    Milestone reached! First "dry" fitting of CarPC

    Yeah!!!
    All I have to say is, "wow"...it's been a LOT of work thus far...what with having to cut down the size of the PC enclosure, redoing the false floor, pulling up the sound deadening to make room for the amp rack, trimming some interior plastic...
    Whew!

    But I now have the PC mounted in place...the amp rack needs a small cut yet, and the plexi amp cover needs a trim...

    After that, I can start on the wiring install, i.e. ground and distro blocks, IGN. lead then sub install/wiring, then on to the dash/display...

    I'm SO pumped right now!!!

    I'll get some pic's tomorrow maybe...

    Okay...got some work done today, and the GF snapped some quick shots...
    Remember, this is just the ROUGH layout!
    The false floor was cut and made PRIOR to having to make some changes to the PC enclosure for fitment (made the enclosure while the car was in the shop).
    I actually found some cuts that weren't square either (!), so the new piece of MDF is waiting to be cut...
    The blue acrylic is actually clear (and machined)...the blue is just the protective film. I'm gonna light up the ends and front on edge (hidden under the floor) so as to add a nice blue glow to all the machined edges...

    I've also since added two 90mm blue CCFL 'donuts' to illuminate the enclosure when the trunk is open...

    (Also, none of the interior carpeting or sub is installed, so the MDF floor looks really undersize)

    I also have to make ALL the cuts radiused and curved...I learned the hard way that vinyling 90 degree inside corners doesn't work very well

    I can't say watercooling a computer in your car is a good idea. The constant vibration and bumping will prob. knock some of those fittings loose eventually.

    WTF!!!!

    I go to install the PC in the car for the first ime, powered up...
    Everything is going smoothly...
    Turn on the IGN, she starts up...good.
    Fire up the amps, plug in the RCA's...good
    Hook up a PC case speaker to the amp to determine which is hi-pass and which is low...static...
    Static!?
    Try a different channel...static...
    Try the other sound card...STATIC!!
    Try the sub...same thing!
    Also, the display has some kinda "interference", like poor shielding or something...

    Pull the ******* thing outta the car, and mount it to the bench power supply...

    Does the same thing...STATIC!!!! No sound whatsoever!!

    Pull the Xonar's and put them in my desktop...they work perfectly...PHEW!!!

    Pulled off the end plate and card support...same...static

    WTF happend to my mainboard!?!
    Everything works fine except the display is a little corrupt and both sound cards give off static...

    Did the mainboard fry somehow!??!

    Gawd, now I gotta find a SocketA mainboard!?!?!?

    Try grounding the MB? Are you using the sound card off the MB? Can you try a PCI soundcard just to see if you still get the static... Troubleshooting is like 85% of the build process.

    I've ran it a 1000 times before I put it in the car though...
    The only difference being the ATX plate/PCI card support piece. But I took that off thinking THAT was causing a ground problem...

    But now my bench power supply is shot, so I can't test any further. I have to go see if I can find a cheapo in town somewhere...

    I'm thinking there may have been a ground short/zap or something? I dunno...I've never seen a PC do this before.
    Should the mainboard/chassis be connected to ground? Right now, it's isolated on a piece of MDF...

    Jeezus...I'm going to kill someone!!

    So I go out of town (45min) to try and find a socket A board...nadda...
    I end up buying a ATX PS for the bench-work, and a used AMD64 (939-pin) on a board with just 2 PCI slots and no serial port (expandable though)...that cost me $90 + $25 for the PS...

    I TEAR the old system apart, and I'll tell you, it's no easy feat with water cooling!!!
    I'm getting very ****ed now...

    Finally get this new system installed into my car case, and it doesn't like my RAM...it'll only take 1 stick...******!

    Get it booted...install all the driver crap, and I'm noticing the SAME screen flicker going on with this unit!!
    WTF right!?!?!?
    Test the audio, and the SAME DAMN STATIC AND NO SOUND!!!!
    WTF!?!?!?!

    Unplug the M4 power supply, and run the ATX unit straight into the board, and guess what???
    IT WORKS PERFECTLY FINE!!!!!!

    And I bet my old system works perfectly fine too!!!!

    So what the hell happend to the M4??
    It's gotta be the 5V rail right? Isn't that what the PCI cards run on?

    Also, I noticed when it was in the car, and 'sleeping', it still had the amps switched on!
    That isn't right is it? The amps are hooked into the anti-thump...

    Anyway, now I have to see about a replacement power supply...which will be the end of the summer for me by the time it's ready to go into the car...

    What a disappointment...
