Obsidian 650D Gaming Windowed Midi Tower Case - Black (CC650DW)

The Obsidian Series 650D mid-tower case is manufactured with strong, stamped steel parts for increased rigidity, and coated in a black textured paint. The front panel features a beautiful black brushed aluminum faceplate to bring a subtle elegance to your next build.

A large, black 200mm intake fan hides behind the front dust filter, quietly pushing vast amounts of air over your hard drives and video cards. The air is then exhausted by a second 200mm fan on top of the case, and a rear 120mm fan. The top fan can be replaced by dual 120mm or 140mm fans, and is pre-spaced for a dual radiator if you’re interested in watercooling. And all fans are controlled by a three-mode, four-channel fan controller should you want to make your own choice between noise and performance.

Amazing case but fans are loud

This is an amazing case, good for water cooling. The only downside is that the fans that come with the case are very loud. The pull-down clips are very good for getting into the case quickly. One other problem, but I don't know if it's just me but my main side panel take a bit of jiggling to get in properly. Only a couple of downsides to an excellent case.


A special case

In the end i went for this, and i'm so glad I did, the things is a monster, but it looks sleek as hell, just awsome!

Was my first build and every time I had a cable I thought 'i know i'll go through the back'!! So good cable management, and so much space. I have a massive card and cooler and i think any smaller case might have had issues, but its just amazing and I cant stop looking and my z87 oc giga and gtx680 MSI flashing away though my windown.

Foir under 150 quids its great, im so happy i choose this case


good case

good quality case.
This is a lot quieter than my last case.
Just a couple of negative points.
One of the tool-free optical drive bay clips broke on trying to fit my first DVD drive.
clips binned and screws fitted.
Also the rubber pads from the front feet came off during the build process and have had to re stick them.
Apart from these couple of small negatives I am totally happy with this case and the service from Overclockers
and it is still worth 5 stars.



still lovin it

Iv had this case for a year now and i still have no complaints. its been bashed a couple of times yet the finish looks brand new. excellent choice for a water cooled gaming case

Fantastic Case and Incredible Customer S

I purchased this case less than a week ago, delivery as always was fast. The case itself is fantastic and of stunning quality.

After about 2 days the fan controller built into the case died, but corsairs customer service is incredible and a replacement fan controller is already on its way.

I will definitely be buying corsair products again if this is the level of customer service i can expect every time.

Im still going to give this 5 stars as it is an amazing case.

Lots of pros, some are:

Lots of space! Can fit anything
Good air flow
Well thought out design and placement within it
Nice solid feel and finish to it
Good cable management inisde the case
Brilliant side panel connector, makes working in it very quick and easy

Only three cons:

There are issues with the fan controller, that it overheats and literally melts so I wouldnt rely on it

Needs more space between the back of the motherboard and the outside case for cables as it makes the side bulgde out

The wire mess at front fan intake makes a slight wurrling noise when the front fan is set anything other than low - to be honest tho I have never needed it higher

Daz 2012-04-05

Great case!


looks great!
pleasure to build with.
side pannel clamps are awesome and saves alot of time.
all intake fans have dust filters.
room for ANY graphics card.
easy cable tidying
good cooling
Top panel HOTSWAP is usefull
nice brushed front panel
lots of front USB
really nice and strong tool less drive bays, and if needed can be attached with screws.
the hard drive bays themselfs can be removed (room for bigger grahics cards/watercooling)
can use 2 140/120mm fans in the roof


front dust filter hard to clean.
can ONLY use a 200mm fan in the front.
no internal USB 3.
fans loud above the lowest setting (never need to use high setting)
large USB devices will not fit in front panel.
could do with a little more room for cable tidying (more room between the back sidepanel and mobo tray)

Great Case

Very well thought out case and the fan sound issues aren't that bad the front one does hum but with the sound dampening fan mountings and lower powered fan cables supplied with this case they are nice n quiet in mine!

Loads of room for crossfire without cables getting in the way also.

Only real gripe is the cable management side of the case is tight so you really have to be methodical in arranging cables.

Overall very pleased with case.

A flawed classic ?

