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.

Great case, tons of room and easy to build in.

Pros: -Motherboard 'peg' in place of one standoff to keep your mobo in place while you screw the board in
-tons of space for custom watercooling loops, multiple AIOs, or open airflow builds.
-filters on all fan areas help keep your build clean.
-modular drive trays for as many (or few) drives as you would need in a non server build.
-Tool-less 2.5, 3.5, and 5.25 bays make it easy to swap drives
-TONS of space on the backside of the motherboard tray for cable management (lots of cable tie loops as well)

Cons: -Included fans can be pretty noisy at full speed.
-USB2 Motherboard connections have a bit of multicolored wire at the connection point (nothing crazy but it is noticeable)
-windowed side panel could be built more rigid as it can flex quite a bit when not attached to the case
-foam in shipped box is low quality and not good for packing a completed build without extra support

Overall Review: Would definitely recommend to any new builder or someone that needs lots of room for custom water cooling! This is an extremely spacious case making it very easy to build in. It has a clean obelisk look to it with lots of breathability for air cooled builds and lots of space for any liquid cooling configuration. I personally couldn't be much happier with this case.

Great Case! A lot of space and good airflow

Pros: -A lot of space
-Good for cable management
-Good airflow throughout the entire case
-Comes with 3 fans although not the best fans my temps are pretty good running a 3900x + 2060super OC
- Motherboard standoff screws

Cons: -The see through side door is very squeaking when any force is applied to it, luckily that doesn't really bother me since I'm not constantly moving it.
-Front panel is kind of loose its supposed to latch on but it wont stay on properly.

Overall Review: Would recommend this case to anyone who wants a good amount of space for expansion and wants good airflow. Aside from the squeaky panel and the front panel not staying on properly(I had to tape it) it is a great case overall.

Front panel clip was broken

Pros: Plenty of space for neat and tidy installation with plenty of airflow.

Cons: Noted upon completion of the computer build that the front panel that protects the fans would not clip into place. The retaining clip mechanism was broken when the case was received.

One of the best PC cases I've ever used

Pros: - Looks nice and professional
- It has plenty of room for things like a liquid CPU cooler and a long GPU
- Organized: The different sets of screws were in separate bags. Also, the case allows good cable management, allowing you to route most of the cables and chords behind the motherboard so they don't clutter up the case above the motherboard too much.
- Screwless installation for 3.5" and 5.25" drives makes installation of drives fairly easy
- It includes real expansion slot brackets rather than pop-out throwaway placeholders that many other PC cases come with
- It comes with 2 front fans (140mm) and a rear fan (most other caeses only come with 1 front fan, and some don't come with any front fans at all). The fans are quiet.

Cons: - The front panel is supposed to latch in place, but it doesn't stay on very well. I contacted Corsair and they replaced my front panel for free.
- Cosmetic: If you install an optical drive or card reader in one of the 5.25" bays, the front of the drive isn't flush with the front of the case
- Know what you're getting into: It's a big case and might not fit well on some computer desks.

Overall Review: I recently bought this case for a new PC I built for myself. I wanted something that had plenty of room for a liquid CPU cooler and fans and airflow, and this case delivers. Also, the size makes it easy to work on inside if you want to replace or upgrade something. Just know that this is a big case and might not fit well on all computer desks.

I installed a liquid CPU cooler to the top of the case using the long fan screws that came with the cooler. I put the fans on top of the radiator, with the long screws going through the top of the case, through the fans to the radiator.

Corsair Obsidian Series 750D Airflow CC-9011078-WW Black Brushed Aluminum and Steel ATX Full Tower Computer Case

Pros: It is big, if that is what You want.

Cons: I wish I had never ordered this case. The front panel will not stay on and I didn't realize it had a glass side. Not sure I will ever use it.

It fulfills its purpose of great Airflow

Pros: - that thing is a wind farm. I have it configured to have two intake 120mm fans on the bottom, two 140mm fans in the front, two exhaust 140mm fans on the top mounted to a radiator, and one 140mm exhaust fan on the back. This creates a positive pressure air flow, keeping the dust out (more air enters then leaves)
- it had motherboard standoff screws, so you won't fry your motherboard as some people forget to install them
- great cabling management, due two second plane that allows you to have the cables pass without being exposed
- lower bay removes, allowing to install the two 120mm fans
- due to its size there is lots of space inside
- solidly build, you can tell it was well made

Cons: Minor things:
- I don't care much about the front SATA bays, and there is no way to remove them
- It weights quite a bit with all the components installed, so don't think you are going to be moving it around much
- It does not have dust filters for all the fans (I purchase a dedicated DEMCiflex Dust Filter Kit for this case)

Overall Review: I spend a considerable amount time researching best airflow cases , and this was my finalist. While it is not most ascetic case out there, (shiny lights don't mean much to me) it comes with superb airflow.
