5 out of 5 eggsAn Absolute Joy

Pros: Great design and airflow. Looks great on a desk or tucked away.

Cons: Corsair doesn't give me any kickbacks for recommending their products.

Other Thoughts: I won't use any other case from now on except corsair. I just built an HTPC for my mom and used the 250D and it met all expectations. I currently have a 600T as my gaming rig and when I built a PC for a buddy of mine, I talked him into the 500R and we were both very happy with the results. Also use corsair PSUs with great satisfaction.

5 out of 5 eggsSmart case

Pros: Very smart design.
Excellent airflow plans
Looks fantastic.

Cons: Needs both fans to be operating for proper airflow - See other thoughts.
The power supply bracket could be a little more sturdy.

Other Thoughts: I didn't expect to like this case as much as I do. I bought it merely to match my Corsair 350D case to my guest computer.
The amount of thought that went into where things are placed and how is obvious.
The sides and top all come off for working with, so it ends up being even easier to fiddle with the motherboard when it's in there compared to larger cases.
The airflow system is excellent IF you use both fans. I'm currently using an ASrock H97 board in this that only has 1 case fan plug.
I did a smoke test to see where the air was flowing, and the front fan seems to be mixing air about the front of the case and out the sides, but doesn't push it over the motherboard. The 140MM fan just isn't going to push enough air through the case.
This isn't a very big deal, as I think most motherboards have more than 1 case fan plugs. If not order a good splitter, or if your PSU has molex, a molex to 3 or 4 pin fan plug.
The case comes with a 120mm on the side too, and once they're both running air will be pulled over the motherboard.
Conversely you can run the 120MM to pull air in since the side vents are filtered. I'll smoke test them in both configurations to see which is ideal for airflow/dust prevention.

All in all I'd rank this as the best case I've worked with. The top window lets you view your equipment at work, and doesn't show your wires if you've given a little effort to hide them. And it just looks great.

4 out of 5 eggsGreat case - Primary gaming PC fits great

Pros: This case has fit everything I've wanted to install pretty easily. Coming from a full tower, I was worried, but my entire gaming PC fits fine in this case. I was using a stock intel cooler, but recently upgraded to the H100i and it fit perfectly. There is hardly any space betweent he fans and the motherboard, but the fans don't touch anything and the cooler does its job great with the space it has.

The case has a ton of great airflow, and the air passively comes out of the back with ease

Cons: None other than the fact that the rubber feet on the bottom came off the first day I got it, so I had to tape them back on because otherwise the case was uneven. But it may be me, because every case I get loses case feet fast..but this is the only reason I took a star off.

Other Thoughts: PC specs (In the case)

Intel i7 4790K
ASUS Maximus Impact VII (M-ITX)
8GB DDR3 Corsair Vengeance RAM
MSI Nvidia GTX 680 Lightning (yes, it fits perfect and doesn't touch anything else)
Corsair h100i Water cooler
Samsung EVO 840 SSD
Western Digital 1tb mechanical drive
Coolermaster 850watt Silent Pro II

4 out of 5 eggsGood case

Pros: One of the only options for water cooling in the mini-ITX form factor. It can fit a slim (30mm or less) 240mm radiator and a 60mm thick 140mm radiator, which is really good for a mini-ITX. It can fit a full size PSU and GPU. Dust filters on all the fan mounts except the two 80mm ones, even the PSU has a dust filter. Pretty good build quality. Looks good. Everything is toolless. Hard drive/SSD bays, top and side panels, PSU, GPU, everything. The only thing I can remember needing a screwdriver for was removing the 5.25" bay.

Cons: Big for a mini-ITX. No filters on the 80mm fan slots. Only comes with one 120mm fan while the slot next to it is empty. I wish Corsair sold an optional windowed side panel for it like they do for some other cases. That would be great for showing off acrylic water blocks considering the horizontal motherboard and the GPU being next to the side panel. Cable management is as bad as you'd expect for a mini-ITX, although at least they tried to include places to use cable ties on.

Other Thoughts: One of the best mini-ITX cases on the market for high end rigs, although if you just want a HTPC or whatever you'll be disappointed with the size.

5 out of 5 eggsNo Compromise Mini ITX Case

Pros: - Very Spacious
- Has a great finish and will look great with almost any decor
- Has space for a optical drive
- Can switch the top and side panels in any way.

Cons: - A little expensive compared to other Mini ITX cases
- A little bigger than other Mini ITX cases

Other Thoughts: I call this a "no compromise case" because this case doesn't lack in many areas despite it's size. Usually Mini ITX cases do away with a lot of the features and space you would normally get in bigger housings for your components. This case can handle most larger gpu's (around 11 inches) and even has enough space for most dual radiator liquid coolers (such as the H100i). Also has plenty of space for cable management due to the position of the PSU to the motherboard. All in all despite it's roomy accommodations it will end up being a bit tight at the end of your build but that's to be expected. If you can shell out a little more for your case, I highly recommend the 250D. If you are looking for a cheaper solution I would take a look at Thermaltake's Core V1.

4 out of 5 eggsNice case!

Pros: A little bigger than the typical ITX case (see other thoughts), Big cooling fan. Quiet. Lots of space in front of the PSU.

Cons: The plastic holders for the hard drives are a little on the brittle side. One of the flexible curvy parts you grab to remove the drive snapped right off just getting it out empty. Still works ok but they seem overly cheap compared to the rest of the case.

