5 out of 5 eggsSpacious, sleek, this is a thing of beauty.

Pros: -The 750D is bigger than other full towers I've previously owned, slightly wider, a bit taller. The feet on the four corners raise the case up about an inch for psu air breathability.
-The removeable ssd brackets give me the choice to use it or lose it.
-two hdd racks (3 bays each) can be used in a variety of positions in the case or can be removed completely.
-5.25 bays are very easy to use - no screws needed.
-The black aluminum face is very sharp, modern, and professional.
-Plenty of space in this case for big air upgrades and/or custom water cooling applications.
-The case is very sturdy and does not flex or bend while putting pressure on anything (while installing a new card in a tight slot for example).
-Superior cable management makes it easy to hide all those cables and open up the case for better airflow and an overall excellent view of the components.
-air filters over the main fan areas.

Cons: -I wish there was a possible option for easy running a second psu.
-If the 5.25 bays could be positioned elsewhere.
-The main power rail for the motherboard is pretty fat, so putting that side cover back on required a little pressure to smash everything down (but the cover doesn't bulge, so it's not a big worry).
-The bottom front fan wire isn't long enough to reach my motherboard if I use the cable management system to hide it, but this is a 'fan it came with' problem - not the case per-se.

Other Thoughts: I have a second psu custom mounted in the bottom front of the case so I have a dedicated separate psu for auxiliary systems (water cooling and lights). I cut most of the wires off, but left the 'power switch' wires and 2 rails for auxiliary systems. The power wires are connected to a tiny 2 way switch that I have fixed in the center bottom. It looks really nice there, but it would have been easier if there was a small port somewhere dedicated for running a custom wire out around those front fans.

As thin as the top and bottom mesh plates are, they are incredibly strong. I am well impressed with this case. Not one bit disappointed!

4 out of 5 eggsCorsair Obsidian 750D Black Aluminum / Steel ATX Full Tower Computer Case

Pros: Lots and lots of room. There is enough space for any enthusiast to build the rig of there dreams. Cable management is nice in the case as well.

Cons: Weird mount under the hard drive cages. In order to install a fan there you need to take the cages and the mount out, this means you can't have a fan under the hard drives. Besides that excellent case.

5 out of 5 eggsBest case i have ever used/seen

Pros: Large enough to fit more parts than most people use, but fits under the table im using as a desk. Cable mounting is the best thing to come to cases and this case is almost perfect. HDD mounting cages are re-configurable, good thing as i had to remove one to fit my PS. Dust filters are the main reason i chose to upgrade to a new case as my gpu/cpu kept needing cleaning. Fans are very quiet. Steathy with no LED fans.

Cons: None of the Cons are enough to - a egg. Its not the 900D, but its half the price for 60% of what the 900D is. Fingerprint magnet! After building, try not to touch it.... Had to buy a CPU power cable extension. Not the cases fault as i got my PS with a smaller case in mind.(routed the cable over my gpu/mobo untill i get a extension) With just the basic PC part list, the inside looks sad and empty! The cover on the front indeed blocks free air flow some. Not enough to be a big deal unless your parts are overclocked. My temps are fine with i5 2500k and a 580gtx both stock clocks. Never gets over 60c on the cpu. Never gets over 65c on the 580gtx with custom fan profiles set with Afterburner. But when ever corsair has the replacement mesh front cover available, i will be picking one up. Static pressure fans might help out on this point though. If you want, you can find the same case with the mesh front cover already installed.

Other Thoughts: Almost got the 450D but my budget allowed for a slightly bigger case so i went with this one. Going to use this case as a HTPC/file server after i build my next computer.

4 out of 5 eggsBang for the buck

Pros: Lightweight, stylish, great compatibility with WaterCooled systems, large gpu and massive storage

Cons: 1 of the HDD Receptacles came a tiny bit bended (nothing serious i fixed it myself)
When installing a large psu one of the cable management brackets is obstructed. (I installed an EVGA PS2-1000

Other Thoughts: Overall a great case, easy to handle, and lots of space inside for various gps, hdd, and cooling systems.

5 out of 5 eggsI am really nit-picky but this is impressive

Pros: - Very nice looks. Can easily be a work or gaming PC case.

- HUGE. What more can I say about the Obsidian Series cases? They are absolutely enormous. Holding 10 fans, 3 GPS, 3 HHDs, 4 SSDs, PCIe SSD and still room to spare, it is absolutely amazing as far as space

- Cable Management. I wish there was about a half inch more of cable management room, and I don't think that would have been too hard to do. With 7 storage drives and 3 GPUs, cable did get a little excessive and difficult for me to manage in a few instances. However I do not believe this would be the case with most builds. Mine is a little... okay A LOT... on the overkill side, but I do everything from work to video editing to gaming on my rig so I needed to go overkill. Back to cables, even with all the cables running to my components, I still have plenty of room behind my motherboard tray to route cables... more so than I expected.

- Side Panel Window. I have seen way too many gaming rigs with so many LEDs that it hurts to look at the PC and you want to ask the person who made it why they built such an eye sore. Personally I find that the smoked tent to the window on the 750D is absolutely perfect. I use BitFenix Alchemy Blue LED strips (2 of the 30 cm ones) and I find that it lights my case up absolutely beautifully. Not too much but not too little.

- SSD Mounts. I love how Corsair made the SSD Mounts in this case. They are out of the way and you can still show them off through the side panel of your case. However, please see the CON section of this review for my gripes.

- HHD Cages. I am not one who likes to see HHDs all over the case, and while I wish Corsair had done something similar to Case Lab's SMA8, I find that the ability to move the cages around gives you plenty of ways to customize your layout and still give you good airflow and therefore temps. Keep in mind that the cages in their default location cover up 2 120mm fan slots that I highly recommend uncovering for better airflow and remarkably good temps on air cooled GPUs.

