CORSAIR OBSIDIAN SERIES 750D AIRFLOW EDITION FULL-TOWER ATX CASE

The Corsair Obsidian Series 750D Airflow Edition is a full-tower ATX case with a clean, elegant exterior and painstakingly-designed interior. The modular drive-cage design gives you more possibilities to configure your PC. You can have your desired cooling solution and components installed—fast and easy.

MINIMALIST STYLE, MAXIMUM POTENTIAL

The 750D Airflow has a clean, elegant exterior that dispenses arbitrary plastic add-ons in exchange for beautifully-brushed aluminum and solid steel. This rigid, rugged exterior surrounds a frame that has ample room for high-performance components and the sophisticated cooling you’ll need if you’re going to push those components to their limits.

HIGH-AIRFLOW FRONT-MESH DESIGN

The front panel is what makes the 750D Airflow different than the original 750D. Dual 140mm front-intake fans and a low-resistance mesh panel provide quiet, efficient air cooling performance for GPUs and DRAM.

MODULAR DRIVE-CAGE SYSTEM

The tool-free drive bays can be moved and removed, so you can use only what you need for your particular storage requirements. In turn, you’ll get increased space for components and better airflow potential.

FAST AND STRAIGHTFORWARD BUILDS

Smart design features and an optimized interior make this a true builder’s PC case. That’s because we believe building a system should be straightforward, trouble-free and most importantly, fun.

So much room and a sleek non-ufo looking design! 1/21/2020 6:31:40 AM

Pros: Tons of room to work around inside and manage cables.

Room for more hard drives and ssd's than you can afford.

Doesn't look like a UFO, sleek simple design.

Great airflow.

Cons: It's big (not really a con but folks on here don't seem to understand that you're getting a full tower)

front panel clips seem a bit cheap, mine were not broken however it doesn't seem like it would take much to break them.

Overall Review: If you're looking for a solid full tower with room for all your goodies inside and doesn't look like something that comes out of a spaceship this is the case for you. Really solid and a great value.

Best Full Tower Case 1/19/2020 10:58:35 AM

Pros: I used the Corsair Obsidian 550D case for all my previous computer builds. The 550D was discontinued right after my last build. The 750D is slightly bigger, but in all the right places. Cable management is awesome. I don't think I have one cable crossing the top of my latest build. Plenty of room all around for system assembly, water coolers and lots of configuration options.

Cons: My only (very minor) complaint is that the 5.25 inch slots break up the cosmetics of the 750D case front a bit when you install an optical drive. Not a major issue though; it still looks OK.

Not a small case, but then I prefer mid and full towers for expandability.

Overall Review: My new go-to case.

Overall Review: rear exhaust fan burnt out the first time it powered up. Had to buy a new fan from a competitor. Front fan panel wont stay on . Had to glue it to case. That was on day 1

Quality control needs to go up, same problem with 780T with misaligned screw holes. 1/4/2020 3:32:10 PM

Pros: A very standard text-book full tower case with support for dual radiators (both front and top), but good luck finding the correct length screws for front mounted radiators.
Both HDD cages can be removed to allow extra fans / liquid cooling / direct airflow you name it.
Still comes with three external 5.25'' bays at this age, which is rare.

Cons: I am sick tired of having to use a file to expand the screw holes for both the power supply and PCIe slots EVERY SINGLE TIME, so they can line up with power supply and video cards correctly. It's a huge waste of my time and a pain to collect all the metal dust around during filing.
Those very same power supplies (mostly EVGA SuperNova 1000W/1300W) line up perfectly inside other cases like the Corsair 760T and Phanteks Pro / Elite so I know it's the quality control with this case and 780T.
Another problem is the removable front panel / dust filter that keeps popping when you work. Every time your hand touches the front it pops, I have also received a case with a broken latch that holds the front panel. Their solution is to put a long strip of tape over the top to prevent it from happening, but it DOES NOT work and makes it harder to push it back in place.
Finally what happened to the front fan/radiator mounting brackets? Why couldn't you guys make it a flat piece without all the ridiculous instruction and bends? With like 5mm thickness added to the bracket you essentially making lots of the standard radiator fan screws / fan screws useless because suddenly they are not long enough.

Overall Review: Please align your screw holes correctly because filing is not fun. Next time when you sell a case, please try to build inside it using everything you advertised (all size / thickness radiator you claimed in all those "supported" locations) to make sure it works as intended.

Best case I have owned in years.... 12/30/2019 10:08:27 PM

Pros: Been building my own pc's since the 1990's...my previous case a Silverstone FT01-B held two of my prior builds. Was looking for a more modern case with the same classiness found in my old Silverstone. This is a great case!

SSD's mounted behind the motherboard, brilliant!
Liquid cooling and fan options built in!
HDD vertical mounts !
Cable management made easy!
Solid construction...
Peg for motherboard mounting so you don't have to lay it down!
Easily removed dust filters!
Isolated PSU enclosure..
Vertical mounting option for GPU!

Cons: None so far...

Overall Review: Current build:
AMD Ryzen 7 3700X
Asus Crosshair Hero VIII X570
EVGA 1070 Overclocked
GSkill 16gb PC3200
4 X SSD's
1 X HDD
Corsair H115i AIO Cooling
4 fans

Highly recommended 12/16/2019 5:59:02 AM

Pros: sturdy, excellent layout, excellent cable control, slick doors. USB type-C on the front panel.

Cons: The PCI bracket openings are substantially restricted by the very clean looking structural supports. This is a problem for double-wide cards like GPUs. If you want to remove crossbars, make sure to do it before you've mounted the mobo.
The case does offer a GPU vertical mount option, but the required PCI-e extension cable is not supplied and there is no support other than the bracket side.
It could use more cable tiedown locations, especially ones wide enough for velcro straps.
it would be nice if the front panel was more easily removable.

Overall Review: Great case. I'd take a half-egg off for needing to cut a PCI-e bracket crossbar in order to keep my GPU exhaust unobstructed, but the rest of the cons are minor.
