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.

4 out of 5 eggsGood Case

Pros: Good looking case, solid rigidity, black interior, good filters.

Cons: Front panel had broken off clip, piece missing from box so I couldn't even clue it on. Part of front panel debonded, which I will glue back together.

Other Thoughts: It would be nice for the thumb screws to be larger and have larger threads.

3 out of 5 eggsToo Big

Pros: Lots of room to work.
Ability to mount radiators.
The front panel is very attractive
Would make a great gaming machine

Cons: It's too long. Why have a mATX board in an 18" deep box?
Too wide. I don't need all the cable management

Other Thoughts: I wanted to upgrade a small office computer with a nicer case. I want small and quiet. This is not that case. My bad. This would be ideal for a cpu with integrated graphics Crossfired with a high end gaming video card. It is not the case for a small tower or desktop machine. I'm looking at the Silverstone

4 out of 5 eggsOne of the Few Nice Micro ATX Cases

Pros: Finally a decent case for a MATX board! I chose this over the Silverstone Temjin TJ08B-E and Precision PS07B-W, but mostly because of the sale price. Those look like great cases too, so the decision was not easy for once! I love the cable management, the rounded edges, the looks and smart design. I'm using this build as a combination desktop/HTPC, so looks and functionality are equally important. Corsair really nailed it with this case!

Cons: I think the plastic removable dual SSD cage was made with too brittle a plastic. I broke one of the two cages when I tried to take it apart, but it is no real big deal as I was only going to use one SSD anyway. This SSD cage is different than the one shown in the video. I think I would have liked that one better.

Other Thoughts: I removed the plastic 5.25 drive bay clips, because I'd rather use screws for my VFD and Blu-Ray drives that I'm installing. Since the FVD is using the top drive bay, I believe I could actually fit a full size radiator if I really wanted to go that route.

5 out of 5 eggsGreat little case

Pros: Great quality, good strength, mostly metal. Great price for a great buy. It fits all sizes of graphics cards, cable management, everything.

Cons: Not really a con (It's a small case) but it's kind of difficult to get water cooling in to it. Not so much a con, just a slightly annoying little thing.

Other Thoughts: If you are looking for a good looking MicroATX case, this is it. You cannot get one with the same quality for this price.

3 out of 5 eggsCorsair Obsidian Series 350D

Pros: Very attractive. Easy access to front fans. Plenty of room for micro-atx motherboards.

Cons: Front cover latches (push to unlatch/push to latch) are very cheaply made. On side will not now latch after only a week of use. Rear exhaust fan mounted directly to case rather than with vibration insulating rubber mounts.

Other Thoughts: I really wanted to give this case five stars but every time I look at the broken front cover I can't justify giving it five stars. There's plenty of room inside, it's an attractive case but those little things really nag.

4 out of 5 eggs

Pros: Very solid case with great options for cabling. Fairly spacious. Fits large video cards (GTX780 in my case). Looks fantastic. Higher quaility finish compared to the Carbide series. Not overly heavy. Price.

Cons: Big for a mATX case. It's exactly the same height as my Corsair Carbide 200R ATX case. I'd prefer it be a few inches shorter.

Other Thoughts: Buying again, I would have done a little more research as to the size as it defeats the purpose of going mATX if you have such a large case. But it's still an excellent case nonetheless.

5 out of 5 eggsGorgeous

Pros: Small. Gorgeous. Good build. Back channel to hide cables.

I wanted a simple, elegant, functional, black computer case, and not a terrible bad transformer looking teenager case. This is that case.

Cons: Almost a bit too small for my decent graphics card plus self contained water cooler.

5 out of 5 eggsCorsair 350D

Pros: Great build quality. Love the front panel makes it super easy to clean the screen. Nice clean design, lights on the power button are tasteful and not blinding.
Have it under my TV and it looks like it belongs there. Very attractive minimalist design. Aluminium front.
Running an AMD 8320 with a Corsair 100i cooler and its nice and quiet.
Plenty of room for just about any GPU, fits a 780ti with plenty of room to spare.
Great cable management and hiding places for a micro atx case.

Cons: Doesn't make me dinner or change the kids diapers... but thats what women are for.

4 out of 5 eggsCool case

Pros: - Very organized case. It has nice rubber grommets in the holes to route your cables through. All cables can be routed behind the motherboard tray, then brought through where needed for an extremely clean looking installation.
- All drive bays use trays or just slide your drive into them.
- Drive trays use pins instead of screws for easy tool-less drive changes.
- Includes 2 bays for 2.5" SSD's.
- Front uses a fine mesh screen for a dust filter that is easily cleaned.
- Awesome ventilation. Fans front and rear, second fan mount up front to cool the drives, and 2 more mounts on top for top exhaust ventilation.
- Plenty of room for large, full length video cards. Nothing obstructing them.
- Included front fan lines-up with the video cards to help keep them cool.

Cons: - Cover for the dust filter uses push to latch/release catches that are located at the top of the front panel. Just bump it and the panel wants to unlatch and fall off. Easily happens when you have to reach under your desk to push the eject button on your optical drive.
- 3.5" drive mounting inserts from the left side of the case, but puts the cables on the right side. Nice to keep a super clean looking install, but a pain to have to take both panels off to change a drive.
- The included front fan does not blow on the drives. Either drop it down to the bottom mount or add a second front fan to cool drives.

Other Thoughts: This case is about one inch wider than most. For most installations, it will not matter, but if you have limited space, this case might be too big to fit.

I took one egg off for the problem with the front panel, and the included fan not lining-up with the drives. not big issues, but annoying none the less.

Overall this is really a great case.

5 out of 5 eggsFor the first time, I'm giddy about my case

Pros: I'm not the best when it comes to cable management; I start off with good intentions, but the execution always leaves a bit to be desired.

With this case, however, it's nearly impossible NOT to finish with a clean, beautiful setup.

- The tool-less bays work like a charm.
- The cable routing options are second to none.
- The front cover comes off in a cinch without worrying about attached wires.
- The dust filters on the front and bottom are a piece of cake to access and don't require any disassembly.
- The matte finish on the case is gorgeous and very professional looking. This sits in my home office (for gaming, too!) and is right at home with the rest of my ofice furniture.
- Great cooling and airflow
- Space for any GPU setup you can fathom
- Compatible with a full size PSU

Cons: This isn't really a con because you know it going into it, but this isn't the smallest mATX case out there. It's not a mid tower, but it's larger than most mini towers. If you have the space for it, the space and flexibility you get inside the case is 100% worth it.

Other Thoughts: eVGA 760 4GB fit easily. I can't think of a card that wouldn't fit in here.