Awesome case in almost every way, build quality, looks, ease of build, features, cooling, etc.........but the fan controller is utter pants, all it does is make a horrible whining noise. It makes more noise than the actual fans...and they are not that quiet.
Replaced with an Akasa Trio controller and Apache fans and it is almost silent, only the graphics card can be heard on load.
But I am a perfectionist...I want silence or as close as possible I can come to it. This is a great case for the price, loads of room and the best cable management options (would be nice to design slightly more room between the back panel and the mobo. USB-3 solution not perfect, can Corsair not supply a header cable..? Still recommend it though as I don't think I can find a perfect case and this comes very, very close. But for the money it rocks. All these niggles can be worked around and kitted out this looks the business. Honest I like it a lot.

Corsair at it's best

This case has it all
Cable managment
A window!

Best case i have ever owned. Top service from OCUK

Carl Bennetts 2011-10-03

Brilliant Case, But...

The case is absolutely awesome. The cable management options are a-plenty and it looks stunning. I only have one criticism and that is the slight buzzing noise from the fans at low and medium speeds. At high fan speeds, the buzzing disappears and at low speed it is slightly noticeable. However, at medium speeds is where the buzzing is quite annoying.

For the first week or so, I just used the low and high speeds for regular use/gaming respectively. I recently bought a sycthe kaza master fan controller and with the controller the noise has completely disappeared.

Overall I am extremely happy with the case and the slight buzzing is not a big enough criticism to take away a star from the rating.

very good

if your in the market for a new case this has to be a no brainer i think . theres nothing i can say wrong about it.. nice clean looks excellent to work with' i was a tad concerned about noisy fans from other reviews i recieved no repair kit or anything and the fans are good not loud or buzzing so i think they must have sorted the problem , cant comment on the 120 exhaust fan as i removed it for the antec cpu water cooler all in all i think the cost is justified on this case because its very very good.
+ overclockers service second to none very quick hassle free

scooby keatsy 2011-07-24


this really feel like a pro case, easy to cable and look great, the 2 huge fans are fine for me not too noisy at all , well i cooled the cpu in water , that for my experience the most loud fan , for the rest this is my case from now on

paolo 2011-07-21


I was worried about getting this case as many people complained about the fans but i can say that i did receive the repair kit and it works fine. Keeps nice and quiet. The fan controller doesn't seem to be noticeable when you change fan speeds though so i attached it to the motherboard instead. Great looking case, glass side it really good. Can get marks easy on the front but comes out in a quick wipe.

For a midi-tower it's flipping enormous!

The first case since my beloved Akasa Eclipse perished that I have really been blown away by and I can now see why people rave about Corsair's cases. It really is a stonking piece of kit and an utter joy to work inside of!

That being said, for a midi tower it positively dwarfs my old Coolermaster Elite case - it's flipping cavernous inside!!

Service from OcUK was so brilliant, hardly bears mentioning seeing as this is the overwhelming norm for them ;)

Theophany 2011-05-26


ordered this friday and got it on saturday it is one hell of tower love this cases and i did get the repair kit with this

daniel 2011-05-08


Ordered this case on wed morning it arrived friday morning all the way in ireland, fantastic, speedy delivery by overclockersuk, the case is great bigger than i expected but so well made, the door latches are a nice feature. Not much more to say about apart from i recommend this to anyone who wants a well made case in an almost full tower size its worth every penny. thanks to overclockers uk i will be buying alot more from you guys in the future.

Sean 2011-04-08


I can only say, this case is amazing. I have the rattling problem with the 200mm fans but I just replaced them with three super silent Fractal Design 140mm, two as top exhaust and one as front intake... this case is basically a Corsair 800D in smaller so if you like the 800D but think that it's too big, then this case is for you.

VasVas 2011-04-02

great case

bought this a few days ago and was very impresed with it has a built in fan controller which can handle 4 fans and can accomidate gpu's with a lenght of over 300mm :) has removable hdd cages which are ssd compatible, if you remove cages wthe max gpu length is over 400mm, has a massive gap on the mainboard tray so you can change heatsinks without taking your board out.

last but not least temps are very good keeping 4.3ghz core i7 at 53 degrees under load and overclocked 6870 at 56 degres under load

buy it, it's a brilliant mid tower case with lots of great features
