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."

Or put to it this way, if you have to put it in a large case to allow for enough air flow, what the point in having such a small motherboard?

These boards are getting very close in size to some of the microcontrollers I've worked with in the past (HC12, etc) It was just for college, and I've no real world experience in them, so I was wondering if some of the more advanced hobby builders or professionals could comment on this:
These boards are getting much lower in power-consumption and seem to offer a lot more in terms of flexibility, and by providing the ability to run standard operating systems through the use of SSDs you have available to you a vast number of open projects which you can tailor for your purposes. The cost is now around $100 or so, which is what I remember the microcontrollers costing.
So, given the choice between some of the newer mini-ITX systems, what are the advantages that a basic microcontroller would offer?
(Again, it's been a while since I did anything with them, so I might be missing something big)

...to building my own laptop? Ok, I can technically do this now, but parts are often motherboard specific, with ITX and smaller form factors it might be possible to buy generic laptop cases/batteries and swap parts as it ages.
Well, I can dream anyway...

These mini-ITX units are more or less laptops in a slightly larger case and without an integrated monitor and keyboard. They generally have to use low-TDP processors (45-65 watts or less) because you can't fit a high-capacity ATX PSU in a mini-ITX case and the small fans required by the small cases can't dissipate the heat from high-TDP parts. They are popular for HTPCs and business desktops since you generally want a small, unobtrusive machine that can be easily connected to a separate monitor, has standard, replaceable parts, and does not need to be particularly powerful. But you certainly won't see anybody who does much for heavy work using one of these machines. They'll continue to use larger desktop boards and cases that fit high-TDP, high-performance parts and multiple disks.
Using a larger case to fit a smaller board is not necessarily a bad idea. Larger cases can accommodate more disks, a larger number of larger fans for better cooling, and give more room to work in while building and maintaining the computer. Mini-ITX cases are seriously small and a real PITA to work with, but putting one of those boards in a micro-ATX case solves that problem very well. I learned my lesson trying to shoehorn parts into cases that were technically large enough but a very tight fit with everything installed and now almost always buy a case that fits a board one size larger than what I'm intending to install. A good desktop setup with an ATX motherboard, a decent GPU (which is generally about 9-10" long) and a few disks is a tight fit in an ATX mid-tower case but has plenty of room in an Extended ATX-capable full-tower case.

Yeah, I was paging through that slide show thinking "hideous, hideous, also hideous ... and hideous." Are these the more notable ones because they're fugly, or is that just the state of the art? ... such as the "Deco Box" or the "Rundfunker", or even toaster fer cryin' out loud!
I mean, individuals can make cases that are so much more attractive

I was looking for a case for an htpc recently, and the only useful case I could find that didn't come with un-covered front (usb, fiwi, headphone) ports was a Silverstone LASCALA LC16M. Seriously, one case?

5 years ago I had the idea to build a briefcase sized laptop. I was going for style over performance, and changed my design half-way through due to the expense (I was just out of college and still on ramen budgets) so I didn't invest in a laptop LCD. However, I kept the laptop formfactor for my internal components. Here is what I did:
Using only non-laptop components. I found a very slim power supply that was typically designed for a 1U rack. This ran alongside the motherboard and was about as tall as the entire board (PCB+RAM height) I used a board that had built in video,ethernet,sound so I wouldn't have to have any vertical PCI cards. Since I didn't have to use the PCI ports, I placed the HDD over this location and it rested on the plastic risers (Top of the HDD on the plastic) I couldn't do much about the RAM but it didn't stick up above the capacitors very much. I used a processor heatsink with a fan since this would let me get away with a smaller heatsink, though the processor in the board would probably run with just a basic heatsink and no fan. I used a standard 5.25" DVD drive which sat next to the power supply and next to the motherboard.
I took two aluminum sheets and drilled holes to attach the motherboard to the bottom sheet, and the HDD, DVD, and Powersupply were attached to the upper sheet. They were then sandwiched together and I used short bolts to hold the two halves together.
The result was something on the order of 12" x 12" x 1.75" (can't remember the exact dimensions). Due to the way the components were sandwiched, it was fairly robust and I was able to mount it with shock absorbers inside a travel case.
Later when I had more cash, I built it into an ammo-can and included a fold-out monitor and keyboard/touchpad. It turned into an AMAZING little portable server for things like LAN parties.
With it's 1'x1'x1.75" dimensions, I'm sure that I could have easily put it inside a briefcase and built in a display. I just went with the ammo-can because having a truly rugged portable computer was useful to me. (in addition to being waterproof)
With today's boards and SSD storage It would probably be no trouble at all.
