I have had bad luck with cheap case/power supply combos, so I avoid them like the plague. If you read the hardware reviews you can generally figure out the junk power supplies from the good ones. The junk power supplies will barely make it beyond the warranty period. If I put a PC into a machine, I don't want to get a call back on that PC for at least 2 years, preferably 3 or more, otherwise my reputation takes a hit and it jeopardizes future work. Most of these PCs are never turned off. Intel is warranting their boards for 3 years now, so if the power supply holds up, all should be good for at least 2 years after the initial burn in. The wide range input DC supplies are quite expensive. http://www.mini-box.com/DC-DC For instance the M3-ATX and the M4-ATX are nice power supplies but they are pricey at $69 to $89. I have an M4-ATX and while it does work well, it is still $89. The M3-ATX is good for 6-24 volts with 6 volts only being ok for short periods (while cranking the engine). This new Intel board is good for 8-19 volts DC +/-10% and normally a car with a good battery and starter will not drop below 8 volts while cranking so this board could be run directly off a car electrical system without a power supply, and it should survive an engine startup - saving $69 for the M3-ATX. I think that Mini-box just lost a bunch of business! That board is also very low power. A lot less than a D525MW. Good for mobile applications.
