    Desktop MB as CarPC

    Noob looking to get into the CarPC world.
    I currently have a new Asus MB, processor, RAM and Video card for a spare PC. Given that I have these components in my hand, what are the real drawbacks to using an ATX MB? Do the existing PWS units generate enough amperage to handle a desktop PC MB with a cheap-o video card?
    I currently have a tri-amp car audio system with dual 12's and was looking for something that would allow me to mess with various sound cards and on board sound until i get the controll-ability and quality I am used to with my Pioneer audiophine head unit. Or maybe I cant, that would be nice to know as well.

    thanks

    Naw, the real drawbacks to using a full size is just placement. Lot of people don't have the room for a full-sized board. But psu's like an M2 or M4 should be able to power that just fine, depending on specs.

    i have the room on the back of the sub box. thats not my problem. I guess the depth may be an issue with those large *** cooling fans. cant seem to find the specs on what he mb might draw. guess that has to do with the peripherals as well.... it does make an easy test enviroment though.

    Motherboard power draw is less of a factor as CPU power draw.
    More often than not, if you calculate using the CPU's max power draw, the calculations will more than compensate for the power draw of the motherboard itself.
    Have you looked in the FAQ yet?
    How about the Wiki?

    I am using a asrock x533 motherboard with 1.2ghz P4 mobile and a gig of ram. All stuffed into a (hacked) dell GX50 case. Fits alright, PSU is mounted outside the case, but attached. But dont forget this is a regulation size atx motherboard and PSU. Running through an inverter. I always use hibernation...and once thats done I shut off the inverter, so no power drain. once I finally get my carpc 100% the way i want it...(about 99.95% now), I will set up a relay to auto shut-off the inverter once hibernation is complete.

    thanks and may we continue to spoon feed me...

    i was thinking of taking a dell mb with integrated video and swapping the processor with a mobile version processor for less power draw and possible less intrusive heatsink/fan kit. can a mobile processor be effectively cooled with a small heatsink and no fan. going to an integrated video card keeps my profile low, but the fan/heatsink on a regular processor pushes it back up, hince my thought of using a mobile processor and maybe some mobile like heatsink.

    outside of that the only real concern i have is audio. i am a real freak about the clarity of my music and have invested untold thousand in audiophile grade equipment in my car and will not install a carpc if this is to be compromised... so maybe someone can shed some light on what i might expect in this venue....

    Depends on the CPU and the ambient temps around it, really.
    You can get low-profile heatsink/fan units that are designed for slim rack-mount servers that should cool a mobile CPU variant quite nicely and stay within the space requirement.

    I tell everyone to try the onboard audio first. If it is satisfactory, then great.
    If it's not, then you have the option of adding a soundcard and/or DAC.
