Obsidian Full Tower Case

Case Accessibility

Easy to Build, Hard to Beat

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 even fun. Corsair Obsidian Series cases are designed by system builders, for system builders, for the sole purpose of building truly extraordinary PCs. Rugged steel meets the subtle elegance of brushed aluminum in these world-class PC cases designed to be the foundations of amazing systems.

Corsair Case Design

Minimalist Style, Maximum Potential

The 750D Airflow has a clean, elegant exterior that dispenses with arbitrary plastic add-ons in exchange for the beauty of 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.

Amazing Cooling Possibilities

High Airflow Path

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.

Corsair Fans

Three Included Corsair Series Fans

Great airflow doesnft have to be noisy. The fans can push good amounts of air across your hottest devices with less distracting fan hum, and the direct airflow design of the 750D provides an excellent path for cold air to get to your hottest parts. This case comes with 3 fans included, at the front it hosts two 140mm AF140L fan and at the rear is a single 140mm AF140L fan.

Liquid Cooling Capable

Watercool Your Graphics Card and Processor

The 750D has room at the front, top, and rear for radiators, allowing you to quiet down your GPU and CPU with liquid coolers, this also allows you to get better overclocks out of your components for better quality gaming.

Chassis Airflow
Chassis Airflow
Date Issued: 20th Oct 2008

The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

Date Issued: 19th Jun 2008

Watercooling for the PC has been around for years in some form or another, for at least as long as Scan have been in business, with basic physics defining why you want to use it. That means for air cooling, to cope with increasing temperature in the heatsink you need to move the air across it faster. That is why thermostatically controlled fans in your PC will turn faster the hotter something gets.

Corsair Obsidian 750D Airflow Edition Black Full Tower Chassis with Window, Aluminium/ Steel, 9x Expansion Slots is rated 4.7 out of 5 by 24.
Rated 5 out of 5 by from Rhis case has enough space and drive base for the most demanding of builds This case has plenty of space for 9x HDD if fitted with the caddies one on top of each other including an extra caddy (optional) plus 4x SSD bays. Plenty of gromet openings for cable management, 2x140 fans in the front which push in plenty of air and 1x140 fan in the rear as exhaust plus 2x optional 120 fans at the bottom and 3x 120 optional fans in the bottom so, air flow is optimised. A 280mm liquid cooler can be fitted at the front or top and a 360mm liquid cooler can be fitted at the top but will have to sacrifice the top 5.25 drive bay. All in all a very spacious case with excellent air flow.

Rated 5 out of 5 by from All the space you need! Thihs case is my first full tower case and I'm not dissapointed with it in any way. I was using nzxt's H440 which is a mid tower so there is quite a size difference but its much needed size difference if you like to have space for air to flow without feeling your GPU and other peripherals arent squashed up. I have an ATX motherboard which looks fairly small in this case but I have a asus strix 1080ti and its length in the nzxt H440 was a tight fit, but in this case it feels right at home with space! the case has good openings for routing your cables and has ample room if you like to use lots of hdd's! I personally have removed all the hdd bays as I use m.2 ssd's what go on the motherboard so it saves space and cable organising. I feel the cables for the front panel could have been a bit longer but they reach for what I need so it all works. This truly is a airflow case and am happy with my purchase

Rated 5 out of 5 by from Excellent no-nonsense high airflow case, great for gaming! Ok sure it's not the flashiest looking case ever but it does an excellent job at keeping high end gaming components cool. Being a full tower the is plenty of room inside for even the bulkiest of installs. With a mutlitude of different radiator install solutions pretty much any AIO water cooling setup would be supported. And you could even build a full water cooling loop in this system If you wanted to go that far. My only con would be that it looks a bit ugly if you have an optical drive as it the opitical drive bay doesn't come with a surround to match with the front facea. And when you take both sides off it's not the most rigid structure I've ever felt. While picking it up and laying it down when building the rig I definetly felt it flexing and twisting slightly. This pretty much goes away when up get both sides back on. And on the flip side of the coin it does mean that it's pretty light. It doesn't feel as solid as my LianLi case I had before but it's definitely much lighter and has better airflow.

