Best case I've built in - perhaps ever
I've been building PCs for 25 years, my first one was an 80286-20 with a 20MB MFM HDD, so I've seen technology get better and better and usually everything gets simpler with time. Nowadays with overclocking there are needs around using watercoolers, extra fans - funny looking lights (to me, I'm old), etc. Amazingly, power supplies, outside of the connectors they now use, have remained relatively the same over the years. So have the screws. The wattage has increased for today's demands, but otherwise they are fancy transformers of AC into DC. Nothing exciting. Until I bought this case, the cases themselves fell into this same category: I saw no real substantial improvements from AT-designs to ATX, mini-ATX, etc. for 25 years. With this case, Corsair though now makes a PC builders' life much easier, the motherboard standoffs are already installed (thank you, Corsair) and the backplate only requires 2 or 3 cusswords to line up with the motherboard at the time of installation instead of 50. The airflow is better than most, and there's a lot of room to add more fans (and I recommend using corsair fans, they are the quietest for the CFM/airflow they provide) if you so desire. As other reviewers have mentioned, this is a big case (full size so it's easy to fish around wires when you have to). The most important aspect to me, as one reviewer put it, is that it didn't look like it just came out of a Transformers' movie - this is an elegant looking, grown-up case. It'd look equally as nice in an upscale office environment as it does at home. It's an easy case to build in. It's got airflow. It looks nice. I submit that having a caster kit available would be nice, but for many of us it's not terribly necessary.

One of the best PC cases I've ever used
I recently bought this case for a new PC I built for myself. I wanted something that had plenty of room for a liquid CPU cooler and fans and airflow, and this case delivers. Also, the size makes it easy to work on inside if you want to replace or upgrade something. Just know that this is a big case and might not fit well on all computer desks. Pros: - Looks nice and professional - It has plenty of room for things like a liquid CPU cooler and a long GPU - Organized: The different sets of screws were in separate bags. Also, the case allows good cable management, allowing you to route most of the cables and chords behind the motherboard so they don't clutter up the case above the motherboard too much. - Screwless installation for 3.5" and 5.25" drives makes installation of drives fairly easy - It includes real expansion slot brackets rather than pop-out throwaway placeholders that many other PC cases come with - It comes with 2 front fans (140mm) and a rear fan (most other caeses only come with 1 front fan, and some don't come with any front fans at all). The fans are quiet. Cons: - The front panel is supposed to latch in place, but it doesn't stay on very well. I contacted Corsair and they replaced my front panel for free. - Cosmetic: If you install an optical drive or card reader in one of the 5.25" bays, the front of the drive isn't flush with the front of the case - Know what you're getting into: It's a big case and might not fit well on some computer desks. Other thoughts: I installed a liquid CPU cooler to the top of the case using the long fan screws that came with the cooler. I put the fans on top of the radiator, with the long screws going through the top of the case, through the fans to the radiator.

Great case
This case is great for people looking for a full tower case that has room for expansion and cable management. The nearly 1 inch space behind the motherboard tray offers the perfect amount of area when dealing with cable management. I was able to fit an 24-pin plug, 2 6-pins, an 8-pin, a swiftech fan hub, all the included case wires, and 5 fans worth of wires in the back without causing any flex or bend in the side panel despite my shabby cable management. The the hard drive cages are removable in case you want to add a 240mm radiator onto the front panel (mine is mounted on the top). And the SSD mounts on the back have become my favorite method of mounting SSD. Just simple slide the SSD in and press the tab next to it to pop it out, it's wonderful. The fan filters arent extraordinarily fine but are capable of blocking most dust from entering your chassis. There are three total, one on the front and the top and another, thats more protective, on the bottom where you mount the Power Supply. The filter on the bottom rests in a tray that is easy to take out, the filter on the front is attached to the front panel and is taken off by pressing on two tabs on the top corners of the panel and finally, the filter up top is my favorite. It's a magnetic screen filter that can be taken off as easily as lifting some paper. I frigging love this thing. As well as being cool to mess with, it actually cleans well by just running it under some water and you're good to go! And last but not least is the overall look of the case... The brushed aluminum chassis along with the large windowed side panel makes for an absolutely gorgeous case...so long as you don't stick you're oily fingers on it as it will leave fingerprints on pretty much anywhere you touch. But still, sticking your rig into this case gives you're hardware the ability to show itself off in a stunning way! Huge thumbs up from customer.

