Frequently Bought Together
Product Overview The Obsidian Series 750D full tower PC case combines generous expansion flexibility, room for advanced cooling options, and an interior that’s optimized for fast and easy builds and upgrades. It 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. And, it incorporates a host of clever system builder-focused features, because building a system should be straightforward, trouble-free, and even fun.

The room you need when you’re getting serious
Nine PCI-E expansion slots support double and triple GPUs. There’s room for up to ten drives, and four USB ports on the brushed aluminum front panel.

Your system. Your cooling.
The three included Corsair AF140L high-airflow 140mm intake and exhaust fans are custom engineered to deliver excellent airflow with less unnecessary turbulence and noise. You can mount up to eight fans, with room for dual radiators on the bottom, front, and top.

Take control of your storage
There are four separate mounting locations for the drive cages, and if you’re moving to 100% solid-state, you can remove the 3.5” cages entirely and use the four side-mounted 2.5” cages.

Designed for fast, straightforward builds
The side panels and expansion slots use thumb screws, and storage installation is tool-free. A center-post standoff holds the motherboard in place while you secure it, and the dust filters are easily accessible and removable. Our innovative cable routing system has multiple cutouts with rubber grommets for superior airflow and a cleaner look, and the CPU backplate cutout lets you install or upgrade your CPU cooling without removing the motherboard.

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.

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 Black Full Tower case Aluminium Steel with Side Window 3x140mm Fans USB 3.0 E-ATX/ATX w/o PSU is rated 4.6 out of 5 by 27.
Rated 5 out of 5 by from Fantastic case I couldn't be more pleased with this case. It is a joy to work with. Cable management is fantastic. Temps have dropped 15 degrees from what they were in my old case.

Rated 5 out of 5 by from Looks great but big! This case is fantastic so much room inside room for multiple hard drives 2 graphics card water cooler anything you want basically fantastic purchase.

Rated 5 out of 5 by from Corsair build, Corsair quality You cant have a bad Corsair case. The no tool designs are amazing and really help with the build. So many tie downs and grommets to hit zip ties and secure cables.

Rated 5 out of 5 by from Exactly as described Corsair's 750D is exactly the big case it's described as. Plenty of room inside for whatever you've got to put in there. Some fiddlesome clips to remove front panels for DVD drives and such like. One missing feature, which I don't require (hence the 5 stars awarded) is a HDD hotswapable bay. Fans are whisper quiet too!

Rated 4 out of 5 by from Just short of perfection. There's not a lot too be said about the 750D that others haven't already said, but I'll try to talk about some of the good and bad of the case myself regardless. First, let's start with some of the negatives (There are very few, honestly.) Negatives: -Using a Corsair H100i radiator at the top of my case, despite them both being manufactured by Corsair the screws on the H100i stick out of the top too much and I find they dent the magnetic dust cover on the top. -Some of the items in the case are done in a bit of a strange way, makes it hard to position some things and meant it was a bit difficult to fit new fans in the front of the case. -Stock fans are pretty loud and a bit poor, may want to change them. I can't really think of many other negatives, so if those things don't bother you, you're in luck with the laundry list of positives for this case: Positives: -Sleek, minimalist design, with brushed aluminium front panels that adds an amazingly simple and classy look to the case. -Tons of space. I'm currently using this with SLI 980's inside and there's still enough room to swing a cat in there, but not so much extra room that it starts to look ridiculous unless you add in some watercooling parts, it's really a perfect size. I removed one of the drive bays because I only needed one and I figured removing it may help with airflow and cable management, but it's absolutely not necessary. -Stays cool. Very cool. Not only does this case look cool, but with a H100i on the CPU and replacing the rather noisy and slightly poor fans on the front with two Noctua AF-N14's for intake fans + a quiet edition Corsair AF140 on the back, it stays almost silent even when running all fans at 100% and everything stays very cool. I can't really think of much else to say about this case, but I certainly reccomend it to anyone considering it, so long as the few negatives at the top don't deter them.

Rated 4 out of 5 by from Good, but not perfect. I wanted a well built, good looking case for my new rig and this was my choice. It was very easy to build in as it has plenty of space, options and great cable management. However, there are a few niggles. First is there are no damping pads on the psu mounts and second, no dust filters on the bottom fan positions. Neither is enough to spoil the overall result though and I'm very happy with my choice.

Rated 5 out of 5 by from Just Crying to be Water Cooled! Fantastic case, lots of room for watercooling, good build quality and keeps components very cool. Bought the case with only air cooling in mind but after building my build and seeing how much room is left i am certainly going to be putting in a custom watercooling loop. It supports up to 360 rad on the top, 280 on the front and 240 on the bottom, though unsupported you can fit a 420 on the top but you have to bend a bit of metal in the top 5.2 inch bay. i think i made a good choice with this case and i am a very happy customer, thanks Scan and Corsair!

Rated 5 out of 5 by from Cosair Obsidian 750D Full Tower Case What a case. You can not only get inside, so much room, the cables are all hidden in the back. no messy cable to get in the way. 6 hard drive bays 4 SSD drive bays, and with the motherboard and Power supply you still have room for a London bus and taxi cab. I added the Corsair H80i water cooling system. When up and running I had to keep checking if the PC was on, absolutely no noise, just a very very slight hum if you listen for it. The best choice I ever made.

Triple rad in the top??

Will a triple rad fit in the top of this case?? More so a Thermalchill PA120.3 rad... I'm trying to find something that will house my EVGA 759 and 762 boards.. I was hoping this one might get them in!!
Asked by: Phill
triple rad could but it will take up spaced used by the dvd/bluray drive units.. I used a duel rad and that's perfect for my build
