3 out of 5 eggsNew build

Pros: Pro case was cost effective has a lot of fan slots good space fit my 980 gtx ti with no issues. Over all decent case

Cons: I bought an msn gamer 7 atx board and the corsair hi100 gtx liquid cooling. The cases mounting brackets and board combo made it to where I had to create new screw holes on the mesh top to secure the liquid cooling radiator. Also while the liquid cooling radiator is in you have have an extremly thin profile fan to get the rear mount fan in. So with this case it is not liquid cool frienldy.

4 out of 5 eggsSo So.

Pros: 1) good sized mid-tower case.
2) well fitted with other Corsair products--power supplies, liquid coolers, etc.
3) well organized front panel (some people might not like it)
4) many hdd bays as well as optical drives.
5) customizable space for case fans.
6) Easily marked for power, reset switch cables.

Cons: 1. Only 2 case fans are attached. Front, and back.

2. HDD bays are a nightmare. I thought that those bays with trays are so coooool. However, once it fitted, it won't be able to remove those hdd from trays before you eventually break them. To remove trays from hdd bays, need to squeeze the two-end parts of the tray. However, it won't get squeezed once a hdd is on the tray. So now I understand why Corsair sells those trays from their website. Maybe I don't know how to do it, so I tried to find about removing hdd from bays, I couldn't find any information.

3. Side panel is kind of weak. It is not easy to install case fans because screws might ruin the side panel.

Other Thoughts: Well it is definitely not a best idea to purchase this case in the end of 2015.

5 out of 5 eggsLoads of awesomeness

Pros: This thing is great quality, no joke, it's formidable and sleek etc. But don't let the pic fool you into thinking this is a small Mid Tower Case, it's gigantic! There is a back panel for hiding cables that is removable and plenty of space for all your parts inside. It's sexy too.

Cons: A bit hard to remove the fans in the front, but otherwise nothing to note.

Other Thoughts: Worth all the money

4 out of 5 eggsWorth $50. shipped not $80.!!

Pros: Title says it all. Got this case from NE with a $10. off code and $20. rebate shipped free.
What's to say. Nothing special about this case but very functional.
Screw less snap in 5.25" bays
Screw less removable 3.5" racks with screw holes for 2.5" drives
Cut out for installing CPU cooler.
Cable cutouts
Top front 2-USB 3.0, audio connectors, power and reset buttons
Can install up to 7 120/140mm case fans,
Comes with 120mm back exhaust and 140mm front intake 3 pin MB connector fans.
Thumb screw attached side panels and expansion card back plates.
PS and front fan filters
Adequate supply of screws and some zip ties
Wide enough for a CM Hyper 212 EVO
Black painted interior
Rubber bottom feet

Cons: This is a mid price case so Corsair cut some corners.
No rubber grommets on the cable routing holes. If you want them get the Corsair 350D Grommet Kit
The manual only states the case features. Useless for first time builders.
I had to cut the zip tie on the audio cable to get to reach my MB pins, needs to be longer.
No fan filters for the top or side fans. I purchased a Silverstone Tek 140mm x 2 Fan Filter with Magnet, Black (FF142B) for the top grill. Fits perfectly.
The whole front panel has to be removed to clean the front filter. Grab it from the bottom and pull outward. I would not bend back the metal tabs to remove the filter. The tabs are part of the front metal grill.
The power led is a bit bright. No big deal for me since my case sits low.
Top fan grill is a bit flimsy. I would not store anything on it.

5 out of 5 eggsgood for the money

Pros: good space. can fit most parts.

Cons: like others have stated.... if using 140mm fans on top.... the optical drive might have to be moved down a slot.... 120mm fans work fine though.
larger gpu's like a 980ti can block one of the side fan mounts with its power cables. the other one is fine though.

one of the front panel usb ports was defective. im not removing an egg though because corsair has a really convient process where you file a request and they send the part to replace it. so instead of taking it all apart and replacing the case... i just swapped front panels. they also didnt request that i send the old panel back. the new part arrived in one day after requesting it. really fast.

my biggest creivience with the case is the type of screw and washer that they used to secure the front panel . really inconvient to take them out and harder to put back and screw in correctly.

4 out of 5 eggsGreat case

Pros: A lot of space, plenty of air flow. Ability to add many more fans. Being able to hide the wires behind the case.

Cons: Arrived with one fan not working.

Other Thoughts: Great case. I love that when I build my next computer I can expand this case to handle much more performance. Only issue I had was the front 140mm fan did not work. But Cosair RMA process was a breeze. Just logged it on the website it was approved in a few hours and shipped a day later. They didn't even make me send the old fan back. New fan works perfectly.

1 out of 5 eggsTrash

Pros: Big Case.

Cons: Although big, I could not fit this within the case: seidon 120v push pull setup.
4 Out of 5 of the Drive bay clips broke within a year and would not stay in place anymore.
The case scratches very easily.
Some of the case fan wires were bad on arrival- 3 of my fans in the case aren't spinning that did in my old build.

Other Thoughts: Very Trashy computer case not worth the money. If I HAD to buy this case, I would say this case is worth $40 tops.

4 out of 5 eggsLooks good, needs some fixing though.

Pros: This is one clean case. It looks great and definitely holds parts... for the most part.

Cons: I have a smaller factored ATX motherboard. Z97 anniversary. With this motherboard and case combo, the outcome isn't the best. I couldn't fit my Corsair H75 inside, it was too cramped inside because the CPU socket is set too far left. I couldn't even fit it with one radiator fan. It sucked. RMA'd that beast. The CPU back plate cut out in this motherboard needs to be bigger in order to compensate for smaller motherboards... Was planning on overclocking but that has been set back.

Other Thoughts: Do your research (should have done that on my part) and this case will be good. With a full sized ATX motherboard, you shouldn't have that problem at all.

2 out of 5 eggsCase is good but beware the rebate

Pros: Good case, solid build. Would be 5 stars if not for their failure on the rebate.

Cons: Rebate would not work. Kept saying that it was not valid for this country. Double and triple checked my entries but it would not go through.

Other Thoughts: If you are going to advertise and sell a product claiming a rebate make sure it will actually work.

3 out of 5 eggsSlight problem, otherwise a good case

Pros: The case looks nice and has two great dust filters. The included fans have been reliable so far and I can't complain about the internal layout, which is spacious and easy to work with.

Cons: I purchased some AeroCool Shark 140mm red LED fans for this case, and soon after installation I noticed a scraping sound. It turns out that the fans were scraping against the intake filter.

I 'fixed' this problem by using a few pennies as shims to keep the front filter away from the fans. I really wish the design engineers had given 2mm more space to the fans. I admit to being disappointed with Corsair.

Other Thoughts: Why is this a problem in a modern computer case? Good grief.
