So I pulled the trigger for this big boy. WOW. It is huge! Which is OK with me. Room to put the case is not an issue. Room inside of it ,will never be an issue either. One of my concerns was that this case is touted as a water-cooling case. Not much mention of Air Cooling. But I figured 3-120's in the front , 1-140mm in the back and up to 4-120's on top, I could create enough air flow. I mounted a Phanteks PH14 on my FX-8350 with room to spare. I am comparing the Air cooling to a Corsair 600T with cut-out grills (front-top and back) a Bitfenix 200 pro in front- Bitfenix Pro 230mm on the side and 3- corsair 120AF's on top, one in the back. (Very good airflow)... To the 900D with an additional 2-120 AF's added to the top in exhaust mode. Just to see if air cooling was as good as the 600T. Verdict: Almost exactly the same., within a degree or two on all components. My XFX-7950 DD benchmarks on Unigine Valley at 68 to 69C, My FX-8350 running AMD OD stress test at 50C (4.0ghz bouncing to 4.2 turbo..I had running apps at the same time) Northbridge 47C. SO...Air flow is as good as a modded 600T. The 900D is pretty basic for equipment, but giving you the option of almost anything. It has room for 15 fans. But, no controller. It would have added too much to the price I am sure. So I added a Lamptron FC2. 2 DVD Multi drives (Yes..I have DVD drives!)and an NZXT Card reader. I removed the top HDD cage and used the lower one. It is "Hot Swappable" for 3 drives. So from the window, no drives are visible. The quality of the 900D is unmatched. Solid. Very typical of all Corsair Cases. It was packed with a lot of care, protective strips on almost every edge, Plastic sheets on the window and front panels. Wrapped in a Plastic bag and lots of Styrofoam. Every door was taped. The box stands a little over waist high, and I am 6'1". It's a BIG box. The 900D may take a little getting use to if you have never owned a Super tower. Yes..it is big! But sooo pretty. It's beautiful. The word "Monolith" comes to mind. The 900D may well be the last case you will ever need. Highly recommended buy. And YES..for AIR COOLING too. Update 28 Oct: With 2 Phanteks 140's in the top, 1 in the back and removing the top 120mm in the front(Corsair) fan, replacing it with an internal mounted Phanteks 140mm it dropped my 8350 stress test temps to 55C at 4.7ghz WOW! As soon as Phanteks 120mm's come back on the market I will put 3 in the front and remove the 140. I also put 3 Corsair AF 120's in the bottom of the side panel and removed the outter shell on the door. It goes to show you that this is a great Air Cooling case as well. Review: Monster case with more room/space then you could ever hope to fill. - When I first saw my case by the front door, I thought they had delivered a dinosaur. Jokes aside the case is fantastic. I bought this case to replace my 800D. Transferring the ''guts'' from my old case to the new, was so much easier than I hoped. No unnecessary side-paneling would be in the way. I just opened both side panels and it took me about 45 min to move a MB, 1000W PSU, and my Kraken x60. The panel for organizing cables is awesome, they come with plenty of room and clips to store cables. I could easily reach the annoyingly placed USB 2.0 cables on my X79 sabertooth without removing the GFX card. Now I bought this case so that I could future-proof. I see room for 2 PSU's, 3 large radiators, and enough 140mm fan space to blast into space! My only caveat for this case are the small magnetic sidepanels on both sides. They can never stay closed! It's annoying when I listen to music loudly or I hit the computer when I'm getting up, and they open and don't stay closed. I also found it difficult to clean or install my radiator on the top without any instructions. I had to go on youtube and look it up, what's up with that?

Overall 4/5 ### ⭐⭐⭐⭐⭐ Massive But Awesome *by M***S on October 25, 2016* I love this case. Hands down the best case I have ever worked with. There are lots of features. Corsair went cheap on only a few small details but overall I think it is worth the money. One thing that could use an update is the front panel. There are two USB 2 ports headers (four ports) and only two USB 3 ports. No Type C on front panel. Would be useful and could use an update to have only USB 3 on the front. The bottom panels are a bit flimsy, I have one that is constantly bending because the metal is thin, I even loosened up the resistance on the hinges but the metal still manages to bend a bit, so I had to unscrew the hinge and bend the metal back, basically I can't really open it very many times as the construction is a bit cheap there. That aside, I still absolutely love this case. The space you have to work with is fantastic. This case is HUGE. I had a Thermaltake LCS Armor+ case before, which is considered a "Super Tower," and I will say this: if that case was a super tower, then this is a mega tower..it's massive. The case weights 50lbs EMPTY. It's huge, wouldn't fit under any of my desks so I have it sitting up top, which is fine because my build looks cool :-D This case is a beast..no kidding. Air flow is not an issue here, there are FOUR locations you can mount a 280mm radiator (that's four 120mm fans) Those same mounting spots can have fans mounted there. The nice thing is that the front bottom panel is removable so you can reveal the fans while still having a dirt screen/filter. That filter exists on the top, the bottom side panels and the bottom front panel - very very handy, will keep your case clean. One of the mounting brackets at the bottom is hidden underneath the hard-drive bays so there is a little disassembly required to retrieve the bracket to be used for fans/radiator. This is specifically for the LEFT bottom door. In order for me to fit my XSPC Photon 270 reservoir, I had to drill into the case. I didn't mind though, that's part of the fun. Really no negatives here, it would be nicer to have ALL cutouts to have grommets, but honestly this is the most I've seen so it's no big deal. I'd remove one star because of the front panel, but considering that this case came out a few years ago, it's understandable..just wish they had updated it. This case isn't for everyone, this is a very very very tall, wide and long case. It's for crazy super-builds. If you're looking for a nice mid-tower, I recommend the Corsair 750D. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/1216286-corsair-obsidian-900d-cabinet-tower-case](https://www.desertcart.pl/products/1216286-corsair-obsidian-900d-cabinet-tower-case) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-07*
