Corsair Obsidian 750D Full Tower Case Introduction

The Corsair Obsidian 750D case was recently released into the wild, unleashing its Full Tower goodness.  This case is a smaller sibling to the Obsidian 900D and also takes on a lot of design queue from its smaller brother yet, the 350D.  The first Obsidian case, the 800D was released late 2009, and has evolved to what you’re about to see today.

The 750D is actually design is very simplistic, and I quite like this approach, so long as the case in question is functional.  Sporting a beautiful brushed aluminum front and matte black steel inside and out, the 750D is sure to appeal to the masses!  Even the side window is squared off and not a design that is all over the place, giving this case a very clean look.

The interior of the 750D features a ton of room inside with room for motherboards as small Micro ATX and as large as XL-ATX or E-ATX.  There are bunch of wire pass-thru holes with rubber grommets inside, which will help make wire management nice and easy.  There are two 3.5” hard drive cages inside that can be repositioned several ways, or just removed altogether.  I know a lot of people are moving towards solid state technology, so this little perk will help clean up your case and help provide better airflow inside.  Corsair does have four SSD brackets that are mounted parallel with the motherboard tray, which are positioned behind where the HDD cages would be.

Want a case that has a lot of cooling potential?  Well, the 750D will be right up your alley.  There are three 140mm fans included with room for as many as eight (120 / 140mm mixture).  This also means that there is a bunch of room for water cooling!  A kit like Corsair’s H100i would go perfectly with this case.  Or if you want to get something huge, you can definitely mount a 360mm radiator on the top and not have to worry about modifying your case.

What about price point?  I must say, the Obsidian 750D is priced aggressively!  The retail price is $159.99 at Amazon and $159.99 at Newegg.  This is very aggressive in terms of a full tower chassis already, but I have seen this case go for as low as $129 after rebate, which is incredible.  Talk about a crazy good deal for a case with this much potential!  This just might be the case you were waiting for!  With this case, too, you will get a nice two year warranty if you have any issues with it.

Let’s move on and take a quick look at the retail packaging and then see what this beauty looks like on the outside.

Corsair Obsidian 750D Packaging & Unboxing

We all hope that manufacturers pack the contents of our purchase inside something very protective, to help ensure shippers don’t damage the goods during transit, when purchasing online.  Sometimes they’re packed quite well but still manage to get damaged in transit.  Let’s take a quick look at the packaging the Corsair Obsidian 750D has to offer.

Starting off with the front of the packaging, we notice that Corsair kept the packaging very simple and not flashy.  This is one step to keeping the cost down for the consumer.  On the front we see a drawing of the 750D, a statement about the case by Corsair, and a few of the features.

The sides show you identical information, but in different languages.  You’ll find even more technical specifications here.

The rear of the box gives you an exploded diagram drawing of the 750D and all of the information that you found on the front in other languages.

Cracking the top of the box, we find that Corsair put some nice thick Styrofoam blocks and a bag around the case.

Here’s another view with the case out of the box.

Pulling off the Styrofoam blocks and the bag, we’ll find some more protection of fragile parts.  The front brushed aluminum panels have a plastic film over them, as does the side window.

Also included inside the packaging is the installation guide and all the hardware you need to install your motherboard and components.

This wraps up the packaging and unboxing portion of this review, so let’s move on and see what the exterior has to offer.

Ripping off the protective plastic on the front and side window, we can now see the true beauty of this case.  The Obsidian 750D is a very simplistic and elegant design, while trying to make everything functional.

Starting off with the front of the case is where you find the gorgeous brushed aluminum panels.  At the very top is the front I/O panel.  The 5.25” bay fillers feature this look, and below that is a large panel that bumps out and reveals two 140mm intake fans.  There is plenty of room on the side of the brushed aluminum to pull in air.  It’s a nice and well thought out gap that doesn’t detract from the look of the case.

Corsair Obsidian 750D Front

Here is a shot of the 5.25" bay filler itself, so you understand how it is held into place.

Taking a closer look at the I/O panel, and moving left to right, the 750D has a headphone and microphone jack, reset button, power button, 2x USB 3.0 ports, and 2x USB 2.0 ports.  With the reset button, you’ll notice that it is very small, and it is actually flush with the panel.  This feels like a horrible design flaw should you need to hit it.  I end up having to try and get my finger positioned just right to hit it.

Corsair Obsidian 750D Front

The cover that hides two fans behind is it very easy to remove.  There are two points that depicted with 5 dots, just like a 5 on dice.  You can see these on the bottom of the above picture.

Gently press these and you can fully remove the cover.

Behind that cover is also an easily removed filter for your fans.  Just pull down on the top of it and it comes out.

Jumping over to the left side of the case is where we have a nice squared off window.  This Plexiglas window is plenty large enough to showcase your hardware inside, so make sure you button up the interior and not make it look like a disaster!  You can also notice on the left side the side panel has a nice grip point, making removal easy.