Rated 4 out of 5 by from Large modular design, loads of space at a good price Spent some time searching for a case which would tick all the boxes, without spending a fortune. I really like the airflow on this case, pulling in the front and exhausting out the back is excellent for cooling. The leads on the front fans need to be longer though, you cannot plug one of the front fans into a fan header at the back of the m/b, it won't reach. It has nice cable management with protective edges for you to route your cables behind the motherboard, although you do find that with 6xSATA disks and 2xSSD's it does get quite tight quite quickly. Right-angled SATA connections for the 3.5" bays are a must. Leaves the main case free of cables to get in the way. Can move the 3.5" bays about to accommodate your needs, or remove them completely if you only use SSD. The SSD mounts are a little fiddly to clip into place though. 5.25" quick release mounts will only work with full length devices, if you put a shallow device like a card reader in, you'll have to use screws. Can't comment on using this rig with water cooling as I don't have it, but there was more than enough space for all my disks and a large cooler on the CPU. My only minor gripe is with the HDD brackets, if you stack two on top of each other, rather than both on the bottom then the metalwork is a little flimsy and the cages do move about a bit. You'll only need to do this if you want all 6 disks directly behind the fans, or want to have 9 or 12 disks fitted (!!)

Rated 4 out of 5 by from Great Case, with some silly designs The Case came undamaged but not the best packing ever. would be nice to see a bag over the case to stop metal finsh wear. my only real issue is the radiator support as it cannot take a tripple rad without removeing the 3.25" bays. would be nice to see a more modualr system so you can remove 2 but have the third bay clear of even the thickest radiators.
Date published: 2018-02-05
Rated 5 out of 5 by from Quality build, LOADS of space. Well, managed to shift my old system into this, only problem was a black lead from the front panel which doesnt connect anywhere on my board. so i lost 2x usb operation on the front. but my boards a little out dated so perhaps it will work one day when i upgrade the board. also had to buy a fan splitter for the x2 case fans on the front. Other than that really pleased with it, its a beast. dust mesh on the front\top\bottom are great, especially with pets around.
Date published: 2018-01-10
Rated 5 out of 5 by from Good, lots of space As well as being large it also has cable holes and grommets that support clean cable management. It has two case fans, with separate motherboard fan cables. I bought a fan splitter-cable separately. My single motherboard fan plug can now support both fans with no issues. Headphone + mic sockets are tight fits, slightly more than I'd like but they definitely won't pop out when you lean back.

Rated 5 out of 5 by from Great case, stacks of room I needed a case that was great for airflow and great for upgrades in the future. Searched high and low for a case, was looking at the cube style Corsair cases but their width put my off. This case came to my attention. Lots of room for drive bays, which just pop in and out, Really good for cable management as there is loads of space behind the motherboard. The fans that come with the case are quiet, 3 x 140mm. My only issue with them are they are plain. No RGB lighting or anything like that so if you like that kind of thing you may want to upgrade your fans. Plenty of room for even the biggest GPU's too. I have a particularly hot GPU the zotac gtx 1070 AMP! edition...which before the upgrade would get to 80 degrees c. Now however, my card hasn't hit any higher than mid 70's, Airflow is great with this case. Plenty of room for radiators too for watercoolers. Would recommend if you have the money for it as my only negative is the price.

Questions & Answers

Does the case come with LEDs attached?

Many of the promotional images show blue LEDs fitted to the case. Are these a feature or just for show?
Asked by: jHart
No, other than the Power On and Disc Busy LEDS at the front. These are both white. Both my Airflows have blue LEDs now, but they are on the extra Fans I retrofitted.

need to be sure that this case will take corsair h115i cooling unit

not sure on gpu cooling unit but been looking at this sureArctic Accelero Hybrid III – 140 will there be room? any advise will be really helpful
Asked by: jay74
Hi jay74, this case easily fits the corsair H115i cooler, I know this as I use this cooler in the case. I have the radiator mounted at the front with no problem provided you dont need the drive bays in, and if you do then I think this would easily house it in the roof of the case
