the chassis, you could end up a little puzzled and unsure about its aesthetics but trust me when I say that once you see the 900D for real and not in a photo, then it all starts to make sense. Now if I may be a tad more subjective, personally I feel the aesthetics are just awesome. It's a clean cut matte black finish looking chassis. It is black from the inside out. It's perfect for dark-colored high-end gear like motherboards and graphics cards and the side panel window will definitely show you all the goods you install combined with the lower compartment doors that can be removed and transformed into fan intakes. The design is very tasteful, not screaming with logos and flickering LEDs, subtle... that's the word I was looking for.
Then there's the sheer amount of details and features that Corsair put into this chassis. The removable HDD/SDD trays, the many grommet holes with rubber inlays for managing your wiring, then spacious wire management options on the backside of the PC itself with hinges that you can tuck the cabling behind, it just oozes space. Now I don't think I mentioned this already; the chassis was developed with a codename, "Godzilla", haha. So yes it's big alright, this case measures 655mm x 694mm x 251mm. You cannot look at the 900D without realizing it can hold ATX, E-ATX, XL-ATX and HP-ATX motherboards compatibility wise. Then there is the four 5.25" drive bays, a whopping nine 2.5/3.5" bays and ten PCI expansion slots. Cooling capacity of this case is just not an issue and a nice detail is the dust filters with a magnetic mounting system. For the liquid cooling fanatics, they can fit multiple radiators in the chassis including 480 mm and a 360 mm radiator inside, without the need for any modifications. We have rarely seen so many details available to us overall. The 900D is ready for whatever you'd like to throw at and in it.
Sure, there always is something, this is an expensive chassis and as such you should get it all. I am nagging I know but I would have liked to see some sort of fan controller. I really feel that is a bit of a miss. Also just two USB 3.0 ports are a little on the shy side, four would have gotten my preference. And then perhaps maybe a memory card reader? And the last thing that comes to mind would have been some sort of HDD/SSD mounting dock where you can quickly insert and connect a storage unit. I know, this is all nitpicking stuff, but yeah these came to mind yet I do realize these are all more or less personal preferences.
Alright, let's wrap things up. We think the Corsair Obsidian 900D is a very unique and terrific product. It won't be for everybody though, as the price level will scare quite a few of you miles away. We expect the product to retail just over 300 USD and just under 300 EUR. Once you have spent the money then things fall into place, the sheer weight alone will reveal that. The shipping costs to move the product to location must be a huge factor all by itself. Unboxing, once you start, all of a sudden becomes this weird surreal experience and once you've removed all the plastic protection you'll stare at the chassis with a smile on your face. It is one of the most versatile and coolest looking chassis' to date. Whether you want to install a small form factor motherboard or go huge with XL-ATX and HP-ATX it simply is all possible. Two PSUs? Sure, not an issue. The fans aren't silent, but not noisy either yet offer a nice steady airflow inside the chassis, cooling down your high-end gear, and that's a very important aspect alright. Wiring? You tuck it away with the convenient cable routing options. HDDs you simply slide in and then once you've gone through the basics, you start to wonder why on earth you did not opt for water-cooling. And once you start with your LCS kits you'll notice there are mounts everywhere making this chassis very flexible to use whilst you do not have to mod stuff, it won't get any handier than this. Summed up, the Obsidian 900D really is all about great aesthetics whilst having a chassis that has no limitations whatsoever. It has fantastic build quality and oozes craftsmanship.
The design combined with its features and looks make this a very recommendable product to opt for or at the very least think about if you need something like this. So yeah, in closing... the looks are fantastic and the amount of space you get to work with is downright serious, everything inside that chassis somehow makes sense and is balanced out, it's equilibrium -- yeah it really is a super tower chassis.
