    i think i know what i want!

    now you guys can tell me what im doing wrong!! lol

    ok so iv browsed here for a while (signed up yesterday) have spoke to my mate who knows what he is on about on many occasions.

    ok so i will have a lilliput hdmi touchscreen fitted to the dash, wired into this will be a alpine pro hub via composite, and into that will be the Alpine PXA-H701

    which effectively will give me a very expensive radio.

    now in comes the pc side of things, after much deliberation iv decided id love to build my own incar pc inside the shell of an old nintendo NES console (bit of retro cool) my mate says its not completely out of my grasp! anyway, this is the motherboard i have in mind http://store.mp3car.com/ZOTAC_G41ITX..._p/mtb-065.htm

    so with a hard drive connected to this probably a 250gb one, this will give me a pc? the first issue im not fully undersatdning (yes after searching) is power supply, the motherboard has a 24pin power supply, will i need to buy a case and strip something from there to begin my 12v power convertion??

    im planning on connecting an external bluray player which will be mounted in the dash (hence why i wanted a hdmi screen and a motherboard with hdmi output.

    the sound on the other hand id like to be as of higher quality as possible so was thinking of adding this http://www.alliedsdirect.com/computi...ound-card.html so i can connect the audio from the pc to the H701 via an optical lead.

    now im assuming i will need to place fans etc inside the casing to cool everything?

    and one final query, hopefully ill figure a way of wiring it so it turns on with ignition (is this best) but im a bit stumped because surely if in car pcs are wired like this, what about the whole shutting down of the pc? or do people just turn them off??

    sorry my post is so long, but would appreciate any help.

    lots of ideas, but they need more refinement

    i don't remember exactly how big the nes cases are, but i don't think you'll be able to fit all the pc components in it.

    the motherboard you selected requires a 775 socket series processor-- something like a intel celeron, or pentium processor.

    depending on what you want to do with the pc, this can be way overkill.

    my setup experience: i first started with a intel 945glc board with integrated atom processor-- this worked great for music, web, and video fine. i ended up ditching it for a carpc after i tried running audio processing on it-- audio processing is very hard on a cpu. (i am actually using it now as a home computer, and it handles everything my family can throw at it)

    i have since upgraded to a board with a 775 socket (zotac 9300 mo. bo.) and am using a dual core pentium processor. this handles the audio processing i am doing very well..

    from my experience, i will say that 90% of all car computers do not need any more cpu power then what a atom/ion processor can provide-- if you want more, that is up to you...

    for audio, the onboard audio will work good for most people, but i think that card is slightly overkill for just using the optical out-- there are plenty of other cards that provide optical out that would be much less, and would have no noticable audio quality loss over optical (there are certain losses, but nothing you would ever be able to notice without expensive measuring equipment).

    also, unless the old nes cases are at least as big as the older, black X-box cases, there is no way that card will fit with a mo.bo., and hdd

    audio quality is relative-- i would say that a card like that will not be worthwhile unless you have, or are planning at least $1,000 in speaker/sub upgrades..(not including amps) anything less might not have enough clarity to even allow a noticeable difference between the zonar, and a much cheaper card.

    and if you have, and are planning to keep the stock speakers in your car, unless it is a "premium" audio system, onboard audio will be fine.


    for the power supply, all automotive power supplies in the mp3car store, and elsewhere(for example, the m1, m2, m3, m4, and ds-atx, ), have leads that attach to the mo.bo.'s power wire to turn the board on and off depending on the ignition position. they also regulate the voltage so that the computer can use it properly in the volatile car environment.

    cheers for the reply mate.

    the speakers will definately be replaced by some very high end components, the car will be used for competitions and shows. i found that sound card via google by searching low profile optical soundcard, could anyone recommend me an alternative soundcard which includes optical out

    as for the mo.bo. it was picked from the mp3car store again simply for its hdmi output, so do the mo.bo.'s not come with processors when bought from the store?

    i can live without the nes casing, just thought itd be quirky

    the boards with atom, or ion processors will usually come with the processoer already installed.

    the reason for the manuafacturer(Zotac) for not including it is so that you have a larger option of different processors to use.


    what exactly are you planning on using the car pc for?

    Atom boards will almost ALWAYS come with processor installed, simply because it's sold as an integrated CPU solution. Ion is a chipset, not a processor.

    Zotac didn't include a CPU because it's socket 775, which isn't designed to have an integrated CPU. (That's why there's a socket). You can always bundle a CPU if you want, they just don't plunk it into the socket for you. It's really easy, just read the motherboard manual if you've never done it before. It's (pretty much) fool proof.

    sorry for the late reply!

    the main use for the pc will be for music, high def video, and internet.

    im sure in time i will learn what else i can do with it!

    i emailed mp3car store and they have suggested the "power bundle"
