Corsair Obsidian 450D Mid-Tower Case

For years, Corsair was known mainly for their memory and flash drives.  As times have changed, Corsair has been developing other computer hardware such as keyboards, mice, headphones, cases and other products.  They have four award winning case lines, the Vengeance, Graphite, Carbide and Obsidian; Legit Reviews has taken a look at many of these and has always been impressed with the quality and features.  Corsair has released a new model in the Obsidian line, the 450D.  This mid-tower case looks to continue the Obsidian tradition of keeping the case design simple with a brushed aluminum front panel, while offering a wide range of cooling options.

The Obsidian line includes multiple cases ranging from the small mini-ITX 250D to the largest Super Tower 900D, the 450D is in the middle as a mid-tower.  It measures 19.5" x 8.3: x 19.6" (LxWxH) and weighs just 15.4lbs.  It features a large side panel window, tool-less installation, dual hidden 2.5" SSD trays, SuperSpeed USB 3.o and multiple cooling options.

The Corsair Obsidian 450D supports up to three 3.5" hard drives without adding an optional hard drive cage and two 5.25" devices.  Cooling options are plentiful whether you want to stick with air cooling or venture into liquid cooling.  Supporting up to eight 120mm fans (common intake locations are filtered) or liquid cooling radiators up to 360mm there are few limitations on how you can cool your system.

As a mid-tower case, the Obsidian 450D supports mini-ITX, micro-ATX and ATX motherboards.  In addition, it will support CPU coolers up to 165mm in height, graphics cards up to 400mm in length.  That is a lot of options for a mid-tower case priced at $119 and comes with a 2 year warranty.

 Let's take a quick look at the packaging for the Obsidian 450D and then take a look at what the case offers.

Obsidian 450D Packaging

Corsair Obsidian 450D Box Front

Like most manufacturers, Corsair is going for pretty plain packaging for their cases, not many are using full color, high gloss packaging any more; not that this really matters with most of these being sold in speciality stores or online.  The front of the box provides a nice 3/4 view of the case, and a short list of the features (in two languages).  At the bottom the model information is presented in large text.

Corsair Obsidian 450D Box Back

The back of the box provides a nice exploded view of the Obsidian 450D showing all the removable parts.  Half of this side is taken up by text in four languages, which is just a repeat of the information from the front of the box.  It's great that Corsair is using one package for six different languages.  In the bottom left corner, some damage to the box, looks like something slashed at the box, I don't believe it is deep enough to reach the case, however we will verify no damage to the case.

Corsair Obsidian 450D Box Sides

The sides of the box look really busy, however all that text is just the specifications of the case; it is listed six times in different languages.  The graphic of the case at the bottom provides the dimensions, 496.4x210x494 (HxWxD). On one side, in the upper right corner is a little sticker that shows the exact model, and that this case includes a side panel window.

Nothing unusual in the method that Corsair choose to package the Obsidian 450D for shipping.  Placed inside a plastic bag to keep moisture away, and large Styrofoam blocks on the sides to ensure no damage to the case during shipping.

Corsair Obsidian 450D Accessories

Corsair includes a very simple one-sheet informational page, this sheet is used to alert the user to the various accessories and where to obtain the full user manual (hint:  online).  Included in the little box of accessories is four cable ties, four long fan screws, ten motherboard screws, one standoff, four optical drive screws, twelve SSD??? screws, and twelve short fan screws.

The Obsidian 450D continues the tradition of previous Obsidian cases of keeping a very simple but elegant design.  Corsair has made a few changes to the overall design with the 450D, however it's not a major overall.

The front panel has a beautiful brushed aluminum finish, at the very top is the common front I/O panel.  Two 5.25" device bays are below the front I/O panel, followed by the large vented section for the front intake fans.

Corsair Obsidian 450D External Front

The front panel I/O is at the very top of the front panel.  A large power button is placed right below the lip of the outer frame, while the other options on the front I/O include headphone/microphone, reset button, and dual SuperSpeed USB 3.0 ports.  Below the front I/O is the two 5.25" device bays, each of the covers have a brushed aluminum layer placed on the standard plastic cover. 

Corsair Obsidian 450D External Front Top

The bezel for the 5.25" bays is removable from the inside of the case, it is held in place by four tabs (one in each of the corners) and is tight fitting.  With it removed the 5.25" device bays are accessible, it's great that Corsair does not include any temporary covers for the bays, they are ready to be used.  With the bezel removed we can see the bare connections for the front panel I/O.

