5 out of 5 eggsNo issues

Pros: Nice design.
Good paint job, inside and out.
Fits mini ITX form factor perfectly.
Sides and top planes are removable for easy access and assembly.
Good size (and quiet) air intake fan with removable filter.
Just barely enough room for a full sized PCIe GPU (check your measurements though). Tested with a Nvidia 9800 GTX card. It does not fit my old oversized 8800 GTX.
Regular ATX power supply fits perfectly.
Internal drives have an external access port area, which is handy, but not overly usful as you still have to open a side to get at the power/data cabling.

Cons: Large empty "void"-ish zone behind the front air intake fan. I put my messy cable assembly in there, but an enterprising individual could probably add some sort of internal drive expansion structure inside.
The case does not have a large number of slots for internal drives. It supports 2 drives (either 3.5" or 2.5" form factor).
Sides and back air vent have no air filters.

Other Thoughts: I had no issues with this case.
The case fan runs very quiet.
Using a fanless Zotac Nvidia 730 GT video card, the loudest component is the stock Intel fan on my Pentium G3280.
This case can be used for a mini-ITX gaming build very easily, though with little room for storage or hardware expansion.

5 out of 5 eggsGreat Case

Pros: This is a great case for mini-itx. It holds full size cards and PSU's, all in a miniature package. I love that it has easily remove fan filters everywhere. Also the large intake fan in front is whisper quiet and moves a lot of air. The side exhaust fan is mostly silent as well. I'm just very pleased with this purchase.

Cons: The only con I can think of is that since full size components are squeezed in a small package, you need to plan the build VERY carefully. Measure twice and cut once. Also it would behoove you to totally disassemble the case before doing the build so that you have room to work. Leave the 5 1/4 drive tray off until last, as well as leave any video cards until last. And install your PSU first and poke the cables you need through. Next install a SATA cable on your hard drive and insert that through tht bottom. THEN you can install the mobo and start hooking things up to it.

5 out of 5 eggsCorsair Obsidian Series 250D

Pros: Aesthetically, very pleasing. From a build perspective, it was easy. My 12 year old son got to use this case as the basis for his first solo build. ( A new HTPC for our living room. )

A multitude of tie down points for the included zip ties. We have a Blu-Ray installed and had plenty of room for a decent sized air cooler. We had a Scythe Big Shuriken collecting dust, that had barely been used, so my son used it for CPU cooling.

Comes with (1) 120mm and (1) 140mm case fans. I did have my son replace the stock fans with (2) Gelid 120mm PWM fans and a Rosewill 140MM PWM fan. Used a 1 to 3 Silverstone PWM Fan cable for those.

Excellent cooling. Running an ASROCK FM2 A88X-ITX+ mobo with AMD A8-7600 APU, GSKILL Aries 8gb (2x4) 2133Mhz memory. House temps stay at 24-26° C (76-78°F) Mobo temp staying right at room temp, with APU temp at idle @ 32-35°C. My son set up the fans to run standard mode. You have to be within 3-4 feet to hear it and even then it's the faintest sound.

Cons: None for me.

Other Thoughts: I ordered another one to build my daughter a new PC as hers has reached the end of it's usefulness.

The Power LED is very bright, however the included utility software from ASRock has a function where you can turn the Power LED off. The Hard Drive activity light is dim.

This case is very well made. It's not cheap or flimsy.

I would recommend a modular or full modular power supply. You could use a non-modular but you'll need to be creative in securing excess cables out of the way. Can definitely be done, but better for airflow with less cables and looks better with modular.

Couldn't be more pleased with this case. I would definitely recommend.

5 out of 5 eggsI'm happy with this case

Pros: Fit all my components perfectly
Plenty of room for multiple drives
Quick panel removal

Cons: Front USB ports upside down, not a big deal but no reason to be this way.
Too Bright LEDs
A little larger presence than I had imagined - sort of a large block of a case.

Other Thoughts: Not sure why people complain about space in this case. This was my 1st build and I had no problems hiding cables or fitting components; I am not a small guy so not sure what others found problematic. Most cables ran under board; it was a little tight but nothing that bothered me.
If you are planning an AMD Linux build you'll find few mobo options for this size that support the OS officially. Hasn't hurt me except for limiting OCing and other tweaks. Has a GIgabyte GA-F2A88XN-WIFI mobo, AMD 7850K APU, Scythe Big Shuriken cooler, Artic F12 fan and a Rosewill PSU in it. I often unplug the case fan with no issues to quiet it down.

5 out of 5 eggsHappy Customer

Pros: * Aesthetics
* Design
* Internal Space
* Dust Filters

Cons: * None

Other Thoughts: Fits a Sapphire R9 290 Tri-X or XFX R9 290 Double Dissipation, over sized video cards. Fits an EVGA G2 Supernova 1000W PSU easily. Core i7, multiple SDD's, a disc drive, an aftermarket cpu cooler.

I've been very pleased with this ITX case. I usually like to include cons but for this case there aren't really any cons that stick out or are worth noting. This case looks good, its small, and yet it has the internal space to fit full-sized computer hardware.

5 out of 5 eggsPacks a lot of hardware for a Mini-ITX case

Pros: This case is very easy to build in with all the panels and the front fan removed.

It can seriously fit a lot of hardware. I built this with Corsair's H100i, their 850W modular PSU, and a GTX 970. Everything fit with no problems, and there's still room for 2 SSDs, 2 HDDs, and an optical drive.

Front, side, and bottom intake filters included. Side vents allow your GPU cooler and radiator to draw air directly from outside.

I love the understated design.

Cons: Cable routing is pretty much out of the question; you'll have to jam everything under the 5.25" bay. I recommend using a modular PSU.

The spacing and configuration of the drive caddies isn't ideal. HDD/SSD connections are hard to plug in unless you remove the front fan. If you're using both SSD caddies, I recommend using extensions for the SATA power cables to make them easier to plug in. Right angle SATA connectors might cause some clearance issues.

Although there's space above the CPU, I'm not sure you can fit a large tower cooler in there. An all-in-one watercooler is really the way to go.

Bulky for a mini-ITX case. It's too small to leave on the floor but somewhat awkward on a desktop. It's still plenty portable for LAN parties though.

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