Really great case and I've had it now for four years
I purchased this case back early in 2017 to make a new build with after having lost everything in the Erskine fire of 2016. I was definitely not prepared for doing this quickly and as such took my time to shop around a bit. What makes it harder is any time you buy things sight unseen. Online purchases are always a gamble as a result if you're not ordering staple items such as monthly purchases that you already know and trust. Well, I lucked out. The Corsair CC-9011078-WW Obsidian Series 750D Airflow Edition, Full Tower ATX Case gave me all the room I needed for the full size ASRock ATX motherboard and all the trimmings including the NVidia GTX 1080 video card and more. The design and durability to make it happen is in there. The design is exceptional for hiding cables away so it has a neat and functional appearnce. The "no tolls required" for many things such as hard drives and drive bays is nice. However, you'll likely need a screw driver for most everything else. It's a fairly sturdy case as well. I've seen heavier duty for sturdiness, but those cases will run you 4 times what this one does and you'll definitely need to consider all the things you intend to put in them before buying because they tend to be very proprietary for mounting components. I had one such case, loved it, but it was lost in the fire as well. Replacing it would have been a financial nightmare. The case comes with a very nice easily cleanable grill for removing dust from the air intake surfaces on both the top and the front. Another one is located on the bottom for the power supply air flow that simply slides out like a drawer to the rear of the case. One area of concern that I had early on was reviews that had some negative things to say about the plastic clips molded into the front cover that close the top of the front cover into place, but after 4 years they seem to be doing just fine. As a result of reading those reviews I've been rather gentle with those clips for fear of them braking off and I can certainly see where that would be an area of concern since it would destroy the functionality of the front cover were they to do so. However, four years later and they still operate just like new. Just push in to get the cover to release and push in again to have it lock into place. Just be sure to be careful to line up the bottom tabs properly first and don't used excessive force on the top edge. If it doesn't simply push in to lock properly then you may have misaligned the bottom tabs. If a four year experience with this case that's still looks great and is still going strong doesn't sell you then I can't think of anything else to say. PS. For those of you who are into chicken lights, this case has a very nice windowed left side panel for easily seeing inside as well as a glow from the back of the case fan if it's lighted that can be seen right through it from the front grill. That was one of only two lights I have inside, the back case fan is lighted and the Corsair logo on the liquid cooler for the CPU is lighted as well. I might also note that I'm very impressed with the Corsair liquid cooler. It came as an already enclosed/sealed unit, installed easily, and it has worked perfectly now for those same four years. No heat issues and no leaks. Simply blow out the radiator with air pressure when you do your spring cleaning. Wonderful job by Corsair.

plenty of space and airflow - some minor manageable gripes.
I really love this case. The end result is a very clean installation, with unobstructed airflow. Ambient case temps and hard drive temps are at a comfortable level. The stock fans are quiet. Cable management options are fantastic. Its better to plan ahead though. A few pointers from experience. 1. The 8 pin PSU power cable that attaches to the motherboard was too short to pass through the grommet and route behind the the case. I had to buy some PSU extension cables which turned out looking awesome in the end. If you are going with a PSU extension cable route, get the size 30. 2. SATA cables do not have to be 18 inches long. you could get away with it, but it might end up an unseen bundled mess behind the back panel. 3. if you plan on filling up the mechanical hard drive bays like I did (plex server) buy a modular PSU with flat ribbon like cables. Seasonic Focus series PSU works well, at least it did for me. 4. The front panel 'reset switch' power cable is too short to reach the pins on my board. The power button and LED cables barely reach. If you look at the front panel cable lengths, you'll see the reset switch cable is almost a half inch shorter than the other cables, at least on mine. its plex server though, so I don't plan on hitting a reset button any time soon. other than that, great case.

