The Obsidian Series: Designed by Builders, for Builders.
Obsidian Series 900D is for serious builders with big projects. Do you want to design your ultimate dream PC? Add state-of-the-art liquid cooling or air cooling? Build a quadruple GPU, dual CPU graphics powerhouse? Or, just create a monster file server?
If these are the kinds of questions you’re asking yourself, you need a 900D.
Serious Expansion Flexibility for Serious Builders
We don’t need to tell you that there’s no such thing as too much room. We’ll just let the numbers speak for themselves:
- Ten expansion slots.
- Fits up to nine hard drives or SSDs, with three hot-swap mounts.
- Four 5.25” optical drive bays.
- Room for dual power supplies.
And if nine hard drives or SSDs aren’t enough, you can expand to 15 drives by adding additional drive cages (available separately).
Incredible Cooling Performance and Potential
A cooling-optimized case design requires three things: good passive ventilation, flexible fan mounting options for good airflow, and the room to add sophisticated active cooling systems. The Obsidian Series 900D starts with a clear airflow path from the intake fans to the case interior, with no drives in the way. But, that’s just the start.
- Includes three AF120L 120mm front intake fans and one AF140L 140mm rear exhaust fan.
- 15 total fan mount locations.
- Five radiator mounting points.
- Four removable dust filters.
Easy to Build with. Easy to Live with.
System builds should be straightforward and easy, without your PC case getting in the way. And, reconfigurations and upgrades should be just as simple. An enjoyable build process with great-looking results is a huge part of the pride of ownership that comes with building high-performance PCs.
The 900D can help make it all happen with tool-free side panel access, hard drive installation, and optical drive installation. Inside, you’ll find a CPU backplate cutout and rubber grommets on the cable routing holes. There’s generous cable routing space behind the motherboard tray, and snap-down cable latches help you create clean, easy-to-modify cabling that doesn’t rely on dozens of zip ties.
You also get modular hard drive cages, and the dust filters and fan covers are easily removable for cleaning and maintenance.
Let the beginners use cases that look like they’re going to turn into a giant robot. Obsidian Series 900D is built on a steel and cast aluminum frame, with solid steel panels and a fully painted interior. The brushed aluminum fascia resists scratches and fingerprints, and it’s just plain fun to put your hands on it.

The Obsidian Series 900D Super Tower PC case is the platform of choice for your next ultimate dream PC.

It’s not just big - Obsidian Series 900D has been carefully engineered for fast builds, easy upgrades and flexible expansion. The aluminum frame and solid steel panels give 900D the rigidity and strength you need for multiple teardowns and rebuilds, and the brushed aluminum fascia completes the look of understated overkill.

Legal DisclaimerLooking to save money on an amazing case and/or buy a cheaper than new watercooling case then you found it! The case is being shipped with some parts dismantled, which is the reason for the price being so low. It was used for watercooling so many drive bays, screws, or mounting plates have been disassembled. Pictures available upon request. I can re-assemble the case to it's retail design upon request, however the price will be increased for this. Only noticeable issues are two identical 1 inch scratch on the glass, the cuts are not deep and not really noticeable. If you have any questions or concerns please contact me directly prior to purchasing! This being a computer case, a large and pricey one, there are no returns.

Screens for dust collection also work well. The side facing internal drive bays are nice as it moves the intake fans to the front.
Only improvements would be a mid plate to separate the cable chamber below from the main interior <-- however, you can make your own very easily.)
1. No wheels on chasis, this thing is heavy and I would've like to see some wheels to make it easier to slide out from under my desk.
2. HD caddies are very cheap and flimsy, I feel that spending this kind of $ for a case they should not be cheap plastic
3. My right side lower door does not stay closed with the magnets, I have it taped closed unfortunately. Has been like that since day 1.
That said, the case definitely isn't lacking for anything. It has all of the space and mounts that you could possibly want, as well as some very clever ergonomic solutions. For instance, the expansion slots in the back cleverly use thumb screws, making them tool-less.
The case is made of brushed aluminum and is of the highest quality (with the exception of the cheap plastic HDD bays).
That said there is one major design flaw that I cannot overlook (the reason I removed a star). The lower hinged panels magnetically close. Unfortunately the doors come out of alignment very easily (the hinge may warp when opened), making the magnetic clasp completely ineffective. There is no other physical latch, meaning that once they are incorrectly aligned the doors will not close.
I can only assume that this problem is atypical. Unfortunately I already had my rig built by the time that this became a problem and it would be a colossal pain to disassemble everything, repack the case and send it into Corsair for a replacement.
1) The hard drive trays are kind of flimsy and don't work great with SSD's. They also don't latch very securely.
2) The fan cables for the front fans are not long enough to reach all of the ports on my motherboard. Ended up leaving one fan disconnected until I can get a fan controller. That said, I don't really need all of the fans for my particular setup so its not a huge deal.
These two complaints are minimal compared to the case overall and is not worth deducting a star from such an amazingly large case. My goal is to never have to buy another computer case again.
