4 out of 5 eggsAs Advertised

Pros: Lots of space, drive bays plentiful & easy to access/install. Cable routing keeps things clean. Lots of room for fans. On/Off switch for fan LEDs a cute bonus. Good case overall.

Cons: The radiator assembly fit fine, but my motherboard has a power plug near the top which made the radiator install for CPU liquid cooler very tight. Drive bay inserts a little flimsy, but as long as the Case isn't used on a bumpy road, should be fine.

Other Thoughts: Definite upgrade from my old case - better cooling and much quieter. Case is rather big with the wide points in side panels, but no other way to manage the cables as easily.

3 out of 5 eggsGood luck trying to use the fan mounts

Pros: Plenty of space, plenty of airflow. It's mostly solidly built, though the hard drive holders are pretty flimsy.

Cons: Basically no documentation, not even on Corsair's web site. In order to power on the front two fans, you have to plug in a molex power connector that is connected to the front panel. That one molex connector powers exactly two out of the three case fans, and without being near or even obviously connected to either.

That's a strange thing to do, but perhaps justified for cable management reasons. But if you do something strange, you have to document it. And my real complaint here is the lack of documentation. I understand not wanting to print off and include a 20 page booklet in every box, but is it really so hard to put a .pdf on your web site?

The bigger problem is the fan mounts, where the holes for the screws are enormous--big enough to drop a pen or pencil through a screw hole and into the case. That would be fine if Corsair included screws with large heads that fit the holes, but they didn't. I got a Radeon R9 Fury X and needed to mount the radiator somewhere, but the screws that came with the video card had heads small enough to fall right through the screw holes on the case.

I was able to mount the radiator using some thumbscrews that I had left over from my previous build using an Antec case. But there's no excuse for a case to have fan mounts that require unusual screws without providing said screws. One of the reasons you pay $100 for a case is so that you don't have to fuss with the company cutting corners to save a dime here and a nickel there.

Other Thoughts: Corsair seems to have a nice reputation on cases. This was my first Corsair case and will probably be my last. The fan mounts problem is ridiculous; I haven't had any such issues with Antec or Cooler Master in the past.

3 out of 5 eggsBright LED and Firewire? Nice layout

Pros: Great Layout
easy cable management
dual front intake fans

Cons: Super bright front power and activity LED! Can't leave the computer on at night in the room because it lights up the whole room. Can't put it to sleep because it blinks all night.
Why is there still a firewire port on the front of the case? The board that NEWEGG bundled with the case does NOT have a firewire header on it!!!! I would have rather seen an SD card reader or something more modern.

Other Thoughts: I'm currently trying to find a why to either darken the LED's or I might have to just disconnect them entirely. It's REALLY annoying. I'm not even sure what to do about the unconnectable and useless firewire port on the front of the case.

4 out of 5 eggsAlmost perfect

Pros: Great quality and finish.
No sharp edges. Good cable management options - which you will need.

Cons: Larger than what I expected.
Cable management for hard drives was a bit daunting.

Other Thoughts: The SSD/HDD trays are a bid counter-intuitive and you will end up running the SATA power and data cables in ways that you would not have imagined.
Whoever designed the SATA power connectors should be lynched (separate issue I know).
Unfortunately, Corsair leaves you to your puzzle solution skills in order to figure out how to mount SSD drives (yes, it CAN be done without adapters...) and how you should/could run the SATA cables and power. Luckily, the case has bulged sides which work to your advantage.
Tall case. My PSU's ATX power cable is rather short but it could make it to the top of the motherboard. Not 'tight' but just barely.
Plenty of room to fit the Asus GTX 980Ti STRIX video card...or two or three...or whatever your build might need.
I give this case 4 eggs because of the funkiness. Its a good case overall.

5 out of 5 eggsA+

Pros: Solid, sturdy, well built. Plenty of room for cable management all around. Properly ventilated with 2 front fans blowing air directly on the drives and one exhaust fan in the back, they're almost noiseless. The whole front of the case is a metal mesh, so is 3/4 of the top and 1/2 of the bottom for the psu, which has a slide-out dust filter.

