5 out of 5 eggsvery impressed

Pros: Very good looking case. There are many places to mount fans 3 on top 1 on back 2 on bottom and 2 in the front. When all fans are utilized this case gets very good air flow and helps with temperatures. Enough room to mount my h105 closed loop liquid cooling radiator on the top in a push pull configuration even (why I bought this case) it is a tight fit for the fan connectors for the cpu on top, but it still does work. Case is well built and looks beautiful. lots of cable management space on the back (one inch). Every hole that you need for cable management. Full modular design, comes in handy cause you can decide where you want to put the hard drives. I personally took the 2 hdd holders off the bottom and mounted one below the 5.25 bays so that I can use the bottom 2 fans and give room for the 2 front fans for air flow.

Cons: The rubber things that go on the top are too thick and cannot be in if the screws are to mount the radiator on top. Had to take them out.

Other Thoughts: Awesome case I would recommend this to anyone.

4 out of 5 eggsCame in with broken parts

Pros: So many pros about this case. It has air flow, desired room for liquid cooling, and a lot of drive room. Cable management is very do-able with a modular PSU but it has some kinks to work out. But overall it's a magnificent case.

Cons: Biggest problem was when it got to my house, I inspected the case and i noticed the clicking locking mechanism was broken on one side and one of the front fans had a broken fan blade. Another problem was the fact that the design of the case was not too SATA cable friendly because I had to kinda battle the case to fit the proper SATA cable arrangements.

Other Thoughts: I actually sent an RMA to Corsair for the broken parts and they did not hesitate to give me new parts. Their customer service was a piece of cake and I'd happily represent their products in the future. Lets just hope the SSD's they have up are much more pleasing than my first experience with this case.

5 out of 5 eggsAwesome Case

Pros: Very Nice sleek looking case has plenty of space and will fit my build and I don't think I will need to go larger.
Build quality is very good has a very solid feel to it.
Love almost everything about it and it screams quality Just buy it already.

Cons: The one thing that keeps this case from being perfect but wasnt enough to loose a egg is the use of the thumb screws for the side panels. I was really hoping for some type of button release, however it still would not have changed my decision. I hope maybe in the future they will do a revision of this case with a swing open side door or maybe even a button release. However for some this may be a plus because it will be secure once it is on.

Other Thoughts: I hate making decisions like this online because things are not always what you expect when they show up on your doorstep, however the case exceeded my expectations. For days I was torn between the 750D or the 900D and was even considering the fractal and nzxt cases. As soon as I opened the box I knew I made the right choice. I just didn't want to invest 300.00 in the case but wanted something very beastly looking with plenty of room for watercooling,sli and future upgrades. I can't see needing more space than this unless your building a doomsday ultimate gaming/server rig for pure overkill / show.

5 out of 5 eggsCorsair 750D

Pros: Very nice case, not to huge but still pretty big if your not used to a full sized case. Lots of room for my water cooling loop. Decided to get this instead of the 900D cause the 900 wouldn't fit under my desk. Very happy with the purchase, although there is still that side of me that wants that 900D!

Cons: The SSD mounts seem a little flimsy to me. If you so much as touch one of them it will fall out of place. Not enough to take an egg away in my opinion but something to note.

5 out of 5 eggsCorsair Obsidian 750D Black ATX Full Tower Computer Case


-This case, as well as many other Corsair cases, just looks sleek and simple
-Modular epicness
-The dust filters are genius. There is never dust in my case. Like ever.
-So much room for air flow, cable routing and management in the back is beyond sufficient if you know what you're doing. Everything fits perfectly.
-Modular drive cages are very nice. SSD cage in the back is nice as well, though I still installed my SSD into the Drive cage.
-Yay, Stand-offs
-All fans and radiator fit beautifully (using all 140MM fans except for the two 120's with the H100i)
-I think most Corsair cases have these now, but the stand-off "guide" to get the motherboard securely in place is wonderful.
-Fully windowed side panel, FTW. I can see everything inside of there, in all of it's green glory.

Cons: None.

Other Thoughts: Literally everything just snapped right into place. This is definitely a builders dream case. All parts fit beautifully with room to spare. Absolutely going to add another GTX 780 FTW gpu because there is more than enough room.
I get so many compliments on how nice my new build looks.

5 out of 5 eggsVery Solid Case

Pros: - Lots of Space
- Solid Build Quality
- Huge Side Window
- Moveable Hard Drive Cages
- SSD Mounts
- Water Cooling Capability

Cons: - Side Panels are a little difficult to put on
- Front dust filter doesn't fit well
- Front fan mounts are difficult

Other Thoughts: This case has a lot of room, is rather heavy, and is very solid. The side window is very large, almost a little too large, you have to be very careful where you hide cables. The moveable hard drive cages make the front of this case very versatile. The four SSD mounts behind the hard drive cages not only make great use of space, but also make your build look even cooler. They do make it difficult to plug power into the SSDs though. This case has a lot of potential for water cooling as well; radiators can fit in the front, the top, the bottom, and event the rear. Plus there is plenty of other room for reservoirs and pumps. Now for my complaints. I really wish the side panels were easier to put on. They are easy to put on when the case is on it's side, but standing up, you need one arm to hold it in place, a second arm to push the panel closed, and a third arm to put the thumb screws in. My front dust filter is bowed out in the center, which makes it a little useless and a little difficult to insert. My last complaint is that the front fan mounts are a little picky. While very easy to mount, the screws are very short and when I tried to install a different fan (I was hoping to get a LED glow out the front, didn't work), they ended up not being long enough. I fixed this by drilling out the fan, letting the head of the screw sit about half way into the fan. The screws did work fine for the Corsair fans that came in the front though.

Overall, this is a very solid case with plenty of room and expandability. I really like the quality of this case.

5 out of 5 eggs

Pros: Easy to assemble, very clean, beautiful

Cons: I can't put a double thickness drive into the 5.25" without bending a little metal. I have an LTO tape drive for backups.
