5 out of 5 eggsExcellent Case, Tons of Room

Pros: I really love this case. It's very easy to work in, love the cable management, love the design of the front bezel where it can allow the fans to get air but still look stylish

The top fan mounting space works great for the H110i liquid coolers.

It is very well built, well packaged, and came with everything I needed to get rolling.

The fans that come with the case are very quiet but seem to do the job cooling wise.

Cons: I can't think of anything I am unhappy about with this case.

Other Thoughts: I would highly recommend this case to anyone building a larger PC or gaming system.

This is my first experience with Corsair cases but I have used power supplies and memory from corsair for years. I am very happy with my purchase

3 out of 5 eggsStatic electricity is killing my computer?

Pros: - Sleek, stylish, minimalist design
- Customization of hdd, ssd and cd dive placement.
- Plenty of room for water cooling options
- Silent operation
- Big window
- Brushed aluminium front cover finish
- Magnetic air filter mesh
- Kensington lock
- Option to upgrade front panel to the Airflow Edition
- Robust rubber feet
- Spacious cable management

Cons: - Does not have self retaining thumbscrews for the side panels
- Brushed aluminium is sharp on the edges and you need to be careful not to cut yourself
- The side window isnt perfectly flush, it bulges out a little (almost like the case is bloated)
- Wiping down the plastic side window will cause static electricity to build up and shock your components causing the pc to suddenly shut off (very concerning)

Other Thoughts: Whenever I wipe down the side window panel with like a micro fiber cloth or paper towel, I guess static electricity builds up causing it to shock the pc components inside. This has resulted in sudden shut off of the computer or blue screens. I really hope Corsair addresses this issue and give us a solution to protect our components. If a solution is found I will update/re-evaluate my rating.

5 out of 5 eggsSleek, Sexy with room for stuffs...I like stuff

Pros: Pros: Minimalist, sleek design perfect for adults with actual taste not looking for the garish, toy like gaming case trends that seem to dominate most of the landscape these days
- Plenty of space for all your needs. No really. You could easily throw 2-3 200mm+ rads in here and not have issues. It would take a really crazy build( see my specs below) to need more, in which case (pun not intended) you'd prolly be looking at a more expensive case from a custom shop online
- Bottom mounted drive trays cans be removed to really open this baby up for good air flows or expanded space for radiators. I have dual 980ti's and with just the stock fans this allows for more then enough air flow to cool these beasts
- Speaking of fans...I cant speak for everyone else, but the ones in my case I was happy to find not only push pretty decently but they are very quiet. tbh Im not gonna replace them unless they go bad.
- Solid cable management plenty of room to tuck and or organize cables out of the way for either aesthetics or unimpeded air flow
- Solid sturdy construction on body tho I do have issues with some areas that I'll address in Cons
- Light weight for the size. When I open the box I initially though this would be a lot heavier then it was. Was pleasantly surprised in that respect. I've seen full towers that easily run into the 60 lbs+ and that can be problematic for certain desks or just ease of transport.

Cons: Cons:
- had to RMA. The case arrived in reasonable packaging and didn't look like it had been dropped kicked by the UPS guy but none the less was damaged / defective.
The power button on the top of the front panel after hooking it up would light up but would not actually turn the PC on/off. I thought at first maybe I had done some thing wrong on the install and had 3 of my more experienced builder friends take a look and they came to the same was broke/defective. C'est la vie.
In addition to that, the front panel (while nicely adorned in a brush metal facade) had issues. It basically sits on 2 tabs on the bottom then snaps into place via two male / female snap tabs/clips at the top.These are PLASTIC. And as I found out apparently none to durable. The top right corner just wouldn't snap lock leaving the panel sticking out from that corner down. Metal tabs/fittings or even some magnets here would prolly solve this issue. This isnt a $30 dollar budget case, lets leave the plastic pieces on "high traffic" areas on those cases.
- small gripe here: While perfectly reasonable as is, another 5 - 10 mm of space in the cable management area would go a long way to making it a little easier to clean things up. Don't get me wrong there is not a lack of room so much as a little more would add some icing to this cake. Just my opinion.
- side panel was "warped"...but "hey when aren't they warped".. am I right ? Not a big deal but I definitely wouldn't be opposed to some bracing to stiffen the window side panel so it wouldn't flex as much

Note: Im not deducting stars for the RMA aspect unless my replacement has the same issues which would indicate either a manufacturing/design or QC issue on part of Corsair.

Other Thoughts: Overall this case is a SOLID buy and would recommend to pretty much anyone. Just be mindful of the front panel connectors and be gentle with it.

4 out of 5 eggsGreat Case

Pros: - Huge side window
- fan mounting options
- Finish very sleek
- excellent cable management
- Dust filters (top, front, bottom - PSU only)
- removable hard drive cages

Cons: - do not like the hard drive cages/holders. Same ones on all corsair cases and they just feel cheap. Guess you have to save costs somewhere though and I don't mind that it's here
- PSU mounting was odd, put in an RM750 fan down and for some reason the holes didn't line up. We ended up just floating it which really isn't optimal. This is kind of an issue and was the reason I took off an egg. I searched online and others had the same issue (unless that was the way it was designed? lol)
- corsair really needs to get up to date with side panel attachment. I also have a 300r and it's just horrible having to line up the tracks to get the perfect close. Ends up being really annoying on the back side. Many manufacturers have gone to the partial hinge. They have great mechanisms on the 780t and 730t. Not saying they should be the same, but I think they can do better
- no 3X 140 on top
- no dust filter on bottom 120s (really sucks if you are running intake on a rad configuration) - can be fixed by purchasing after market magnetic filters

Other Thoughts: My cons are mostly small issues. The only real issue for the average builder will be the psu mounting and I'm not sure if that was exclusive to the RM series PSUs. I didn't try with any others, but I was kind of surprised that the fit wasn't perfect...considering they are both corsair products.

In terms of options you will get more from the Phanteks Enthoo luxe at pretty much the same price point. I actually was yet to find something the 750d could do that the luxe couldn't. But there is something about the look of this case... its really slick!

2 out of 5 eggsAnother product that could have been good, but they cut too many corners

Pros: solid build

Cons: Top bay can't be moved, it is riveted in to place, for no reason. Front area under top bay has no attachments for additional bays. The front openings are also slightly smaller than normal, so some 2 bay devices wont fit out of the front of the case without modding it.

The motherboard cables for the wrong panel aren't long enough. Even after cutting all of the ties (which eliminates all of the fancy wire routing), it is literally impossible to get the reset switch cable to reach the reset switch pins on a standard ATX motherboard. I guess the 1/4 of a penny they saved there is more important than making the case easy to use.

1 out of 5 eggsWorst thing I've ever bought

Pros: It looks cool

Cons: The screws they gave me don't tighten into the standoffs for the motherboard. None of them. Extremely frustrated and disappointed in my purchase. The case has 1 job, to hold my motherboard securely in place and this case is unable to do that. Thanks corsair.