- High Airflow Kit. I bought the High Airflow Kit to go with my case and I find that it makes the system quieter, cooler (if running the right fans, I personally use 140mm blue Spectre Pros)

- Dust Control. Well... its pretty good where filters are included, see CON section for more.

- This ones a stupid one, but with mine, I have 2 LED strips inside. One on top and one on bottom, running the length of the case (30cm BitFenix Alchemy LEDs are perfect). With the ventelation in the back of the case and the case being at a 45 degree angle to the wall, the LEDs cast a very neat effect on my wall. Combined with 2 short LED strips on the back of my desk and my portable gaming rig to my left on my other desk, my room looks totally awesome, so job well done Corsair!

Cons: SSD Mounts. While I do love how they included these, I accidentally broke one when inserting an SSD (my fault for not knowing how to use it but i still feel like they could have been a little stronger) And if the drive has a design on the front like the skull on the Intel 730 Series SSD's they are as upside down as upside down cake! Not a huge deal if you are not picky, but I think my set up would look so much better if I had the ability to look at my SSD oriented the correct way.

- Dust Control. I really wish that if case manufacturers are going to include dust filters, they start including them for ALL fan locations. I personally have 2x140mm front intakes, 2x120mm bottom intakes, 1x140mm rear intake and 3x120 exhaust. My PSU has the fan facing down to pull in cool and clean air through the filtered intake. Well... only the front intakes and the exhaust are filtered... where does that make any sense??? I will be ordering some dust filters in the future to take care of this situation even though my case doesn't get too dusty, and when it does I have an air compressor barely two feet away.

- Side Panels. Okay, I don't know what happened here. I never did like those older cases that had the metal prongs you had to get in the holes and if one prong got bent the entire panel got stuck. Nor did I like the ones that simply slid on and was held by a latch in the back. Both had a bad tendency to get stuck. I DID however like the handle model Corsair had on the 780T. I really wish they would have done the same thing on this case, but unfortunately they didn't. The side panels on this case simply slide on with nothing to grab on to whatsoever. If you don't use the thumb screws to secure them in to place, they will simply fall off.

There is a hole right below the bottom rubber grommet for cable management. I am assuming this was meant for running Hard Drive cables through if you left the cages there. However, there is no grommet on this hole at all, and if you move the cages you have this big gaping hole for no reason. Kind of ruins the aesthetics of the interior of the case, I think. However I was able to solve this by using the NZXT USB Expansion card. My motherboard doesn't have enough internal USB headers so I was forced to buy two of those cards. Covers that gaping hole up with room for the cables to run right between them.

Other Thoughts: I know it looks like I have more negative things to say than positive. Let me assure you that I had to REALLY nit pick and that this is by far the BEST case I have ever used. If I would have had the money (I was on a budget when I built this machine and the components came before the case) I probably would have gone with a Case Labs SMA8 or SM8. However, this case is unmatched at this price point and will be an EXCELLENT choice for anyone who is needing plenty of room, cable management, and cooling. This is hands down a case I will be using for quite some time and I hope that Corsair continues to deliver in the future.

Two more quick after thoughts...

This case, when packed with GPUS, SSDs, HHDs etc, does tent to get extremely heavy. I wish there was a way to add wheels to this case. Fortunately I have a rolling shelf that I have mine sitting on so I am content.

And secondly, if you have cats, make sure to find a way where they cannot get on top of this case. I have two cats who absolutely love to sneak in when I am not looking and nap on top of this case where my radiator is.

4 out of 5 eggsOkay

Pros: -Big, can fit anything in here.
-Glass Window is nice
-came with the appropriate Mobo mounting screws
-Removable hardrive/ssd cages.
-Magnetic fileter
-Good stock fans and good airflow

Cons: I the 2 things i dislike are:
1: There are aot of screws and even though they label what screws look like in the instructions its very hard to see what ones goes where. Would have been nice if they labeled the bags they actually came in.

2: The most annoying thing is after having this for about 2-3 weeks one of the two leds on the power button doesn't work anymore. Granted i could buy another led and replace it. But common 2 weeks and its broken already? Both of these are annoying enough to - 1 egg.

Other Thoughts: Either way this case is a solid build for anyone! A little pricey but no biggy, i knew exactly what i was buying and what i would get. Good job Corsair. I'm almost never disappointed with you!

Current Build w/ this case:
G1 Gaming 960 4gb
2 Seagate 1tb hardrives
1 Asus optical drive
Hyper 212 Evo Cooler
MSI Gaming 5

5 out of 5 eggsNice case

Pros: This case is awesome. It has plenty of bays for SSD, mechanical HDs, a lot of space behind the motherboard tray for cable management. I am getting good airflow and having to do any work inside the case in a breeze. It also looks great!

Cons: None

5 out of 5 eggsBest Case hands down

Pros: Some will say this case is overkill, and they may be right, but it has extremely good airflow. Front mounted fans under the panel create great airflow yet they stay hidden from view. Dust covers over the fans are amazing! the magnetic panel on top allows you to mount a cooler, yet it keeps the screws hidden from view. The case has a very clean look to it. It can hold up to 3 gpu's so it is very future proof. When I saw the case for the first time I was hooked, and ever since finishing my build I am even happier I chose it!

Cons: Absolutely perfect in my opinion. Does not look at all like some cheap childish looking cases.

5 out of 5 eggsSo much room!

Pros: Space available.
Comes with fans and easy to clean filters.

Cons: None.

Other Thoughts: I needed this case to add liquid cooling to the mix and this has enough room for more than just one radiator, I was so cramped in my ATX-mid tower and now I have so much more room I don't know what to do next???