Corsair Obsidian 450D External Front Top No Bezel

At the bottom of the Obsidian 450D's front panel is a large vented area for the front intake fans.  Like the 5.25" device bay covers, this part of the front bezel is made out of plastic, with a brushed aluminum surface.  Corsair has placed their name on the panel, which stands out against the black case.

Corsair Obsidian 450D External Front Bottom

Access to the front AF140L 140mm fans is extremely easy as the front filter is held on by two push clips, and a slide in type hinge at the bottom.  This method of removal is great as it makes it extremely easy to clean the front filter or change fans. 

Corsair Obsidian 450D External Front Bottom No Bezel

The side panel has a large window that utilizes clips on the inside to secure it to the metal panel, so there surface is flawless.  The window is crystal clear with no blemishes.  We will be able to see how clear it really is once the system is built.

Corsair Obsidian 450D External Left Side

On the back panel, we find standard items.  On the left (what would be the top) is the 120mm exhaust fan and the motherboard I/O key slot.  Next to the fan are three liquid cooling holes that are not pre-punched and protected by rubber protectors.  Next is a small air vent, and the seven expansion slots.  Finally, at the right (rather the bottom of the case) is the power supply location.

The right side panel is plain, nothing to be concerned about here.  Possible for a little mod on this side to show off the 2.5" drive mounts.

Corsair Obsidian 450D External Side Right

The top panel is mostly vented and has a small fabric filter in place as well.  The filter comes off very easily as it is held in place by a magnetic strip all the way around the edge.  Peel it off and you get access to the fan mounts.  With the filter off, you can install 3 120mm or 2 140mm exhaust fans, or install a large liquid cooling radiator.

Corsair Obsidian 450D External Top

The bottom of the case is covered by one large filter, to cover the optional bottom mounted fans and power supply intake.  While many fan filters are removed from the back, this filter is removed from either of the two sides since it is held in place by tiny magnets.  There is approximately one inche of space provided by the legs of the case to remove the filter and provide ample fresh airflow.

Removing the side panel we can check out the interior. Here we find that the color of interior matches the exterior.  The motherboard tray has four large cable management holes, each of them protected by a rubber grommet.  In addition, there is an extra large hole for easy access to the back of the motherboard CPU cooler.  For drives, we see two 5.25" bays, and three 3.5" trays; not many for a mid-tower.  Between the 5.25" and 3.5" drives is a large open area, that appears to have room for optional drive chassis, however they are not included; the other option is to move the 3.5" drive chassis up to being directly under the 5.25" chassis.  There are many cooling options on the Obsidian 450D, with seven locations to install fans, or four locations to install liquid cooling.

Starting with the 5.25" drive bays, we find two tool-less brackets for installing drives.

There are three 3.5" drive trays included in the Obsidian 450D, with a light squeeze at the ends release the clips holding them in place so they can slide out.   Under the drive chassis a 120mm or 140mm fan can be installed. 

Corsair Obsidian 450D Internal 3.5 Bays

If you have built a case using tool-less 3.5" drive trays in the past couple of years, you are probably familiar with this design.  Corsair has included holes to install a 2.5" drive in place of a 3.5" drive using screws.

Corsair Obsidian 450D Internal 3.5 Tray

The bottom isn't very exciting, the power supply will be placed here, which will rest on four rubber feet to reduce vibration.  Next to the power supply is a bottom 120mm or 140mm fan mount.  If desired, a 240mm long water cooling radiator can be installed here by moving the 3.5" drive chassis up.

Corsair Obsidian 450D Internal Bottom

After taking a look at the back of the case from the outside, we know what to expect internally.  The fan is a 120mm AF120L which connects to the motherboard using a standard 3-pin fan connector.  The 120mm fan can be removed and replaced by a 120mm liquid cooling radiator.  The seven expansion slot covers are held in place with thumbscrews, which is always nicer than plain screws.

Corsair Obsidian 450D Internal Back

The top of the case can support two 120mm or 140mm fans, or up to a 280mm long liquid cooling radiator.  The top panel has a filter on it, which is nice to keep things from falling into the case through the large holes in the top.

Corsair Obsidian 450D Internal Top

On the back side the motherboard tray, we find nothing out of place.  There are four cable tie locations, one for each of the cable management holes.

