3 out of 5 eggsAdequate, but not without troubles

Pros: 1. Attractive exterior
2. Power supply has held up under moderate strain
3. Viable HTPC option

Cons: 1. Tight spaces and short cords
2. Essentially no documentation
3. Power supply not sufficient for some builds

Other Thoughts: Buy some SATA extensions to go along with this case; installing a dvd or bluray drive will be a slight challenge.

4 out of 5 eggsNot quite stellar

Pros: Good looking, and seems to be roomy enough though i haven't built it up yet

Cons: description is lacking and there are no instructions

Other Thoughts: As others have indicated, the lack of instructions is somewhat frustrating. Also, the description, especially with respect to the power supply, is lacking. This is an SFX12V supply. So, what does that mean to me? Well, i go look at other SFX12V supplies and not all of them have a 2x4 (8-pin) CPU 12V supply plug which is what my mATX MoBo needs. In addition, some of the reviews of this case mention an incompatibility in this regard. So, without knowing, and not wanting to take a chance, i ordered a 4-pin to 8-pin adapter (said it was a fan power adapter, but some online searches led me to believe it would work for the CPU power as well). Well, that was a wasted purchase... this case has two 4-pin 12V CPU connectors that are designed to be joined together for an 8-pin application. You can use just one for the 4-pin application. Oh well.

Bottom line, the power supply that comes with this case will work for either 4-pin or 8-pin CPU 12V MoBo plugs.

The fact that i did as much research as i could possibly do (i even tried asking newegg, but they don't have tech support any longer), and STILL couldn't determine if this would work with my MoBo, leads to the deduction of an egg... seems like instructions and a better description is low hanging fruit to get that egg back.

5 out of 5 eggs$60 WITH 300 WATT PSU!

Pros: Perfect size. Just the right size for a small case. Micro ATX so you can get a less expensive mobo. LARGE POWER BUTTON! Love it. Finally someone built a case with an easy large power button.

Cons: usb 3 would be nice but not necessary. The fan shroud thing is weird. Would like 8 rubber feet so I could fill all the spots for feet.

Other Thoughts: For $60 with a 300 Watt power supply AWSOME! Way to go INWIN!

5 out of 5 eggsGreat With The Right Hardware

Pros: + Works well with narrow mATX boards
+ Small, quiet power supply
+ Can hold more hardware than listed (see other thoughts)
+ Shallow footprint good for placement on a shelf or in entertainment center
+ 3 SATA connections on the PSU

Cons: - Motherboard standoffs are tack-welded, no choice for placement (see other thoughts)
- Two of the 3 SATA connectors are on the same cable, 3 or 4 inches apart
- All pieces and panels are designed to align just right as they come together, but it's often difficult to tell until you see something doesn't fit properly

Other Thoughts: You can't expect every piece of hardware to fit in this case. Some tips:
* Get low profile RAM, or at least something where the heat spreader doesn't stick way above the PCB
* Get a narrow mATX board (I used the ASRock FM2A88M-HD+)
* Use the stock CPU cooler, or one that is lower profile. I would suggest completing the build before buying an aftermarket cooler
* If you plan on using a discrete graphics card, get a more powerful SFX power supply
* Optical Drive, the shorter, the better
* Motherboard standoffs are welded on to a secondary plate. one was misplaced for my motherboard, so I had to use some pliers and snap it off. the lower right corner of my board isn't as supported as I would like, but it beats shorting it out.

One thing is nice, you can fit considerably more hardware in here than listed (with a little modification) if you get the right stuff.
Along with the recommendations above, you can get a shallow card reader for the smaller front panel, and fit one or possibly two 2.5" drives behind it.
Also, if you have no use for the front audio ports, the panel that fits around those and the USB ports is a standard 3.5", so you could put the shallow card reader here instead (some modification required for the internal bracket), and leave the blank on the other bay and fit another 3.5" HDD... Or, like me, you could get item # N82E16817994161 and get two front USB 3.0 ports along with a bracket for two 2.5" drives.

Even with the additional hardware, I had no problem fitting the shroud in (thinking it helps keep the case quiet, if nothing else). Just be patient, and plan your installation. this isn't the tightest fit case I've used, but it isn't as easy as a big-ol' mid tower.

5 out of 5 eggsCompact & Conservative good looks

Pros: Attractive
Compact
Light weight
Sturdy case
Inc. PSU

Cons: USB 2.0
No media reader
PSU only 300w

Other Thoughts: This is a good case for those looking for a PC with a small footprint. It is well built , good dimensions and nice to look at (the blue led ring that another reviewer found "obnoxious" is part of it's charm IMO) . I did not have much use for the cooling adapter and removed it to increase useable space; the case should come with a better cooling solution then the provided adapter which I think is maybe useless anyway. The PSU mine came with does have a hefty feel to it and I've had no issues with it after 9 months use but would like to see more watts.

The case did not come with a media reader but there is a 3.5 inch bay at the very bottom that is accessible thru a small hinged door that could be used for one.

I have a 2.5 notebook drive in mine but it does have room for a 3.5. If you plan to install two drives use notebook drives or SSD's stacked. I have a MSI board with an AMD A8 cpu installed.

Keep in mind the small dimensions of this case and don't try to do too much with it and you should be fine.