Corsair Obsidian 750D Left Side

If you’re looking closely enough at the above picture, you will notice that there is a thumb screw missing for removing the side panel (at the top).  I later found this screw inside the case, wedged in one of the SSD trays.

Moving to the rear of the case, there is room for nine expansion slots.  This means that Tri-SLI or Crossfire will be easy to accomplish inside this case.  There is room for external water cooling, though these are holes you have to poke out metal fillers.  With so many internal sealed kits on the market, plus room for a 360mm radiator, I don’t think you’ll find a need to use these.  There is a single 140mm exhaust fan visible here and the PSU is a traditional bottom mount.

The bottom filter slides out the rear, which is what I’m showing on the right side.

Corsair Obsidian 750D Rear

On the right side of the case is a whole lot of nothing.  It’s just a nice plain side.  I must say, the thickness of the steel is a little thinner than I’d like to see as the panels can flex a bit.

Corsair Obsidian 750D Right Side

Hopping up top there isn’t much to see here either, but this is your first view of the top mount cooling potential.  What’s nice up here is the fact that Corsair has this section filtered.  This is something you don’t find on every case.  What I like even more is this filter is magnetic.  It is a little tough to remove if you have bigger fingers, so a point to lift it up would have been nice.  The edges of the filter are pretty rough, too, but not enough to cut your fingers up.  The bottom half of the below picture is with the filter flipped up slightly.

Corsair Obsidian 750D Top

Here’s another view of the filter.

Corsair Obsidian 750D Top Filter

Dropping down to the bottom of the case is where a single filter is placed, which will filter the air for your PSU.  As you can see in the below picture, this filter pulls out from the rear. 

Corsair Obsidian 750D Bottom

To the right of the filter is where more fans or a radiator could potentially be mounted, inside of course.  By default, this is where the hard drive cages are located.  You can fully remove them by taking out four screws.  Part of me would have liked to see this filtered as well, but at the same token there isn’t any active cooling here from the factory.  It is notched where it could accept a filter like the top one, but again nothing was included.

That wraps up the exterior of the case.  Let’s move on and see what the interior has to offer.

Obsidian 750D Interior Impressions

Full tower cases generally provide the benefit of a ton of room to work with inside, as well as a lot of room for alternative cooling options.  As I found out with another marketed full tower chassis that I reviewed, you don’t always get a lot of room inside.  Let’s see what the Obsidian 750D has to offer inside!

Corsair Obsidian 750D Interior

Once I finally popped off the side panel, I got to see how much room we really have to work with inside.  Needless to say, there is loads of room in here.  On the lines of generosity, Corsair definitely made your life easier with the oversized hole on the motherboard tray, and the standoffs are integrated into the tray.  One of the standoff locations is also a guide pin.  These simple things are what I like to see and they do make life easier for everyone.  There are five wire pass-thru holes that have rubber grommets, and the grommets are a nice thick rubber.

Corsair did stamp the interior with standoff locations for ATX and Micro ATX boards.

The 3.5” HDD cages on the bottom right can be moved or removed, and quite easily, too.  If you want to move or remove the cages, there are two screws beneath them by default.  Take these out and slide the cage forward and they remove with ease.  The cage on the left is slid forward slightly in the next picture.  The plates that the drives are on by default can remove by removing four screws from the bottom.  This will allow you to install additional cooling.

Here are a few configuration options for these cages.  As with any of the images in this article, you can click it for a larger view.

The top rear is where a single 140mm exhaust fan is located, and up top is where a radiator up to 360mm can be mounted.  I'm really liking this because cases that support 360mm radiators aren't the easiest to find.  I had to modify my own personal full tower case to accept a radiator of this size.

Below that are the nine expansion slots, which all have thumb screws to make expansion card installation a snap.  You'll be able to do tri-SLI or Crossfire with ease inside this beast.

On the bottom rear is where the PSU is mounted.  I was disappointed to see that there are no rubber or foam strips here to prevent vibration.  I honestly half expected them considering the cost of this case.

Looking towards the front of the case are the two 140mm intake fans.

Corsair Obsidian 750D Interior Front

The 5.25” bays on the top front utilize a tool-free mechanism.  Simply pop one of the filler plates out, slide your ODD in and it’ll click in place.  If you want to remove the ODD, you will just push the button and slide out.

On the reverse side of the motherboard tray is where you’ll get your view of the 2.5” SSD trays.  One of these trays was actually hanging loose inside from the factory.  There are four in total here and they just snap in place.  Also back here are the front I/O connectors, which include your front audio, USB 2.0, USB 3.0, and the necessary cables for the power/reset buttons and activity lights.

I removed the bottom two SSD trays and this is what you see.

Back here you get roughly 15/16” of room to work with, which is going to be more than enough for hiding all of your wires.  If you need more than this, well, I really don’t know what to say.

This wraps up the exterior and interior impressions.  Next up we’ll take a look and see how installing a basic setup is.