Great product, great customer service
My case arrived and the motherboard mounting screws were missing. Fortunately I was still able to mount the motherboard. I emailed Corsair’s customer support and they were very helpful and sent me the missing screws. As someone who works in customer service I can appreciate how easy they were to deal with. As far as the case itself I love it. It looks very sleek and is made out of fine quality material. It’s huge and pretty heavy but I can’t really deduct a point for that because I bought it knowing that, but just something to be aware of because it is not easy to move if that’s something you need to do frequently, I don’t so it doesn’t matter. Building in this case was a great experience. This was my first time building a PC so how large the case is made it very easy to work inside of. And there are plenty of routes for cables to be able to hide them and make it look nice. The one thing that is hard is getting the tool less HDD trays to fit with the HDD installed in them. I believe this is intentional to make sure they won’t move around when the HDD is running. Just something to note that you may need to push pretty hard but it will fit. As the name suggests the airflow is great. The 3 included fans plus the heat sink fan I purchased for the cpu are more than enough to keep temperatures manageable while gaming. And the fans are all nice and quiet. Once I put my headphones on, even with no audio, I can no longer hear the pc running. Plus the large size means I won’t have to worry as much if I decide to upgrade in the future that parts won’t fit. Great product, I love the sleek and simple look but that is subjective, and great customer service. I will be a Corsair customer in the future.

Photos of the 750D to answer your questions
I had some questions when I was buying this case but I was very pleased when it finally arrived. This is a great case that is packed with features! Here are the highlights: - 3 fans are INCLUDED and installed. That was my biggest question. - CD drives install in front without tools. - Up to six 3.5" hard drives install without tools into two modular housings. As you can see from my photos, they can be configured different ways or you can remove either or both of housings if you don't need them. - Up to four Solid State Drives can be installed in modular carriers on the back side. You can remove any of these you don't need. - There's a dust filter tray under the power supply that slides out for cleaning. - The top screen is held in place with small magnets. This PC will be located under a desk so I don't have to worry about anything spilling into the case from above. - The front panel opens by pressing the top corners of the panel. - NOT INCLUDED are the power supply and Blu-ray drive in my photos. But you knew that right? I like it when I can use the same brand power supply with the case and I've been very happy with Corsair power supplies in the past. The 750D is a huge case that could easily be set up for a 6 drive RAID 10 array or many other configurations. I'll be using it for 3D rendering with a pair of RTX 2070 cards, i9-9900KF, and 64GB RAM. I removed one of the drive carriers because I'll be using a 1TB M.2 SSD and a single 4TB hard drive. I have network storage for everything else. What about aesthetics? This box will be used mainly for production, and maybe some gaming after hours. Its not a flashy case. It does have a nice side window but I mainly like its functionality.

Great looking case!
This review is based purely on the look and feel of the case as I have not received all my parts for my new build yet so I can't speak to the quality of the case as far as installation, but I will update once I can. ANYWAY, my first impression of this case was based on the box it came in, which is huge. You may expect a rather large case when you order a full size ATX, but I still found myself thinking "wow, this thing is big", for reference, I'm 6'3 and the case comes up to my knees. That being said, the size of the case doesn't hurt it aesthetically. The case feels solid and very well built on the outside. If you are like me, and you have the bad habit of using your case as a shelf/side-table, you may want to note that the top of this case is mesh for airflow purposes so you may not want to sit anything on top. As for the inside of the case, the "Modular Drive Cage System" feels delicate. Corsair uses a "Tool-free" design and the clasps to slide the drive bays in and out feel like they could easily bend or break if you aren't careful. The case comes with screws of various shapes and sizes tucked into one of the drive bays, along with 4 small zip ties. Otherwise, there is tons of room in this thing! Just eyeballing it, I cant imagine having any space issues. The glass side panel speaks for itself. This is a very professional and "mature" looking case, but the side panel will still allow you to show off some LED's and your wire management skills. One issue I did notice however is that the side panel does not "lock-in" very well. Aside from the two screws on the back, there is very little holding the side panel in place. Once you remove the back screws, the side panel won't immediately fall off, but if you breathe on it too hard be prepared to catch it before it hits the floor. On the bottom of the case, there is what I THINK is a sliding removable dust filter for the PSU. It simply slides in and out, I assume for ease of cleaning purposes. I'll try to update this once I finish my build.