5 out of 5 eggsLittle Black Box

Pros: Love these cases! They're small enough to hide behind most 22" and above monitors, they look nice and with the right hardware they are nearly silent. Since I started using these cases over 18 months ago, I've ordered 200 for my organization and side business.

Cons: The only issue with these towers is the relatively small interiors. If you are not careful, they can be a pain to work in.

Other Thoughts: I use these for basic office PC's. The hardware I use is a 65W or less CPU with onboard graphics, 8GB RAM, and a SSD. No optical drive needed.

3 out of 5 eggsNice case for 24/7 HTPC PSU fan died at 5 months

Pros: Great size and reasonable good looks for an HTPC. My wife asked me to kill the disk access indicator (which was easy to do). I had no problems using an AMD A10-5800K and stock fan.

Cons: Yesterday, at five months, we started hearing mechanical noises. Pulled open the case and the PSU fan would periodically jerk forward a little and with a loud buzz and with no obstructions (I can turn it by hand, but it is stiff).

Other Thoughts: In Win site says that their rma is for direct customers only and to see where I bought the box for warranty. Newegg of course says to see the manufacturer. I need something now so I ordered a new (non In Win) SFX psu but I'll try to get the existing PSU replaced and keep it as a spare (or use in another build). We'll see how In Win responds.

Manufacturer Response:

We apologize for any inconvenience that you have experienced. This is not correct for RMA that is for direct customer only. In order for us to assist you promptly, please kindly contact our RMA dept at 909-348-0588 ext 741 or email us at customerservice@in-win.com for the RMA number. We will process your case as soon as we can. Thank you.

2 out of 5 eggs

Pros: Ordered this to build a HTPC.
- Compact case
- Quiet and cool

Cons: This case has given me problems since I first purchased it. There's a problem which causes the computer to short out on the case. When I was first building my PC I was baffled as to how everything worked when I had the case open, but as soon as I closed it up, it wouldn't even turn on. I somehow managed to get everything in position so it didn't short out, but then about 8 months later it just started shorting out on itself again for no reason. I'm currently using the PC with the side of the case off and everything works fine, but you know, I'd kinda like to have the thing closed up.

Other problems:
- Doesn't come with an actual instruction manual and assembly is unintuitive.
- Obnoxious blue power ring LED (easily obscured, just annoying when watching a movie in a dark room)

So it would be 4 stars from me if not for the whole not actually being able to operate the computer with the case closed up thing. I'm very annoyed, but not annoyed enough to pay for shipping/replacement costs.

3 out of 5 eggsGood, now that I never have to open it again

Pros: - Fine user experience, once built
- Slick looking, great for HTPC's or sitting on your entertainment center
- Nearly silent PSU fan (hopefully, at 300W)
- Sufficient cooling (without cooling plate)

Cons: - Frustrating builder experience (see other thoughts)
- no screws included for mobo or drive mounting
- no instructions included except pictures for cooling plate, barely considered instructions at all
- cooling plate did not fit with my choice of motherboard or RAM
- side panels include chunks of the top and bottom of the case, making it incredibly difficult to tuck away unwanted power cables in the bottom bay (exterior 3.5) because they stick out the bottom.
- 3 total drive bays, only 2 sata power connectors on PSU, not a problem for me, but maybe for some
- motherboard standoffs already mounted, but none on the bottom right where I could have used support while plugging in many connectors.

Other Thoughts: There is a "cooling plate" inside this case that directs the air from the CPU fan out the side vent. It has two parts, the frame, and the adjustable intake. The intake is supposed to adjust the aim to account for the different placements of the cpu and fan on different motherboards. Mine was too far south on the motherboard, even with the available adjustments. After I ditched the intake, I realized I still couldn't completely close the case without squeezing really hard. It turns out my RAM was 2 or 3mm too big, and was pushing on the frame of the cooling plate. (This may have been my mistake, but I saw no hits of needing low profile memory.) So I got rid of the frame too. It was almost completely blocking the back vent anyway, and removing it let me route my optical drive cables somewhere besides right in front of the cpu fan. Now I've overclocked my A8-5600k from 3.6 to 3.9GHz, and it's at 61C under load with the stock cooler.

With it completely removed, the cooling seems fine, but the case is still difficult to close completely. But the lone fan, my CPU fan still blows half of it's air directly into my optical drive.

I really hope I never have to open this case again. If I don't have to, I will be satisfied. It was frustrating to get almost no instructions with a non-traditional case. I almost broke off part of the front panel without them. A single diagram of the case interior and 10 screws would have gone a long way with me.

If my optical drive fails because of heat, I will surely return and give this a 1 egg review. Otherwise I can't really give it more than 3 eggs. This isn't a horrible product, but I see few signs of a quality manufacturer. I want a company to go out of there way to satisfy a customer, not risk short changing them to save money.

5 out of 5 eggsHas been running 24/7

Pros: Compact and nice looking case.
I'm not into "bling" and prefer to have a silent and non-distracting case (think office environment) but the LED light around the power button grew on me so I left it connected.

Cons: Low quality power supply, but it has lasted over a year now and cannot be heard over the stock Intel CPU fan inside the case.

Other Thoughts: In the future I will just bu separate case and PS.
Again .. the included PS has run 24/7 for a year+ without issue, so it's just a preference - not a complaint.
