    well the DVD drive is self-powered, too.. I'll just have this IDE -> USB adapater (on ebay for $29) to convert and run the signal over the longer distance which USB can take me..

    LOL, that uses completely different cables (since you certainly burn a standard USB cable with that kind of power). I'm not aware of any system boards using this standard so in a carPC environment, you'd still need an external USB+Power hub and that hub would still require external power (sigh). Moreover, since none of the typical USB devices support the USB + Power standard, high current devices would require an adapter to suck the power off the USB + Power cables. This looks like a no-winner, at least in the short term.
