From the Manufacturer
A revolutionary combination of noise reduction and cooling.
Obsidian Series 550D is carefully engineered for noise reduction and sound isolation. But, it’s not just about keeping things quiet — there’s amazing cooling potential, lots of expansion flexibility, and the durability that Obsidian Series is renowned for.
Superior airflow for high-performance PCs.
Obsidian Series 550D comes with two front-mounted 120mm intake fans and one 120mm exhaust fan – more than enough for delivering the airflow required for a high-performance system. But if you’re pushing past high performance and into the realm of extreme-performance overclocking, there’s room for a lot more. The top panel provides room for two 120mm or 140mm fans, or a 240mm radiator for compatibility with Corsair Hydro Series CPU coolers and other liquid cooling systems. The side panel has mounting points for another two 120mm or 140mm fans for cooling multiple GPUs. In total, the 550D offers ten 120mm fan mounting points, six of which can also accommodate 140mm fans.
The silent treatment.
With many high-end PC cases, cooling is often provided without consideration for noise. Not so with the 550D: the front and side panels are fully lined with sound-damping material, and the top and side panels have their own sound-insulated vent covers to reduce noise leakage from unused fan mounting locations. The front air intakes are angled away from the front of the case for noise reduction, and the fans and drive bays use silicone mounts to reduce vibration noise. The result is a platform for building high-performance PCs you can live with.
Smart features for serious builders.
The extra touches like magnetically mounted dust filters and one-button side panel removal make building fun, and using a 550D-based system a rewarding experience. Expansion is easy, with eight expansion slots, six tool-free hard drive bays with removable caddies and integrated 2.5” SSD support, and four tool-free optical drive bays. The top drive cage can be removed to accommodate GPUs of up to 452mm in length. The diamond-cut brushed aluminum front panel houses two high-speed USB 3.0 connectors and audio ports.
The Obsidian Series: Designed by builders, for builders
World-class Obsidian Series cases are made from stamped steel and brushed aluminum, providing both outstanding durability and great looks. State-of-the-art features are engineered with the singular purpose of meeting the needs of professional builders, high-end system integrators, and performance enthusiasts. Builds are straightforward and efficient, and there’s room for nearly any system configuration you can imagine.

The case is not inaudible with components installed, even with the fans disconnected and a very quiet PSU like the Nexus Gold 1.1K. But it reads about 10 db softer than my old CoolerMaster. And it's not so much that you don't hear anything from the case itself; you just hear much less. What you may notice is not how soft the noise from the case is, but how much more of other soft sounds in the room you hear that your old system masked, which is actually a much better test than just a decibel meter.
With fans hooked up and using Noctua inline resistor motherboard connectors to slow the fan rpms, it is a very quiet machine, and still puts out reasonably cool air from the rear fan (even running five hi rpm 3.5 drives and an 8 core AMD CPU with a Noctua fan. The Graphics card is fanless). But it isn't like you won't hear it if it's sitting on your desk, as some commentators have said, unless perhaps you have a fanless PSU, only SSD drives, and totally passive CPU cooling. You will know it's there, as you would nearly anything with mechanical movements at that distance.
But there's a great YouTube video that shows audibly what happens when you take off one of the side covers. The noise jumps up immediately, and drops right back down when the panel is replaced. I've tried it with mine and yes the sound dampening effect is quite obvious. The sound insulation works.
Cable management is very good if not perfect. Fat PSU cables will tend to push out the back side panel if you run them that way, because the motherboard bay is deepened with respect to the drive bays. Great for tall CPU coolers; a little awkward for fat PSU cables, but nothing really unmanageable.
I thought the front door would be superfluous but I'm finding I actually like it closed, even though I have to open it to get to my DVD burner and card reader. The dual hinges mean you don't have to worry about which side of your desk or table you put it on. And it is a very classy looking piece of hardware, far more adult than the Christmas tree light gamer units. The fan filters also are a very welcome addition, as anyone knows who's looked inside an old computer chassis.
After many years modding my own units and usually having side covers off because it never made any difference in the noise level and made working on the system much easier, I'm finding it quite an experience to have a case where the sides pop off with the push of a button and you can actually audibly tell whether they're on or not. It's not really a totally tool-less unit. While the drive bays and the expansion slot covers and the hard drive bay nests mount with thumb screws, you'll need a screw driver to loosen when you first use them, and you may want to tighten them with one when you screw them down too. But all in all a great case. The best I've run across and at a fair price as well.
UPDATE: Well, after living with this case about three weeks I realized the CPU temps were running very high, even auto-shutting off under very high load (processing large video files in Adobe Premiere). It's an 8 core AMD CPU and they have tendency to do that. The Noctua NH-U9S I'd been using just wasn't adequate, even with dual fans. So I switched to a Corsair Hydro Series H90. CPU temps dropped by about 20 degrees, to the mid 60s under high load and low 40s most of the time, and mid thirties at idle. So clearly, if you have a hot running CPU, you'll need water cooling in this case, no question. It still all works for me.
The 550D is a moderately large mid-size case, about an inch shorter in height than the 650D which would be welcome for increased accessbility to the superior aspects of the MB, especially if you mount fans or radiators there, but clearance is accessible. Because space is a bit cramped superiorly, especially with a large heat sink installed, I would recommend attaching an 8 pin extension onto the auxiliary power header of the motherboard before you secure it to the case, and then pass it out the hole provided into the back section, making your connection there with the cord from the PSU. This will make it easier also to disconnect it if you need to remove the motherboard, or change your PSU. The standoffs for standard ATX motherboards are factory installed, but there are others included in the accompanying packets.