Buen producto, de buena calidad
Muy buen gabinete para alojar mi tarjeta madre y demás componentes. funciona a la perfección, creo mejorara si aumentan el calibre de la lámina del mismo, ya que es débil para alojar componentes tan importantes. Pueden mejorar mucho, si el sistema de acople de las tapas laterales mejora, por algún sistema mas profesional y robusto. Mas sin embargo los acabados son decentes y muy buenos, me agrada el sistema de montaje de la tapa del filtro frontal y superior para la ventilación. es decente y de buena calidad.

A Fantastic Non-Flashy Enthusiast Case of High Quality
This is a great case for builders who want a simple more plain and non-flashy type of computer case that is stylish but not over the top. It can work well as a typical gaming rig, or would look equally nice in a contemporary office setting as a business workstation. The build quality is quite high for a mostly steel case, but not as high as a Lian Li aluminum case per se. It has ample space for cooling, radiators, 6 hard disks, 4 SSD drives, great cable management setup, accommodates a wide variety of motherboards, and runs fairly quiet. Everything is assembled and disassembled with ease, and the case has a lot of airflow. One thing I like is the inclusion of 5.25" style drive bays for those who still have a use for CDs, DVDs, DVDRW etc. as many case designs have axed such features with an eye to the future. I'm quite happy with this case and may buy another one in spring/summer time for a new AMD Ryzen 9 3950X build I'll be doing. Highly recommended.

Was für ein Monster!
Ich wusste, dass ein Full Tower bedeutend größer als ein Midi-Tower ist..aber so groß hätte ich mir dieses Case nicht vorgestellt! - 4 gummierte (große!) Löcher für die Kabelführung, - 4 SSD Halter auf der Rückseite, - zwei ausbaubare Festplattenkäfige á drei Steckplätze, - Staubfilter unterm Netzteil, vorne und ein magnetisches Staubgitter oben drauf, - 3 Laufwerkplätze, - 3 140mm Standardlüfter von Corsair, - genug Platz, um 2x 140mm oder 3x 120mm Lüfter oben zu verbauen bzw. um dort Radiatoren einzubauen - uuuund jede jede Menge Platz um sich auszutoben. Die Vorderseite hat ein nettes gebürstetes Aluminiumfinish, und der Rest des Gehäuses ist in mattschwarz gehalten, was ein wenig anfällig gegenüber Fingerabdrücken ist. Aber ganz ehrlich, wann betatscht man sein Gehäuse außer beim Ein- und ggf. Umbau. Ansonsten wirklich schick zum anschauen, wenn man auf monströse Cases steht bzw. den Platz, den solche Full Tower bieten, benötigt. Innerhalb des Gehäuses kann man wie man lustig ist seine Kabel verbauen, so viel Platz und so viele Befestigungsmöglichkeiten für die geschickte Verlegung der Kabel ist einfach grandios und ich hatte beinahe schon Angst, dass meine Kabel zu kurz sein würden, zu meiner Überraschung ging das Verlegen ziemlich problemlos diesbezüglich. Allgemein war ich nach 3 Std Umbau (einfach alle Komponenten vom alten Gehäuse ins neue) fertig und das war mein erstes Mal, dass ich das als Ein-Frau-Mannschaft erledigt habe. Es war ein sehr angenehmes Gefühl alles einzubauen und hat auch Spaß gemacht, zu keiner Zeit musste ich mir Sorgen machen, dass die GraKa (ZOTAC GTX 970 AMP! EXTREME CORE EDITION) nicht passt oder ich Platz- und Lüftungsprobleme bei den Festplatten (habe zur Zeit 5 Stk. von WD) bekomme. Einziger Punkt, bei dem ich auf dem allerhöchsten Niveau meckern könnte wäre, dass man für die extra SSD Steckplätze ein gerades SATA Kabel benötigt, ohne angewinkelten Stecker, was ich zur Zeit nicht im Haus habe. Nach dem ersten Anschalten war das erste was ich bemerkt habe: Das ist aber kühl hier! Die verbauten Lüfter verrichten solide ihr Werk und blasen ordentlich Luft durch das Gehäuse, meine Grafikkarte hat auch 'nen kleinen Kälteschock erhalten und läuft nach dem Umbau in dieses Gehäuse um 5-10°C kühler, bei den anderen verbauten Komponenten verhält es sich ähnlich. Ich würde sagen, das Case macht seinem Namen alle Ehre! Wer wert drauf legt: die Lüfter sind nicht die leisesten, im Vergleich zu meinem alten Gehäuse NZXT Phantom (Midi-Tower, der der wie ein kleiner Stormtrooper aussieht) mit Standardlüftern, laufen die von Corsair ein wenig leiser (dafür haben die Corsair Lüfter keine LEDs verbaut, was natürlich kein K.O.-Kriterium ist). Insgesamt bin ich mit diesem kleinen Monsterchen von einem Full Tower mehr als zufrieden, finde den Preis auch komplett angemessen und würde es bedenkenlos wieder kaufen! (Updates und Fotos bezüglich dem Case werden bei weiteren Umbauarbeiten demnächst folgen.) Bei Fragen stehe ich gerne zur Verfügung.