Other Thoughts: I love the ITX form factor and build a lot of home and work stations. One downside is all the ITX cases are seemingly made to be as small as possible (rightly so) but this makes positioning them difficult at times. They are too small to go on the floor where they wobble around on carpet. Monitor cables are too short to reach ground level. Then if you want to use a USB drive or external DVD drive, you have to crawl on the ground to plug it in,
On the other hand they are pretty big to set on a desk and then you have to worry about heat and noise issues.
I used this case on my home system, swapping out a Lian Li that is a great case. This one was easier to install, especially the PSU since it sets below the motherboard with open space in front of it.
The size and dimensions are about perfect. It's got enough width so it's very stable and being slightly deeper and taller allows the cables to reach the rear ports and the front of the case is reachable to use DVD drive and USB ports.

5 out of 5 eggsCorsair Obsidian Series 250D

Pros: + Plenty of space
+ Easy to assemble
+ Built-in dust covers
+ Good air flow
+ USB 3.0 front panel connectors
+ High quality parts / didn't feel cheap

Cons: - HDD caddies were difficult to use / felt like I was going to break them
- No wire management
- Had to buy a 3-pin to molex fan connector

Other Thoughts: I was searching online for a case for an HTPC build that was stylish, had good air flow, easy to assemble, and expandable. After watching some videos on YouTube, I decided to go with this beautiful case. The case is a lot bulkier than usual, so it doesn't fit the bill for a traditional HTPC. It's wider than my micro ATX case. But I liked it for all of its other features.

The case comes with two fans, a 140mm fan in the front, and a 120mm fan on the side. You can install another 120mm fan or a radiator as needed. My motherboard only had a single connector for a fan besides the CPU fan, so I had to purchase a 3-pin to molex connector. I like that there are built-in dust covers on the front, on the side, and under the PSU. The case can support an ATX power supply, which is nice because it's easy to buy a replacement as needed. Next to the PSU slot are slots for 2x 2.5in HDDs and 2x 3.5in HDDs with built-in caddies. The caddies are tool-less, but were a pain to work with. I felt like I was going to break them by adding in an SSD. The front panel has 2 USB 3.0 connectors as well as connectors for audio in and audio out. The case has room for an optical drive if you need one. There's plenty of room inside the case so it's not cramped. However, the case is lacking in wire management. Overall, assembling the computer was easy with the thumbscrews in the back. The case looks great with the brushed metal front. It didn't feel cheap at all.

Parts for my build:
Corsair Obsidian 250D case
ASRock B85M-ITX LGA 1150 motherboard
Intel Core i3-4150 CPU
G.Skill 8GB (2x4GB) DDR3 1600 memory
Seasonic 400W fanless PSU
Crucial M500 240GB SSD

5 out of 5 eggsExcellent gaming case

Pros: Plenty of room for cable management, especially with the 3.5" drive bays removed. Great for performance rigs where you want plenty of room for radiators, full-sized VGAs and PSUs. Included dust filters are quality, and seem to really do their job, even a week or so in. Looks great and is even easier to put together.

Cons: LED pins felt a bit loose.

Other Thoughts: I found the backplate to the motherboard to be a tight fit, but I can't say that's the case's fault any more than the motherboard. Included case fans are decent, but not the best from Corsair that you'll find.

5 out of 5 eggsThis Takes the Mini out of Mini-ITX

Pros: Enough room to get your head inside the case after you complete the build, well, almost. After to working on M350 compact cases for years, it was a year luxury to have all the room inside this one.

Lots of air flow options, large front fan, large side fan, large side opening where the graphics card will go, two empty 80mm openings in the rear over the motherboard. There is enough air venting that low-RPM, low-noise fans can be used throughout.

The cables for the front panel include USB3, and a reset button. Both are a step up from the tiny cases.

Cons: Phillip mentioned he had trouble with the pins on the drive caddies. I found a way to install them that seems better than the manual. Remove two pins from one side of the caddy. This involves pressing the rubber mount so it falls into the interior of the caddy with the pins intact. These metal pins are interted into the rubber boots and are easy to slip out. Slide your drive over the two remaining pins in the opposite caddy rail and then inssert the two pins you just removed into the other side of the drive. With the pins and rubber boots held in place by gravity, now slide the drive back into the slightly bent caddy. If anything falls, try again.

I was able to get the pins back into the rubber boots with a small pliers and a proper twist of the boot. I had to do this a couple of times until I figured out this method, which was foolproof for me.

This unit takes a lot of desk space. It's actually larger than my six-bay NAS unit, and I keep that on rack.

Other Thoughts: I like the case a lot. I wish it had a multi-color LED for On/StandBy/Off, but that's not documented, so I assume it isn't there. A fair amount of the case space is wasted under the optical drive if you don't use the space for a cooler. I used it for a 3-pin fan-control splitter, and to loom the excess power wires. If you went without an optical drive, this case might be one-half as deep. But, with the interior volume, no worries about heat being retained in the cabinet. You could live inside if you were small.

5 out of 5 eggsNice Case

Pros: This case does it all. 2 3.5" drives, 2 SSD drives and a Optical drive. With support for pretty much any ATX PSU out there and big graphics cards. It also has plenty of fan points and the ability to install a 240mm Rad.

Cons: It's a bit on the large size for using an ITX board.

Other Thoughts: It's a good looking case but a bit on the large size but that's made up for with the cooling abilities. If you've never built in a smaller case it takes a bit of getting used to with how cramped it is compared to something like a full tower.