The two hidden 2.5" drive trays are hidden below the large CPU cooler support bracket hole.  These are tool-less, simply slide a drive in and it is secured by a clip.

Obsidian 450D Hardware Installation

Being a mid-tower case, space is limited, however Corsair has doing a great job at making the interior of the 450D extremely roomy.  The spacious interior will help any user install their components rather easily.  While we mainly see four cable management holes, there is actually a fifth right by the 140mm exhaust fan for the motherboard auxiliary power cable.

The 3.5" hard drive trays is a standard design, the drive connections face the back side of the case, which requires the back panel to be removed to properly install them.  Putting a drive onto the tray is easy, slide the hard drive onto two of the pins and bend the tray slightly to align the other two pins.

Two 2.5" hard drives can be hidden on the backside of the motherboard tray, like the 3.5" drives these are tool-less.  These install even easier, pull the lever to make it easy to slide the drive into place and the lever holds the drive in place.

Corsair has preinstalled the motherboard standoffs, and made the middle standoff (right below the CPU location) a guide pin.  This makes it extremely easy to install a motherboard.  After a standard ATX motherboard is installed, we can see how much extra room there is to install the various components.  While installing the hard drives, I decided to move the 3.5" drive chassis to being right below the 5.25" drive bays.  Two screws hold it in place at the bottom, and only one screw at the top, of course it has metal rails for the drive chassis to slide into place.

The Obsidian 450D supports video cards up to 400mm in length, the XFX R7950 video card that was installed is 236mm, so there is a large amount of space available for the largest of video cards. 

On the back side, once cables started to be run I originally opted to use straight SATA cables, which will work, however they do stick out a little, using right angle connectors will fix this.  Cable routing otherwise is very simple and easy to keep organized.  While only a few cable tie locations are provided they are strategically placed to secure the cables with ease.

While the CPU cooler hadn't been installed yet, there is plenty of room in the cutout to install a CPU cooler at anytime.

Putting the side panels back in place is easily done.  With everything installed, we can step back and take a look at the side window.  The window is very large and clear, it allows the hardware to be shown off.

With the system turned on, the three included fans are very quiet and should keep the Obsidian 450D cool.  However, if liquid cooling is more your style, there are many options within the 450D to liquid cool your system

Final Thoughts and Conclusions

Available starting in April 2014, the Obsidian 450D follows the design tradition of the Obsidian line, keeping things simple, stylish and highly versitile.  The front bezel has a layer of brush aluminum which makes it look expensive.  The cooling options on the 450D include up to eight 120mm fans or liquid cooling radiators in four different locations up to 360mm.  For storage, it has two 5.25" device bays, three 3.5" hard drive trays, and two 2.5" drive trays.  If that is not enough, there is an optional hard drive chassis available to provide up to three more 3.5" hard drive trays.

The front panel includes a large mesh area at the bottom to provide a large amount of airflow into the two AF140L fans included with the 450D, which could be swapped out for two 120mm fans or a 280mm liquid cooling radiator.  At the top the Obsidian 450D includes two SuperSpeed USB 3.0 ports, and two USB 2.0.  I would prefer to have four SuperSpeed USB 3.0 ports; that might increase the cost of the case a little.  The power button is a little awkward being placed at the very top of the front panel right under the lip, its easy to see since it is flanked by two LEDs.

Corsair isn't wasting space in the Obsidian 450D, with the rise of popularity of SSD's, Corsair has placed two tool-less trays on the back of the motherboard tray so users can tuck their precious SSD's out of the way.  As is common there is a large hole in the motherboard tray that will provide more than enough space to install an aftermarket CPU cooler support bracket at anytime.  As for cable routing, there are only a few places to secure the cables, and with around 1 inch of space, cable routing could be a small issue, especially with the SATA cables, using right angle connectors will resolve this.

Priced at $119, the Obsidian 450D has many features that enthusiasts are looking for.  Multiple cooling options, large video card support, and a flexible interior for customization.  For some, the $119 might be a little high, however for a case with these features, a 2 year warranty and a top notch build quality, it will be hard to beat.

LR Recommended Award

Legit Bottom Line:  Corsair's attention to detail is obvious on the Obsidian 450D, it gives the feel of an expensive case without the high price.  It includes pretty much every feature an enthusiast wants without compromising the minimalist approach.
