Small in size but big in capability, the Corsair Obsidian 350D case is designed to build a high performance system in a Micro ATX form factor. Oriented for Micro ATX and Mini ITX platforms, the Obsidian 350D's ample interior accommodates dual ODDs, dual hard drives, dual SSDs, dual full-length graphics cards, and a water cooling radiator. Cable management, and tool-free access and drive installation, make the build a more enjoyable experience. Complete with clean design aesthetics accented by a brushed aluminum front panel, the Corsair Obsidian 350D is a great look for any room, whether it is on or off!

  • newegg Compact Size The 350D is smaller than mid-tower cases, so it’s at home on a desktop or tucked away out of sight. The smaller dimensions make it great for building systems for traveling, too.
  • newegg Superior Expandability With the 350D, Micro ATX cases are no longer just for building basic systems. There’s room for a full-size liquid CPU cooler and two dual-length radiators, while the five PCI-E slots allow you to install dual full-length graphics cards without using up all your slots. And with two 3.5-inch hard drive bays, and two dedicated 2.5-inch bays for solid-state drives, storage expansion isn’t a problem.
  • newegg Flexible Cooling Options The 350D comes with a 140mm intake fan and a 120mm exhaust fan, and there are mounts for five total. The front and top mounts are spaced for 240mm radiators for more cooling options.
  • newegg Fast, Neat, and Smart The 350D is designed for fast and neat builds, with features like tool-free access and drive installation, and an innovative cable routing system.
  • newegg Convenient I/O Panel A front panel USB 3.0 connector and audio I/O make 350D-based systems easy to use.

5 out of 5 eggsGreat case for a micro ATX

Pros: Tons of spots to mount fans
Grommets on every cable mounting hole
Removable HDD & SSD cages (Removed mine for airflow)
Comes with a front and PSU filter
Grommets for anti-vibration on the top fan mounts
The case supports a decent sized air cooler as well

Cons: The 5.25 bays don't look very good once you put something in them, as you have to remove the covers to use them
Doesn't come with a top filter
No grommets for the fan mounts besides the top

Other Thoughts: Wasn't too hard to work in, considering my hand size (I'm 6'2")
I bought a top filter from Corsair's website pretty cheap. It's not bad, but it's just a mesh instead of something like the front filter.

3 out of 5 eggsnever again

Pros: Good for wire routing, roomy inside

Cons: made cheap, poor customer service, big

Other Thoughts: The front cover has 2 small pegs holding it on to the case. the cover is metal plated and has some weight to it. I received the case with one of those pegs broken. I put in an RMA with corsair. I received an approval from corsair to have an replacement part ship to me. Well that was the last thing I heard from them. Now, it has been a week, and no shipping notice. I assume that I probably won't be seeing an replacement, if it is taking this long. This is also a big case for being considered a micro case. Its, wide, making it easy to route wires.

4 out of 5 eggsExcellent case for the money

Pros: Lots of room to work with. Cable management is a breeze. Dust filters easy to remove and clean. Stock fans silent and move plenty of air. Overall very satisfied with the case - see cons.

Cons: The only reason why I docked one egg is because the clips that hold the front panel in place were broken. Not a super big deal as the panel still stayed in place while in normal upright position. Just a minor gripe, but I would def. go with this case again.

Other Thoughts: Not sure if the clips being broken were due to shipping or just flimsy construction. I am very satisfied overall and would go with this case again for any future builds.

4 out of 5 eggsCorsair 350d case

Pros: Plenty of room to work with. Good cable management. Looks good as a stock unit before drives are added. Plenty of dust filters, though it would be nice to have one on the top of the unit. Still a good price even though Corsair "dropped the ball in many areas"

Cons: There are a lot of issues with this case. It seems like their design team was going somewhere good with the 350d, but somewhere along the line really dropped the ball.

Overall everything about the case says "I'm a cheap case" with lots of injection molding.

The biggest thing that I really really really "dislike" about the case is; the drive bay faces are oversized. When you puts something in the drive bays you are left with an unfinished face, because the sides are unfinished and it creates a hideous relief. Corsair's management really dropped the ball by not creating different faceplates for different drive options to sell as an after-market upgrade part. STUPID!

Although the 2.5" drive bays worked out good in my build they are what they are. Don't waste your time trying to modify or reconfigure them because you with probably just end up breaking them, due to the fact that they are cheap injection molded design.

Top fans (if used)- the top fans have the potential to pull in so much air, so why don't my case manufacturers put dust filters on those as well as the face which has more static pressure issues. - Once again- at least make one as an aftermarket upgrade item.

My I/O shield didn't line up good. I pulled my mother board back out and rechecked the installation and it just doesn't quite line up right (could be the motherboard, but that's doubtful, because all of the parts on the I/O are off by the same distance).