Tout est bien pensé dedans pour qui veut manager ses câbles avec soin. Les ventillos fournis sont silencieux et efficaces. Rien ne dépasse les 30 degrés en idle et 40 en charge dans le boitier pourtant l'enveloppe thermique AMD est conséquente avec le 2700x et un RX vega 56. La face s'ouvre facilement et le nettoyage est simple. La grille aimantée au dessus c'est top pour ça. Les supports SSD sont bien (4) les supports 3.5" eux sont bien mais leur chassis mériterait plus de rigidité (ils se déforment facilement). Plus de problèmes une fois des disques dedans ça rigidifie bien l'ensemble si on en a plusieurs.

Ottimo case!
Adoro questo case in tutto e per tutto! Non mi sono affatto pentito dell'acquisto. La cosa che più mi interessava era lo spazio sul retro per far passare i cavi dell'alimentatore, e in questo Corsair non mi ha deluso! Sono riuscito a far stare comodamente i cavi di un alimentatore non modulare da 850W (precisamente un Corsair TX850 enthusiast edition). Spazioso, funzionale ed elegante! Sull'estetica ognuno può dire la sua, a me piace moltissimo. Forse la finestra è un po' troppo grande, onestamente non mi interessa "mettere in mostra" i miei HDD o il mio lettore CD che ahimè un po' si vedono, ma nulla di grave, anche perchè si crea un effetto opaco generale niente male. Tutto il resto ormai si sa, la modularità di questo case è eccezionale, spazio per numerose ventole e eventualmente radiatori di diverse dimensioni. Sulla silenziosità non ho molto da dire, nella media. L'unica piccola pecca (se così si può chiamare) è il filtro antipolvere anteriore, facendo appieno il suo dovere dopo pochi giorni la polvere inizia ad accumularsi e si crea un leggero "velo bianco" sulla griglia che non è bellissimo da vedere, ma se siete maniaci del pulito in pochi minuti torna come appena uscito dalla scatola. Come detto in precedenza i filtri antipolvere fanno a pieno il loro dovere; in più di un mese di utilizzo, l'interno del case è ancora immacolato. Sul servizio Amazon nulla da dire; ho ricevuto il tutto in anticipo, la scatola era particolarmente rovinata in un angolo, a dire il vero era proprio aperta ma, fortunatamente nessun danno per il case. Soddisfatto!
