Corsair Obsidian Series 1000D Super Tower

Although it came out in May 2018, it will soon be a couple of years old, for those of you that need room, here it is. As can be seen, the case is big enough for 2 computers and will easily fit 1. Specifically, 1 E-ATX and 1 ITX motherboards with power supply space designed to fit in the bottom of the case.

Before you do any work on the case please ensure that you have some computer tools and an anti static ground mat.

Who is this product for?

You would think that this product is for the experienced builder, but how else are you going to get experience? Surprisingly, this case is for anyone that wants room and needs to have 2 computers in one case. For instance, do you want to game and stream?  After all, easier said than done, this is the case.

Even if you presently have a single computer now, thinking of a possible upgrade and have some spare cash. By the same token, yeah I know, who doesn't?  Specifically, why not pick up the 1000D? In short, move pieces from your old computer and do an upgrade in pieces. In addition, take your time, research the parts that you need and read the reviews. A good place to start, in the meantime, are my website reviews.

Overview of Features

The 1000D is such a feature rich case, in detail, starting with the spaceous 2 systems in one. Plenty of storage space for both of the systems, also included is an integrated fan and RGB controller. Chiefly, an elegant looking exterior in black brushed aluminium with 4 smoked tempered glass panels.

In addition, the 2 side tempered magnetically mounted glass panels are removable, and swing outwards from the back. Then, open the door and access the dust filters in the top, front and bottom PSU slide out panels. The I/O panel is nice and furthermore, there’s enough USB ports here for two systems.

Accordingly, easy to configure, attached to the Mini-ITX system and the rest to the ATX system. To point out, let’s not forget the pair of USB Type-C ports. Furthermore, on the front I/O panel for the main ATX system are the power and reset buttons. Last, in the back you’ll find the power and reset buttons for the ITX system.

Another cool feature unique to the 1000D is the backlit power button and the USB ports. In the same fashion, they have RGB LED backlighting in that portion of the case. Moreover, other ports include the 3.5 mm jacks for headphone and microphone. As can be seen, the absolute coolest features of the 1000D are the fan trays.

To point out, mounted on sliding rails and slides out of the case for easy access, unlocked via a thumbscrew. Additionally, around the back of the case, you can access the cable management by opening a pair of barn doors.

Commander Pro

In this case, through the doors into the bottom section of the case is a preinstalled Commander Pro. To explain, the integrated Corsair Commander Pro is a fan and lighting controller (mounted on the motherboard tray). In effect, users can control up to 6 x PWM fans and 2 x RGB LED strips through iCUE software. The controller also has four temperature probes and contains the plugs for the front panel USB 3.0 ports.

Also in the bottom are 6 x 2.5” drive trays, 5 x 3.5” drive trays totaling 11. As well as, lots of space for your cable management.

How to use

As can be seen, the case is very spaceous, you may have trouble filling it up with parts. All things considered, using two different motherboard systems in one case can be challenging. As a result, to avoid this potential issue, the 1000D has many cooling options.

In detail, the front panel holds up to 8 x 120 mm fans, 3 x 140 mm fans on top and 2 x 120/140 mm fans on the back. As a result a total of 13 fans - none included. Corsair says there is room for up to 4 x 480 mm radiators simultaneously (requires the purchase of additional trays). Therefore, by default, it will hold 2 x 480 mm radiators in front, and a  420 mm radiator on top. 

Certainly, fan and radiator installation is easier because the chassis has radiator mounting trays which slide out from the case. To emphasize, Corsair says there is a wide variety of pump and reservoir mounting points making it very flexible inside.

Cougar Gemini X

The Cougar Gemini X is another dual system build case and labelled by Cougar as the greatest. Not as big as the 1000D, some would tend to argue, but for sure is an excellent case for any builder. The top chamber can fit an ATX System and additionally the other can fit a Mini ITX.

Accordingly, the case can be placed vertical or horizontal to suit your space distribution. Durable and robust a case that will last for years. My review to soon follow.

Thermaltake Core W200

In short, the Thermaltake Core W200 Series is a dual system case that offers unprecedented space for your hardware and liquid cooling. As a result your system is built from the ground up. For this reason Corsair named the TT Premium product line.  Which in detail, follows the core values of Excellent Quality, Unique Design, Diverse Combinations and Boundless Creativity. In fact, under this product line, the Core W Series – Core W200 and Core WP200 super tower chassis with the Core P200 pedestal chassis can be used in combinations for different outstanding looks.

Consequently, the W200 and P200 can be combined to make up the WP200. This case combination will last for many years and will outlast the electronics.  My review to soon follow.


All in all, the 1000D is a big case providing for up to 2 computers systems and plenty of storage. Furthermore, included is Commander Pro, an integrated fan and RGB controller. In fact, the case is future proof which means you can keep upgrading for many years.

Above all, this will be the last case you ever buy. Important to realize, the case also has a 2 year warranty. By and large, the tempered glass panels and brushed aluminium exterior give the case a great look.

As can be seen, the premium price is offset by the outstanding features. Lastly, for all of you builders, modders, customizers, and hobbyist, the 1000D is a case you should consider. To sum up, use your imagination and you can build the dream machine that you want.

Finally, I hope you found the Corsair Obsidian Series 1000D Review useful.

Above all, I appreciate your comments and thanks for reading.

I like the 1000D too, the extra large chassis makes it so much easier to build with. You know I may even do some watercooling with it, don’t know. Do you think I should wait for the 11th Gen Intel CPU Core i9-11900K? You have ended my four day long hunt! God Bless you man.
Have a nice day.

    Hello Bluray,
    The 1000D is such a huge case, you could easily put 2 systems in and will easily handle any watercooling you want to do. As for the Intel Core i9-11900K, I have heard through initial reports like all of the Intel CPU’s, is that it is a power hungry beast using many watts of power which means that you will need to cool it. Make sure that you have the right water cooling components to handle the heat. Also are you looking at the RTX 3090? You will need a big PSU for both the CPU and the GPU.

    On another note, an issue with the AMD Ryzen 5950x is that scalpers are commanding big dollars for the CPU way over the list price. Keep these in mind.
    Thanks for dropping by and really appreciate your comment.