The usb3.0 ports are incredibly tight- almost too tight; hopefully they will "break in" before the just plain "break"

Other Thoughts: Overall for the $99.00 that i spent on the case it is probably worth it; especially if you don't plan on putting anything in the drive bays. I just can't get past the fact that they do no sell brushed face-shields and Corsair is just happy with the ugly unfinished reveal that is left on both sides of the drive bays. Once again, that is the HUGEST mistake I have ever seen made on any PC case. If it weren't for the STUPID 5.25 drive bays being so lame, I would love this case, but now it's just another cheap case that I am looking to replace in the future and as far as I am concerned $99.00 wasted buying the case and 8-hours of my time wasted doing heavy modifications to make it look good with my slot-load drive. TAINTED

I now look at brands like Corsair and Silverstone as just another brand that is too cheap for me to even waste my time building with. They both have really gone down hill as far as quality and end-use engineering. They spend so much time engineering the ease-of-manufacturing, that they really drop the ball on end-use-design.

5 out of 5 eggsExcellent Case

Pros: -Easy to build in
-Room for full length graphics cards
-Good build quality, fit and finish

Cons: None whatsoever, and to people who said that the case is too big for mATX, There's something called the specifications page with the dimensions posted. Grab a darn tape measure and see if it's too big. Seriously, half of the gripes of this case are size related by the other reviewers and it is obvious that none of those people have research skills.

Other Thoughts: Here's the list for my build.
-Corsair 350D mATX case
-Asus Maximus 6 Gene Motherboard
-Intel 3770K Haswell processor
-EVGA GeForce GTX 780 ACX (X2)
-Corsair AX860i power supply
-Corsair H100i CPU cooler
-WD Black 1TB HDD
-Intel 120GB SSD
-Corsair Vengeance 16GB RAM

1 out of 5 eggsBuy the NZXT S340.

Pros: Looks great, features are up to date. Seemed like a great buy for $70.

Cons: Nothing innovative, large for a mATX case (larger than mid-Tower NZXT s340 which i strongly recommend over this case)

Everything pretty much broke. First it arrived with a large nick in the front bezel, aluminium shows through. Second, the 120mm fan ticks.

Things that broke during normal use- when I plugged in the USB 3.0 header, I noticed it required a great deal more pressure than my old case. I carefully unplugged it to re-route the cable, and it broke off the plastic part of the header on my mobo. Ah no big deal, its just plastic, right? Wrong. Turns out it broke that header and both my USB 2.0 headers as my front usb no longer works in this case, my old case, or with the replacement I/O corsair sent me.

The ssd cage is also terrible designed. The cages are attached in 6 places to each other, so unless you have 6 hands, good luck getting them apart without breaking them (which I did with minimal pressure).

And lastly, the most annoying thing ever. There are no rubber pads for hard drives, so whenever mine turns on, the ENTIRE CASE HUMS VERY LOUDLY! I measured the volume with an iPhone decibel reader and found it was 60 decibels from where I sit, compared to the 43 it usually is. For those of you who are unfamiliar with the decibel system, that is ~13x louder.

Other Thoughts: I thought Corsair was known for quality control and good customer service, but customer service sent me a new I/O (which fixed nothing) and told me tough luck with the motherboard. Ouch.

Please, just buy the NZXT s340. I built a PC for my friend with it and it was flawless. Same price, smaller even though it's a mid tower.

5 out of 5 eggsCorsair Obsidian 350D

Pros: Beautiful looking case. Plenty, PLENTY of room for routing cables and making everything inside look super neat.

Cons: No external 3.5" bays for memory card readers, but I knew this going in.

Other Thoughts: Built this for a customer, so I have no opinions on actually using it, but I was jealous.

3 out of 5 eggsNice case, but minor flaw

Pros: The case is very sleek and nice looking. The cable management (routing behind the panel the system board sits on) does a decent job of keeping things tidy inside.

Cons: After 4 months, the audio jack in the front panel has started to fail. When I have my headphones plugged in the sound will randomly cut between headphones and speakers. I installed the latest Realtek audio driver suite for the motherboard. While that didn't fix the problem, it confirmed the issue for me by notifying me every time I supposedly unplugged and replugged the headphones. It occurs even when the headphones are sitting on top of the PC and no cords are being jostled, and occurs with multiple headphones/earbuds.

Manufacturer Response:

Dear Customer,

We're sorry to hear that the audio jacks in the front I/O panel is causing you troubles. If you would like a replacement front I/O panel, feel free to contact us by submitting a ticket at or calling us directly at 888-222-4346 and we'll be more than happy to assist you.

Thank you,
Corsair Customer Support

4 out of 5 eggs

Pros: It's a very nice case that made it easy to build my PC without too much trouble, especially for cable management.

Cons: The front cover that covers the front USB/audio inputs and the power button has flimsy latches to lock it into place, so one of them broke off when I put the DVD drive into my PC. I didn't notice this right away, so I thought I had messed up the build when the power button didn't work. It was just that latch being broken so that it didn't sit right in there. Tried to RMA this issue to hopefully get a new cover, but their website refuses to progress past the first step to submit a ticket.
