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?)

5 out of 5 eggsThis thing is awesome

Pros: Large, very well thought out and easy to setup. This thing has everything where you need it and is well put together. Seems very sturdy also. Plenty of room when putting a new system together. Buy it!

Cons: none

Other Thoughts: It comes with everything you would need for any combination of drives, cards and mobo. A bunch of tie wraps, a bunch of various screws and elevated screws, etc.

I also like the fact you can turn off the LED fan lights with the push of a button on the front panel: very convenient.

4 out of 5 eggs

Pros: Room to breathe. Enough space to install components with ease. Layout is good and very good airflow.
Again Good Value.

Cons: I really have not found the Side panel fan mounts useful at all and i would have liked a regular panel.
Important! A nut or piece of metal or weld is in the way when removing anything in PCIe_16x slot one. Very difficult to remove graphics cards. (asus p8z77 v pro)

Other Thoughts: In as few words as possible , the 400R is a value oriented Mid-ATX tower with the added touch that Corsair implements in all their premium What is to be said that has not already. Very nice case , decent price.
PC cases. When comparing other Cases of this price range it is hard to find many contenders.
Just fix that silly weld job.

4 out of 5 eggsGreat overall

Pros: Great wire management, everything feels sturdy. The rubber around the wire management holes feels nice and supple to the touch (I was worried it would be stiff and plastic-like). Thumb screws abound which is a nice thought. My first bottom-mounted PSU and I'm a fan already. Makes the case just feel neater to me for some reason. Water-cooling reservoir ready (though I haven't bought one yet). Case fans are sufficiently quiet.

Cons: Thumb screws are a nice after thought but they all feel like they don't thread correctly... I end up having to get a screw driver anyways because they don't want to thread without the extra torque.

Also, I didn't detect any sharp edges but I had a bloody knuckle within 5 minutes of working on it... no idea where I got it.

Other Thoughts: Great case overall, would recommend.

4 out of 5 eggsGreat wire management - Roomy - Bad front audio ports

Pros: I was torn between getting this and a Cooler Master HAF - I went with this one because of the rubber grommets around the cable routing holes.

This case has plenty of space without being excessively large. The rear panel (Behind the motherboard) features a kind of geometric bulge which makes the case about 1.5" wider, which gives your cables plenty of room to reside without pressing against the panel and bowing out the side. The overall effect looks good and provided ample space for my setup without greatly expanding the overall size of the case. A parallel bulge on the front panel gives plenty of room for your cooling solutions (Air in my case, though it looks quite accommodating to a water-cooled rig)

The construction is quite solid - all the main body panels are metal and the structure of the chassis is solid. The only plastic parts are on the front face, though the color between the metal and plastic is similar enough that the aesthetic is maintained.

The light button on the front panel works as advertised. With the lights off, the front panels merge perfectly with the CD-drive covers, so that this case wouldn't look out-of-place on the desk of any businessman, but tap that button and its suddenly a LAN-box showcase. Speaking of, the top panel features a deep carrying handle which should make transporting this box a breeze.

As far as noise is concerned, it's not quite 'so quiet I forget it's on,' but it's pretty dang quiet.

Cons: The only real problem I've experienced so far is that the front audio jacks appear to be DOA. I'm getting in contact with Corsair to see if they can resolve this, and will update my review with their results.

Other Thoughts: The little rubber feet on the bottom are great - they stick to my desk surface like glue. In fact, while I was building the box, one of the feet peeled off the case while I was trying to rotate it on my workbench. The feet themselves are wonderful, but perhaps another strip of glue attaching them to the case might be called for.

My build contains:
Asus Z97-A mobo
Intel i5-4690K CPU
nVidia 670 GTX GPU
2X8GB memory
256 GB Sony SSD

2 out of 5 eggsTight when using liquid cooler

Pros: Nice design and quiet fans.

Cons: My setup used a ASRock X99 Extreme4 with a Corsair H100i CPU cooler. When mounting the cooler on the top it hits the heatsink on the MOBO and makes it tight to connect the 8 pin ATX 12V connector. I had to remove the cooler to connect it.

Other Thoughts: You can mount the cooler on the side panel but that would be a PITA getting in the case. They need to redesign the case giving more room between the top and MOBO location

5 out of 5 eggsAwesome Case!!!

Pros: The case is way roomie, and has tons of ways for running your cable to hide them and make getting to your motherboard when you need to easy. VERY Quiet! I have owned this case for over 3 years now, and I still love it! Well worth the price tag!

Cons: None what-so-ever!

Other Thoughts: I recently had my front USB ports malfunction (12/2014), and when I tried to order the replacement front I/O panel the manufacturer (Corsair) was out of stock. I had to wait 2 months for it to become available, but Corsair made it right and shipped me the replacement part for free!

I would recommend any Corsair product to anyone, anytime! You cannot go wrong when buying from this company.

5 out of 5 eggs

Pros: Case has lots of room and great cable management!!!! It has plenty of extra fan mounds!!! I am running 8 total fans. The 3 that came in the case, (2) 140 mm for the side panel and (1) 120 mm for the bottom of the case and 240 mm corsair H100i water cooler which mounts on the top of the case. Room is not a problem.

Cons: If you install a water cooler in this case be aware it does get tight between the fans for the water cooler and the top connections for you motherboard! You can still get to them but it is very very tight and I could not use the mount holes for the water cooler. Its not a hard adjustment but I had to in order to connect the power and fan to the top of the motherboard.

Other Thoughts: With the water cooler problem I had, it still would not stop me from purchasing this case. With the room and cable management in this case, It is still worth the purchase!!!

5 out of 5 eggsSturdy Case with Decent Cable Managing

Pros: Bought this case to replace my Antec Three Hundred I have been using for the past 5 years, and I normally enjoy basic sturdy designs so when I was looking at Corsair cases at my local store, I though they seemed well built and durable. So I came onto Newegg to get a better selection of computer cases and saw the Carbide 400R which had various areas which fans could be mounted, along with cable management that you have access to on the right side panel. It comes with two white 120 mm fans which you have control of whether or not their white leds are on or off by a button on the cases front panel.

This case is also pretty good if you are planning to add a closed loop water cooling for your processor. I ended up getting a Corsair H100i water cooling setup, and installed into the case without any issues of space or location available. I currently have my radiator mounted at the top of the case, and my cpu idles anywhere between 20-26*C, when gaming or actively using different applications on the computer it will go up to 30-40*C.
I also had no issue getting a Geforce 770 GTX to fit inside the case and was able to connect both power cables necessary for the Video card without any space issue.

I would recommend this case to anyone who is looking for a good mid-range computer case, and not looking to spend over $100.

Cons: Only issues I have with the case is, it is a little heavy, and probably would be troublesome to move constantly if planning to use for traveling to LAN parties, friends houses, or gaming conventions. Beyond that I have no actual issues with this product, and hope to continue to use for 5+ years.
