    Dazed and Confused; Help

    I just discovered this site and it's perfect, but I have a lot of questions. I've looked around but it seems most people are making DIN sized computers that are fairly high end. I'm shooting for simple/basic, easy and cheap. Here's my basic plan:
    500mhz-1gh cpu
    256 ram
    6-ch sound card
    radio PCI card
    wireless ethernet card
    15gb HD
    decent video card
    DVD drive
    mini power supply
    wireless keyboard and mouse
    Win 2k
    Okay, so there's my system. Mobo ideally will be 2 sd-ram slots, 3 pci slots and an agp slot. I plan on building a custom case for space saving. Here's my snags:

    Display: Ideally 10.1 flatpanel mounted on dash and running back to computer. The problem is LCD screens aren't made that small and car audio screens that size are insanely expensive and won't plug into a comp. Doesn't need to be touch screen. Can a replacement laptop screen be wired easily to plug into the video card port?

    Harddrive: How to cushion it against bumps and vibrations. (The car will have stiff suspension)

    General: How to make everything be okay with cold temps. Heat isn't a big problem because it will be well ventilated and not in sunlight. Also the reason for going for a slower processor

    The plan is to mount it in the trunk in a horizontal box (as opposed to a tower). I'm sure in the archives and stuff many of my questions and problems have been answered, but I don't even really know what I'm looking for. I'm just starting to gather info and research. I know desktop computers and have built a few.

    Laptop screens:
    Using ex-laptop Lcd screens

    Hardrive, use laptop harddrives since they are more tolerant to vibrations. I also heard something about mounting them vertically so the read heads wont smash into the platters. Cold temperatures isnt really a problem. If you know desktop computers, you know you want cold :} Unless its too cold, condensation is an innate problem.

    A friend of mine owns a comp repair shop and mentioned that while yes, laptop HDs are a bit more forgiving, they typically don't see a whole lot of vibration turned on. They just sit there on your lap. Plus your legs absorb some vibration. Putting the computer in the trunk, though I plan on putting some soft padding underneath it, will still subject it to some pretty jarring shocks now and then. Vertical mounting would help, but what about taking a tight fast corner? I want a tough, reliable system that will be going into a very fast, highly modded car. I don't want have to drive like I got my mom in the pass. seat, but I don't want to have to worry about wrecking my HD either... Thanks for the links and info!

    edit: HDs and computers apparently are more durable than I thought in cold weather. (removed some sentances accordingly)

    Get some of them seagate drives, most reliable ive ever had. I think they have some "extreme condition" drives too, i dunno.

    mount the hd vertically ... hen suspend the whole pc from the top of your trunk with bungie cords

    (kidding of course)

    what about some thick (2 inches or so) soft foam padding ... like you'd use for a chair or something. You don't have to stop it from moving at all, if you can at least slow the bounce down, a laptop hd should handle it.

    and of course you'll need to secure it to the floor so it doesn't fly in the air when going over speed bumps.

    Hehe, a suspended PC would be interesting to see. Depending on how motivated I am when the time comes, I'm either going to put down some thick insulation to pad/protect the computer or some other squishy mat. I'll keep Seagates in mind.

    In a different direction, what about my setup? Too much, too little? All I want is MP3 and DVD playability. What kind of wattage would I need? I've seen some people post some DIY Opus 90w power supplies (psu=power supply unit?) and I may try that, unless I need more juice as I'm running a desktop PC rather than a DIN PC.

    with a pentium III (i assume)
    a dvd drive
    3 + pci cards
    a agp card
    some usbs and what not, you might be border line on deciding between a opus 90watt and 150watt. I would get the 150 if I were you, then if you ever decide to uprade/add components you will still have enough power. The 90 might be fine though (what Im guessin), but id still go for the 150.

    But keep in mind these are about $190 for an opus 150, and $150 for a 90watt, and in your first post you stated " I'm shooting for simple/basic, easy and cheap." So mabe you might want to look into more affordable/easier
    92 Taurus SHO - Daily driver - Epia M10000 80GB 512mb 7" touchscreen, Opus PSU etc

    93 Black SHO - 30mpg cruiser

    90 Silver SHO - 419whp fun/project car, CarPC to come (for tuning)

    Right, there are a few posts on making a cheaper version, but electrical wiring is not my forte to say the least. I'd really rather not go the inverter route because they're big and clunky and suck up a whole lot of juice. I would just go with a 160w mini atx power supply but then I still have the inverter issue. Are there any knock-off Opus's out there?

    How about using those platforms that you put personal CD players on to use in the car to mount the hard drive? I used to use one at uni, and took it apart the other week to clean it (had engine oil spillage in the boot... ). Anyway, it's basically a platform mounted on four little stretchy rubber gromet-type things and allows it to move around like forwards, back, left, right and up/down to a degree. Could work.....

    Interesting idea, I'll look into it. Thanks.
