CORSAIR OBSIDIAN 900D Cabinet-Tower Case

I was waiting for the 750D to come out, but I wanted a case that would last a long time with room for expansion, and I didn't really care for the thumb screws on the 750D doors. 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.

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

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.

Cierto es que la caja vale lo suyo, pero lo considero una gran inversión, hay tanto espacio, que voy a demorar un tiempo la compra de mi refrigeración líquida, los materiales de gran calidad, no se oye nada poniendo los ventiladores, aunque eso es gracias en parte a los ventiladores. La ventana es enorme e invita a hacer un montaje limpio dándote todo lo que necesitas para lograrlo. Me encanta, estoy enamorado de ella xD. Lo único malo que se podría decir de ella... es que es gigantesca y cuesta encontrarle hueco, aunque es tan fácil como tomar medidas y solo comprarla en caso de que puedas encontrarle hueco. Un saludo y si tenéis dudas.... compradla!.

Soooo, das ist mein erstes Gehäuse von Corsair, habs mir geholt weil es groß genug ist eine Interne Wakü einzubauen! Das Gehäuse ist extrem schwer (auch leer) ca 18KG, baut man dann noch seine Komponenten ein (dann hat man ganz schnell 30KG und mehr) wird es schwierig das Ding alleine anzuheben, nicht wegen dem Gewicht, nein aber weil es so sperrig ist. + gute Verarbeitung + Sehr funktional + man kann wirklich sehr viele Lüfter verbauen + auch viel Radiatoren 2x4er 1x3er 1x1er + abnehmbare Staubfilter + Design ist super + Grosses Sichtfenster + Sehr viel Platz hinterm Mainboard für Kabel und Stecker + Man kann alles vom Innenleben ausbauen und nach seinen Wünschen gestallten. + Innenraum ist riesig (aufpassen.... bitte die Höhe nicht außer acht lassen, falls ihr ihn unter den Schreibtisch stellen wollt) So nun zum Negativen: - Der Innenraum besteht hauptsächlich aus Plastik, (Schubfächer für HDD's etc.) machts das nächste mal 20-30 Euro teuerer und nehmt Metal, obs nun 18 KG oder 20 sind spielt bei dem Gewicht nun keine rolle mehr. - Die Lüfter die dabei sind sehr Laut. - kein Handbuch.... na ja einmal hätt ich schon eins gebraucht und zwar beim Deckel oben, der muss zur Seite geschoben werden nicht nach oben^^ Technische Daten Corsair Obsidian 900D Abmessungen 252 (B) x 692 (H) x 649 mm (T) Gewicht 18,6 kg Mainboard-Formfaktoren HPTX, E-ATX, ATX, Micro-ATX, Mini-ITX Material Stahl, Kunststofffront mit Aluminiumplatte Kabelraum hinter dem Mainboard-Tray 30 mm Max. Bauhöhe CPU-Kühler 210 mm max. Erweiterungskartenlänge 410 mm (520 mm ohne Festplattenkäfig) Slots für Erweiterungskarten 10 Frontanschlüsse 2x USB 3.0 4x USB 2.0 Front Audio (In/Out) Lüfter 3x 120 mm (Front, 3x 120 mm vorinstalliert) 1x 140 mm (Rückseite, vorinstalliert) 4x 120/140 mm (Deckel, optional) 6x 120 mm (Untergeschoss, optional) 1x 120 mm (Festplattenkäfig, optional) Laufwerke 4x 5,25 Zoll (extern) 9x 2,5/3,5 Zoll (intern) Besonderheiten Platz für vollausgewachsene Wasserkühlungen Hot-Swap-System für drei Festplatten (die hätten sie welche aus Metal nehmen können) Platz für zwei ATX-Netzteile Seitenteile werkzeuglos entfernbar Ich finde es ist ein sehr gelungenes Gehäuse, auch mein bestes und auch teuerstes bisher, aber obs den Preis von über 300 Euro rechtfertigt! Das muss jeder für sich entscheiden. Auch ich kann kein Klappriges Geräusch am Gehause feststellen. Sollte mir noch was einfallen werd ich dazuschreiben. Ich vergebe dennoch 5 Sterne weil es meine Erwartungen übertroffen hat.

Where do I start to describe this case? It's big, very big, it's so big that the only way that I can fit it on my desk is to have it running parallel to the wall with the windowed side panel towards me. It's the only case that I've ever used where I had to rotate it by 90 degrees just to reach the top screws when I was mounting the motherboard. My wife asked me when I was going to finish building it, when I said that I had finished, she asked me where was all the "stuff" that i normally had in it. It was in it. It's also beautifully designed (with one exception) with acres of space to route cables and make it a tidy job with the minimum disruption to airflow from cables. The area in the bottom can be used for Power supplies, yes, you can mount 2 of them, hard drive cages, fans and radiators, not all at once though. Oh yes, the one exception that I mentioned earlier. A big slap on the wrist to whoever decided that it would be sensible/funny to design? it so that the thumbscrews to mount the PCie cards could only be reached from inside the case and therefore had to be screwed/unscrewed by hand. I was tempted to knock a star off for that, but I decided that would be churlish, considering how good the rest of it is. Yes it's big, yes it's expensive and yes it's very good. If you want a BIG case and have the room for it I doubt that you will do much better.

das gehäuse ist noch immer eins der besten die es gibt, allerdings ist die beschreibung extrem mager (4 seiten wo nur auf 2 seiten paar details zum gehäuse aufgelistet sind)... man muss für die ganzen funktionen bei youtube schauen, allein wegen der versteckten schalter an der rückseite, oder wie man die abdeckungen abmachen kann... das finde ich ziemlich enttäuschend... außerdem wenn man grafikkarten einbauen will oder andere karten... das gehäuse steht im weg -.- man kann nicht wie bei jedem anderen einfach die schrauben der kartenbefestigung anziehen da sich diese leicht hinter der gehäuseabdeckung befinden -.- man muss mit der hand schrauben xD sowas hatte ich bisher noch bei keinem gehäuse, allerdings tausche ich die komponenten nur bei reparatur aus, darum verschmerzbar

This case is wicked but I didn't expect to have to spend an extra 25$ for a fan HUB with how expensive the case is.Keep in mind that YOU WILL NEED a fan hub if you even want the intake fans that comes with this case to power on.Regardless,this monster is overkill for a normal build even one with an AIO but perfect for a magnificent custom water loop.You won't ever complain about a lack of ventilation seeing as this baby can support 480mm of fans on EACH SIDE,360mm in the front and another 480mm at the top.To anyone wanting to have to spend ONCE and never have to worry again about potential future hardware upgrade.This case is totally for you. Cons: #1 - No fan hub. #2 - Screwing your gpu(s) is a totally pain. Pros: #1 - EVERYTHING ELSE.
