    from completed build Tiny Stealth (For cheap)

    The hardest case I've built in, for sure. Three stars sounds like a bad review, but the case performs brilliantly, doing everything a mini itx case should. Temps were good, grills directly in front of the GPU allowed plenty of airflow. The minus two stars is for simple common sense lacking.

    The SSD and HDD mounting plate only allowed for one side mounting meaning that if the connector of the SSD is facing the wrong way depending on how it was built, your right angle SATA connector won't fit due to it sticking up instead of down.

    The gap between the plate and power supply was just small enough to be impossibly aggravating to get the connectors in as well. The space between power supply and bracket made it too tight to fit the SSD in the slot closest to the PSU, instead forcing the user to mount it closer to the GPU, still not solving the issue with the SATA connector though.

    The cables for the the USB 3.0 and front I/O were far longer than necessary as well as not black. I heat shrinked the I/O cables to make them match the rest of the build.

    And while the case may support a 140mm up front, it will not when paired with a GPU that extends nearly the front of the case. It could, but it won't. the difference so small that the case fan holes needed only to be pushed over a few millimeters and it would have been perfect. However, I needed to substitute a 120mm fan instead.

    This case seemed to plagued by measurements that were done in theory and not in practice. Still a great case, and for the size and airflow, I would definitely recommend it if you're willing to deal with quirks.

    Amazing little case. Looks great, somewhat decent build quality (exceptional considering the price), and fairly good air flow considering the size. Have yet to put a GPU inside, which may affect my rating down the line, but I don't foresee any problems.

    I've seen some complaints about the lack of dust filters for this case, but that seems to mostly be solved for using the positive air pressure from the recommended AIO CPU cooler. I may add on custom dust filters for the PSU and GPU windows when I start stressing the system enough for their fans to actually draw air.

    I'm not a big fan of the front panel connectors. Their placement, attachment, and cabling leaves a bit to be desired, but other than that the case works quite nicely.

    from completed build TARS - Summer 2016

    Great case to build in! It's a bit of a hassle to remove the rectangular panel off the top, and perhaps the build quality could be better, but nothing was detrimental to the final build and at this price I can't really complain. The power button is nice and clicky, the internal layout is well thought out, and I never felt that it was difficult to build in despite the fact that it is so small.

    I would recommend going with an SFX power supply and using the SFX to ATX adapter from Silverstone, as this gives you so much more room to breathe.

    from completed build Wunderkind - r9 390 + ITX = :)

    + Design
    + Unbeatable Price
    + Excellent Airflow
    + Supports standard ATX PSUs
    + Only 11.5 Litres, ITX cases are usually twice its size

    Nothing bad to say about this case, love everything about it, double it's price and i still would of happily bought it.

    from completed build MiniNIX - Dirt cheap Linux box

    I love this little case! Was originally thinking of the even smaller SG05, but this one came up on special and the ability to use a standard ATX PSU rather than an SFX model made the overall value more compelling.

    The downside to the choice of an ATX PSU is that it's really tight in there. You're extremely limited as far as CPU coolers and thus really should consider this case only for lower-powered CPUs, unless you want to cram a small AIO water cooler in there (which is possible). Frankly, if you're running a CPU hotter than 65w you really should opt for a slightly bigger and better ventilated case.

    Silverstone says to limit the CPU to 140mm length if you plan to use the upper drive tray and they're not kidding. You might be able to get away with 150mm if all the cables are pretty low down on the PSU but it'll be really tight. I used a Corsair semi-modular model that works well. Modular is good on these smaller cases because you only need to worry about space for the cables you are actually using. If you want to try to make a bit more space, you could consider an SFX PSU with an adapter plate that would allow more room. Silverstone makes a nice modular one but you do pay more for those.

    A single 120mm fan gets decent airflow through the case. There is a full-length vent grille on the left side where a GPU would go, so anything instlled there should be mostly sucking in air from the outside. There are also vents on the right side and on top. The PSU mostly sucks in air from the top and exhausts out the back. All nicely laid out.

    Minor annoyances: you have to remove the front cover to get at the intake air filter, which requires you to take off the case cover first. That's a total of eight screws which is a bit of a pain for a filter cleaning. The built-in standoffs for the motherboard are not as solidly attached as I'd like. Managed to get one of them spinning in place (it seems to be riveted) and resorted to JB-weld to permanently fix it. My bad for cross-threading a screw that caused it, but still should not have moved that easily. Reset button is a "straighted paper clip" type rather than a real button. Always one of my pet peeves. Still, all these amount to only a one star deduction. For the money it's hard to beat in an ultra-compact case.

    The Sugo S13B is by far the smallest case I could find. The build was quite manageable, and in spite of its small size, everything scaled down quite nicely. Originally I was able to even fit a double wide RADEON 4870X2 in there... (giant massive brick). Obviously the build is compact, and space is meant to be efficient and maximized, but that's the point of Micro ITX~! That being said, nothing was too-tight or unmanageable. I even originally used a full sized CM600 ATX PSU, and it fit nicely, however there was too little space between the PSU and the CPU fan, causing a tug-of-war which likely resulted in the CPU fan being starved of air. After switching to a SF450 SFX PSU, the additional clearance resulted in increased airflow and reduced CPU fan noise, as well as more room/airflow in the case due to the SHORTER cable lengths~!!

    Abandon all your commitments to 'cable management'. (I still wont take off a star for that... it's expected when breaking new territory in the size wars, and they still did a great job... what we really need now is shorter PSU cables.)

    Looks way better in person. IMO

    from completed build Compact 1080p gaming build

    The limiting factor in the choice was a maximum width of 265 mm, since the case has to fit in a tight space. The SG13B is 222 mm wide, fits full-size graphic cards and has a mesh front panel. Other cases like the Cooler Master Elite 120 or 130 were interesting, but this one was smaller and more compact. It's a bit cramped inside, so cable management is almost impossible, unless custom-length cables are used.

    For this price it's hard to beat an mITX case like this. In both size and capability.

    from completed build Hakuma (Mini ITX LAN build)

    Not much to say. Gets the job done and you can fit a lots of components nicely. Case construction could definitely be more rugged and robust but for $40 i think it's too much to ask for. Don't even try to cable manage this case, It is near impossible,there is no cable management holes,and you will be half-lucky to even find a place to cram your extra cables, however this can be easily solved by a modular SFX power supply. This is the cheapest option for ITX build, if you have more money then go drop it on a Corsair 250D or something, but otherwise this is a nice option for the job.