Cons: None

4 out of 5 eggsPower supply fit

Pros: This thing is huge inside. Last build was using an AOpen HX-08.

Cons: So far this is a nit pick.. When you use a power supply BY Corsair IN a Corsair case it should just fit. No fiddling, no missed screws where only 3 out of 4 go into their proper holes. I had to screw the 4th into the supply and use the edge of the head to snag against the edge of the opening in the case. You should be able to put it where it goes regardless if you want the fan to pull from the case air then out or draw from the bottom. Rounding the corners of the supply doesn't do me any favors. My last Corsair fit into my AOpen case with -zero- fuss. No missed holes and it was another of their 750 watt supplies. RM750I used in this. Previous was a TX750.

Other Thoughts: Like the case, found the power supply fit to be odd.

5 out of 5 eggsNice and roomy tower

Pros: Plenty of space and 3 fans are pre-installed!

Cons: Fans seem to be weak, but not seeing any issues so far.

Other Thoughts: If using with MSI Gamer5 MB, the USB port is difficult to plug in --- BE CAREFUL or else you'll bend the pins on the port. Suggest to loosen the MB screws, connect USB cable to MB, then re-secure MB screws!

3 out of 5 eggsDecent case, a few issues.

Pros: Alot of room. Good design with management in mind. Alot of routing openings, and alot of room behind the MB panel for a ton of wires, and access to the back of the CPU is a REALLY nice feature.
Solid, sturdy, A TON of air movement room for us FAN guys. This thing can hold almost TOO many fans.

Cons: Could use more detailed instructions for the novice builder. Basically no instructions detailing MB installation, and front panel plugs.
Most experienced builders know that there is no wrong way to plug in the PWR and RESET pins, but new builders will not know this and worry about polarity. They could make this a GREAT case if it was "idiot" proof with more instructions then less.
My case had a wire caught between the front panel where it mounts to the chassis, completely crushing the wire which powered the fans along with there LEDs. Mine dont work.
HDD bay holders are flimsy plastic as opposed to the ones in most cases which are much more rigid.They work, again for experienced builders, not an issue, but for a novice, plugging in the SATA and POWER leads to the HDD's requires you to have to hold them or the HDD bay holder will just pop out of the bay.
This case almost TOO much open space, MANY opening for fans so if your NOT utilizing them all, you have open, vents, which is not a bad thing, but should be filtered.
Thumb screws that hold the side panels are not great, and if not careful, will strip easily.

Other Thoughts: Despite the cons, this is a really good case.
Lots of room, and well designed for wire management, ( lots of routing holes ) and the access in the side panel to the back of the MB to get to the back of the CPU in case you want to change coolers is awesome, and something every case maker should be doing. No need to remove the MB just to upgrade a cooler.
My install was easy with alot of room and options. I AM VERY disappointed that the wire was crushed in the assembly of the case, I now have to disassemble the entire build, if I want to send it back, OR, cut and splice the front fans to a connector in order to hook them up. I havent even checked yet to see if the front 3.0 USB plugs work or not due to the wire being crushed. Took 2 eggs off what otherwise could have been a 5 egg case.

3 out of 5 eggsGood case with a few complaints

Pros: Fairly inexpensive for what you are getting. Looks good. Mostly easy to install equipment into it.

Cons: The bays for the hard drives are a bit cheap. The plastic is quite flimsy. Also, I couldn't use the 3.5" adapter I have my SSDs installed in. Well, I did, but the holes don't line up to let it click into place in the bay.

The screws used to hold the side panels are a little bit of a pain. They are designed to unscrew from the case but not come out of the side panel, however I find it's challenging to get the screws threaded back into the case again...shouldn't be that hard to engineer this not to do that.

The other issue which I wish I'd noticed before now is that the headphone jack on the front of the case doesn't work correctly. All sound is send out only the left channel. Now that I got everything installed and working, I'd hate to have to take it apart to return I'm not sure how I'm going to work around this problem (Corsair reps, any suggestions?)
