MINI-ITX and the Future of PC Case Design? 164
An anonymous reader writes "One of the interesting things to come out of the recent Computex electronics show in Taiwan was striking new PC cases — in particular systems built around tiny Mini-ITX boards. What may have once been regarded as the weird little brother of the more common Micro-ATX, the popularity of PCs built with these boards seems to be gradually building. This year at Computex saw the first Mini-ITX boards to support USB 3.0 and SATA 6Gbps, and a variety of new shapes and styles in both Micro-ATX and Mini-ITX case design. This photo gallery shows some of the more striking examples of these new PC cases from Computex, including one that appears to be modelled on an Xbox 360, and one with a VESA mount for strapping to the back of a monitor. Interestingly, while these designs have usually been associated with home theatre system PCs, or for saving space on office desktops, there is also now a trend towards pushing 'gamer' features like windows and multiple fans into these small form factor cases."

So ya, I agree with parent. MAKE THE CASES SMALLER!

I fail to see what's so striking about rectangular boxes. These aren't really any different from what we've been seeing for the last 10+ years or so. Some of them are a bit stylish, but I don't see any new innovations in the photos posted in TFA. What's so striking about these, exactly?

No kidding. PC design needs more Dieter Rams and less Liberace.

Looking at the "striking examples" I have to ask, does anyone other than 14-year-old gamers build computers anymore? Whatever happened to six flat sides? A basic cube-ish design is inexpensive to manufacture, easy to open up and get into, minimizes wasted space (are any of your components curvy? no? then your case shouldn't be either!) and you can easily lay it down, stand it up, or put things on top of it. I can understand no one wanting to put together a gallery of beige boxes but it would have been nice to see at least one clean example.

having a large case actually makes it harder to move the air since there's more volume to be moved.
No. It is easier to move a volume of air through an unconstrained space than it is through a constrained space. Just try breathing through a 2-inch PVC pipe and then a garden hose, and tell me you're getting the same amount of air for the same amount of work performed by your lungs. Ducting is essential to cooling inside of a case (thus the enclosed space), but wider-open ducts are way less of an impediment.
Small cases also have the disadvantage that the airflow is rarely straight-through: there are often very tight turns inside the case required to pack so many components inside. Every time the airstream has to turn, it slows down. An open mid-tower ATX case has very few blockages between the front and back, so airflow is much less impeded.
The low volume of a mini-ITX case allows it to exchange it's hot air for cool air much faster even with low RPM quiet fans.
That logic is terrible. Just because you can replace the air inside of a case faster with air outside does not mean you are cooling things faster. It's not the air volume of the case that matters, but the continuous air flow that cools things down. The size of the case has NOTHING to do with cooling potential, so your sentence shows you have no clue what you are talking about.
As far as airflow goes: smaller cases are typically limited because they cannot use larger fans - and since quiet operation is usually the goal for these things, you are severely limited by how much airflow you can push through while maintaining silence.
Most MiniITX cases use 60mm to 80mm fans for airflow, as-opposed to the much more efficient 120mm (and larger) fans used on quiet ATX cases. It's a well-known fact that the larger an axial fan gets, it can generate more CFM per watt / per decibel. Smaller cases just can't leverage that fact, and so they are limited to low-wattage operation only.
I'm not trying to disrespect your setup, but PLEASE don't spread bullshit you know isn't true. The only reason your MiniITX system is silent is because you started by paying extra for (or compromising on) low-power components (like your mobile core 2 duo, which is slower than desktop equivalents, and costs more). You really can't build anything like a powerful gaming system or a 6-core processing behemoth, and expect it to remain silent inside of a MiniITX case (it's going to sound like a wind tunnel). But you have the potential to do this in a full-sized case.