Conveniences missing from the 650D are the hotswappable SATA controlled HD bay, and the three speed system fan controller switch integrated into the top of its case. These are the tradeoffs for electing the model with the acoustic benefits which are solidly real, if that be important to you; however if not, consider the 650 for those extra features. The 550D's front USB3 connector is a standard USB 3 motherboard header, while the 650D, an earlier iteration, has two type A USB3 connectors, which have to be connected to the back I/O panel, since it was made before the appearance of on-board USB 3 headers on motherboards. It may be that Corsair has updated this, as I know Coolermaster has in some of their cases.
The push release side panels are a delight for ease of removal and reattachment, but, at least on my case, one of the panels is quite a tight fit(nothing bent) fit, more so than the opposite side which releases easily. It has loosened up a little with usage, and is OK. I suspect Corsair wants to err on that side to ensure no vibration.
Cable management is excellent. In this back compartment, there is not much clearance behind the motherboard, but it is adequate to accommodate the accessory power cord which has to be passed upwards to the superior aspect of the MB. There is a slight recess where most of the cables pass in from the PSU and then out again to plug into the various components and motherboard conections. The 6 lightweight trays for the HD's, also well recessed for easy connectibility, are a bit flimsy, but they do the job, and have silicone grommets to reduce vibration from mechanical hard drives which are retained without the need for screws which are necessary for mounting SSD for which appropriate holes in the caddys' bases are provided. Virtually all the intercompartmental passthroughs are grommeted, and are strategically located for a neat, and convenient appearance, as well asto maintain optimal airflow, free of clutter.
Magnetically-retained dust filters cover all gratings, including those that are covered with acoustic paneling, are a nice feature and easily removable for cleaning. The exception, format-wise, is the bottom filter which is a convenient pull-out type.
The case's panels are real dust, dirt and fingerprint catchers, but easily wiped clean with a damp cloth, if aesthetics, in that regard, be important to you. The door-style front panel, extending top to bottom, when closed, covers the optical drives, but has a cutout for the panel which includes the USB3 and power/reset buttons. The excursion of the door, which very conveniently can be set to open outwardly either to the right or left, is not hampered by attached USB cable connections or a flash drive, providing that the latter is of the standard relatively narrow format which fits within the height of the cutout on the door. This makes for a very clean look, but the releases of the door are a bit tight(best done with two hands top and bottom) and therefore slightly inconvenient, particularly if you need frequent access to your optical drives. As a workaround, you can leave the door slightly ajar, or even remove it completely, permanently, if you wish, and the case still appears "finished", but there will be a little more front fan noise, as a tradeoff, which is not a big deal.
If you decide you miss the fan controler option of the 650, there are plenty of aftermarket units you can buy which will mount into one of the 5.25 bays. You will plug your system fans into the connectors on that controller and run a power supply cable to the unit. Frankly, I do not think that is necessary, but, please keep in mind that most system fans have three pins, as is the case with most motherboard system fan headers, and are therefore not capable of power width modulation(PWM) control by the motherboard as the four pin CPU fan header is. Some of the newer, high-end motherboards do now offer 4 pin sys-fan headers, if that kind of automated control is important to you.
The width of the case(slightly less than the 650) is adequate to house the height of the large air-cooled heat sinks of Coolermaster and Noctua.
This case with all components is quite heavy. It has rubber feet designed to prevent vibration when interfacing with solid surfaces, but it makes the case quite difficult to move around for servicing, especially if it is installed on the floor within a kneewell, or on a carpet, for example. A very convenient workaround is to place the computer on a ¼ inch panel of plywood, where the weight works for you since the coefficient of friction between the rubberized feet and the plywood is substantially higher than that between the panel and the floor or carpet. This makes shifting the position of the computer a breeze while, at the same time, it will stay put on its panel. You can cut the panel to size and finish the surface, if desired, to blend into the decor. Also, if the computer is resting on a carpet, the panel mounting allows for better clearance at the base for ventilation through the bottom grate, as well as for cleaning its dust filter.
Incidentally, Newegg has made excellent Youtube video walkthroughs of the features and component installation process involved with both the 550 and 650 cases which you may wish to check out as potentially helpful.
BOTTOM LINE: Highly recommended option for a computer build with a well thought-out, versatile, flexible design with quality fit and finish, a conservative, elegant appearance, and nearly silent acoustic footprint. It may not be the best choice for ultragamers with severely overclocked SLI systems that tend to generate excessive amounts of heat; however, there is plenty of headroom, in that regard, for the vast majority of users.
Update 9/24/2012: I decided to take advantage of Amazon's 30 day return window, to request a replacement for this case because the "sticky" left side panel was not seen on any of the demo videos and I thought was a defect. Amazon promptly sent me a replacement. The first thing I did was to try the panel release and it was exactly the same!!! If anything a little tighter on the right side, and no difference on the left. I really couldn't understand why you'd have to actively pull on the panels after release, when they virtually popped free on the videos. I did what I ordinarily would have done right away on the original shipment, except that I didn't want to do anything that might alter the appearance if I wanted to return it. I just sprayed some silicon lubricant liberally on the latch release pins and bar, and lo and behold, the situation was markedly improved, if not virtually corrected. Also, if you find the front door release a little tight for your taste, spray the metal catches on the door, but NOT on the pins on the case side where spillover of the solvent may corrupt the adjacent plastic!! In my situation, where you needed previously to use two hands to release the door, it now moves easily just pulling gently on the top with the fingers of one hand. I'm glad I didn't remove my original component installation, and just sent the factory new replacement back to Amazon, totally unused.
I'm quite surprised no mention has been made of this in any reviews, so unless I received two "sticky" cases, please be advised how to easily correct this problem if you encounter same on your case. This minor design flaw certainly doesn't merit a star's deduction, as I am delighted with this case which is beautifully designed.
