    That's exactly the same one as in my Procase 3688 and after a few discussions on here it needs 11.4v-12.6v, i.e its not recommended to hook it directly to the car's 12v supply as that can get as low as 7v while cranking the engine and as high as 18v during voltage spikes.

    The one thing that hasn't been addressed.. for those of us powering epia boards with laptop hard drives, are these safe to use directly in the car? Since the 12volt line isn't required by the motherboard nor the hard drive everything will be powered off the 5volt and 3.3volt busses. Do these voltages stay stable during the cranking/running cycles in vehicles?

    just a random thought...

    Jason...are you sure about the 12V not being used by the motherboard? I'm not doubting you, I have just never looked into it. If so, this could explain why some of the (brave) folks are successfully running their internal Casetronics/Morex PSU directly from their car battery (ditching the brick). I would assume that the regulators in the internal PSU would be able to tolerate a wider input range than the +/-5% that Casetronics states in their specs.

    Could you double-check the 12V thing and let us know. This may give us more freedom on a way to kick the brick.