Hardware Installation Inside The Obsidian 750D

I’ve always been a huge fan of large cases like Corsair’s 750D, so I’m happy to see all of the room inside.  I’m going to take a look and see how easy installing a common basic setup is with this case.  The hardware used is pretty basic, so I’m going to see if there are any flaws that a common user may run into when installing inside this case.  Take it like someone just wanted a case upgrade for future build out and wanted to drop their current hardware inside.

So this is what the clean slate looks like.  There appears to be a ton of room to work with here, so let’s drop our ATX motherboard inside.

Corsair Obsidian 750D Interior

I was a huge fan of the guide pin and the molded in standoffs for the motherboard.  This made installation a breeze.  I was even very happy to see the enormous amounts of space inside to make component installation and cable routing extremely easy.

Once I dropped my video card in, which measures approximately 275mm, which is right in the ballpark of current generation cards.  There was more than enough room to drop a much larger card in here, and even more if you were to ensure one of the HDD cages wasn’t in the way.

In the following picture, I was thinking about keeping the HDD cages in their default location, but in the end I ended up moving them.  I decided I’d rather keep the amount of power cables used to a minimum by keeping my single HDD close to the ODD.

Installing my ODD was a snap with the tool-less option that Corsair has in place here.  The only thing that looked odd is how the ODD sits against the face.  The filler helps keep everything even and flush, but once removed, you end up having a gap here.  It looks funny, but it isn’t hurting anyone.

Dropping in the PSU and routing my cables was very easy with the amount of room inside, plus the wire pass-thru holes that were strategically placed.

On the back side of the HDD, I ended up having to remove one of the SSD cages to make my connections possible.  The power and SATA cables both stuck out too far to keep this cage in place.  A 90 degree SATA cable would have only helped a bit, but then you have the power cable to contend with.  It’s a minor flaw in my eyes.

Putting the side panels back in place is pretty easy.  They have a tongue and groove point that is at the front of the case and the rear screws on with thumb screws.  One thing that I noticed that’s strange here is the top and bottom don’t latch at all, rather they sit freely.  That’s kind of a cheap way to do it.

Showcasing your hardware inside was definitely made nice with the large side window.

Firing up the system the fans are fairly quiet.  The power button is lit up with a white LED, though I couldn’t get it to capture in my pictures.

This wraps up the bulk of the Corsair Obsidian 750D review, so let’s get some final words in and conclude this review.

Corsair Obsidian 750D Final Thoughts and Conclusion

Taking design queues from its smaller and larger siblings, the 750D fills the gap and presents itself as a full tower chassis.  What I always liked about full tower cases is the amount of room that you receive with them.  The Obsidian 750D absolutely did not fail to deliver in this department and made working with it a very pleasant experience.

Corsair Obsidian 750D

On the outside of the case, Corsair opted to keep the 750D on a minimalistic design and did a great job with it.  I always love black cases, so it you’re looking for another color, you won’t find it here.  The side window that is featured on this case is nice and large and done right.  You better make sure that your install is clean, otherwise your friends will be able to easily see the disaster inside!

Inside the 750D we found large amounts of room to work with, lots of strategically placed wire pass-thru points, and a bit of customization.  The ability to move the hard drive bays around or out altogether is a great idea and I’m very fond of this feature.  The cooling potential inside this case is huge.  It’s not every day that you run into a case that supports 360mm radiators.  I know for the case that I bought years ago, I ended up having to modify my case to accept my 360mm radiator, and if this case were around then, I would have picked it up in a heartbeat!

The Obsidian 750D will set you back $159.99 shipped on Amazon currently, but I've seen it as low as $129.99 after rebate on Newegg, making this a very aggressive price point for a full tower chassis.  You get so much with this case and at a great price point.  Included is a cool two year warranty if you have any issues with this case.

There weren’t too many flaws with this case, which I’m happy about.  Starting on the outside, I would have liked to see a slightly better design with the filter up top.  The edges are not smooth at all and will at least scratch you.  It also would have been nicer to see this filter be a little easier to remove.  The 5.25” bays look great with nothing in them, but they look odd with a drive in place because the drive doesn’t sit flush with where the filler was.

Corsair Obsidian 750D Top Filter

On the inside of the case, the only problem that I had was with the location of the SSD brackets on the backside.  I think it was a good try by Corsair to integrate these here, but it feels like some thought is still needed here because they got in the way of my 3.5” HDD.  I would have to say that they’re almost perfect, though.  For the price that this case is, it also would have been nice to see a rubber lining where the PSU sits to prevent vibration.

All-in-all, this case gets a “thumbs up” from me and I wouldn’t hesitate to recommend it to someone.

Legit Bottom Line:  Corsair’s Obsidian 750D is not only a fantastic case to work with and looks great, but it also has an awesome price point for what you get.  The flaws observed are quite minor and can be easily overlooked.
