4 out of 5 eggsMy cup of tea.

Pros: This is a nice full-tower (but not obnoxiously tall) case with tons of space. The mounts on the top make adding a Corsair H100i cooler a breeze. Fans are not too loud, but I may try some Noctua fans in the front. Removing the HDD cage was a piece of cake and the SDD mounts hold the drives securely enough (still wiggle, though). The many cable grommets are really nice.

Cons: The side panels will not stay put on their own without being screwwed in. I think this is totally silly and a real pain. Also, the thumb screws for the panels seem cheap.

Adding an optical drive sort of breaks the clean aesthetic lines of the front panel.

Other Thoughts: Been using LianLi and Cooler Master cases forever and this is my first Corsair case. I really like the aesthetic design and builder-friendly features.

It's all black. It sucks the light from your room. Make sure you have a headlamp during your build because it's impossible to see anything! (I suppose if you are in your 20's you will not notice this.)

5 out of 5 eggsHigh Quality / Customizable

Pros: Very well built! Great airflow and tons of customizable options for case fans and radiator placement. Nice high quality material (for the most part) easy to open side panels (had that problem with my cooler master haf 912). I love the full see through window, it really shows off your PC. Plenty of room and really well thought out cable management (even with evga 1000w modular psu, which people were complaining didn't have long enough cables for proper cable management). No issues hiding cables behind and keeping everything out of the way for airflow. Running an i7 4790 at 3.6ghz idle is 36c with a 240mm radiator in the Arizona heat

Cons: Front panel is plastic and a bit flimsy. Panel has a click button to open, similar to an entertainment glass door with magnets. Kinda cool, but also opens by accident easily when moving the case. Also wish it came with dust filters for the bottom two 120mm fan slots.

5 out of 5 eggs

Pros: A big roomy case ready to fit nearly anything you want to throw in it. About an inch or more of cable mgmt. space as well as many places to tie the cables down. This makes the case look neat and tidy.

Cons: The filter under the power supply would rattle something fierce. Easy to fix the noise with a little tape to anchor it.

5 out of 5 eggsCorsair750D

Pros: Large, Ton of Fan Options, CPU cooling options, great airflow, can't believe the amount of drive cages...could use this for a server if you wanted!

Cons: NONE!
Except maybe would be cool with LED lighting...but that's easily and cheaply fixed.

Other Thoughts: Will be adding more Fans...sticking with Corsair...but not required. Red Interior Theme.

3 out of 5 eggsGood Design, Cheap Materials

Pros: Excellent design and fantastic interior and exterior look.

Cons: The frame of the case is solid and well built. However the pannels are flimsy and cheap. the front pannel that covers the dust filter looks nice but is terrible. It's hard to get it to sit evenly and it's mostly plastic. The side pannels are similar. They would probably break easily with any rough handling.

Other Thoughts: This is a perfect example of a well thought out design with cut corners in regards to cost. I like it when a product is made out of solid parts, not cosmetically appealing but flimsly and cheap parts. On the bright side, there are some really well thought out features here. It's a good thing for that though. Otherwise I would give it a 1 egg rataing. I'm a big Corsair fan and I do like this case but it is not exactly on par.

5 out of 5 eggsNice case!

Pros: Big enough for super high-end equipment without being ridiculous.
Flexible drive mounting system.
Excellent cable management.
Great airflow.
Included fans are quiet while still able to move a decent amount of air.
Huge side window.

Cons: The only thing I don't like about this case is the gap behind where one of the drive cages are mounted as shipped. It would have been nice if it had a grommet or something. Not a big deal at all, but that's the only thing I could find.

Other Thoughts: This is easily the simplest case to build in that I've ever worked with. I've very happy with it.

5 out of 5 eggsGreat case

Pros: -Insane cable management capabilities
-More than enough space!
-Very classy and modern appearance
-Everything feels of quality
-Definitely engineered with the gamer/enthusiast in mind
-Future proof
-Awesome case for positive pressure

Cons: Not necessarily a con, but the window panel is fairly flimsy. The plastic itself is insanely clear though, just be careful with it.

Other Thoughts: This is an upgrade from a thermaltake V6 mid tower...and all I have to say is I'm never going back to another case. Corsair is a great company and I have always been pleased with their products. Except the M65 gaming mouse, it's too small. :P

5 out of 5 eggsGreat Case

Pros: This is a great case, it is well made and solid. It has phenomenal amounts of space behind the motherboard tray, and is nicely configurable depending on your storage needs. Its all painted black and the rubber grommets for cable routing big and its easy to hide all your cables.

Cons: None, really.

Other Thoughts: So 2 things. If you plan to have any kind of LED colored fans in your case you are going to need to replace all the fans with colored ones if you want to fill your case. I have two 140 mm red corsair fans on the top of my case and its not that bright. I'm going to replace the front 2 with red fans as well to saturate the case with color. Also the middle point where you screw in the motherboard standoffs was installed in a weird way, where as a peg was sticking out, so i couldn't put a screw in through the mother board. I also couldn't remove it, so my MoBo is installed with only 8 screws. Weird.

4 out of 5 eggsGood Enthusiast Case

Pros: Well built, good ergonomics, included fans are above average for what you'd expect in a case at this price point. Tool-less drive mounting is well implemented, large graphics cards fit nicely, roomy case.

Cons: No fan controller. It would be nice to have a fan controller included that would interface with Corsair Link.

The space between the motherboard tray and the right side panel needs to be at least an inch wider. At least, that's my opinion. If you aren't really talented at wire routing, you may find there isn't enough space between the motherboard tray and the right side panel. Built in cable tie downs (like those in the 900D) would be nice.

The exterior finish of the case is a finger print magnet.

Other Thoughts: Overall, a very good value for the price point.
