    WuNgUn PIC'S-Bench-bleeding the water-cooled carputer (almost finished!)

    Assembly so far is almost complete...just have to do some wiring for the fans, fan controlers, pump and monitor (off the relay), and connect the M2-ATX power supply.
    Here are some pics of it bleeding out the air in the lines...

    System is a Abit NF7-S (rev.2.0) with FSB at 400Mhz (1Gb, 400Mhz DIMM's) with AMD Athlon overclocked to 2.2Ghz (3200+)
    Video is an ATI 9700 Pro
    Audio is two ASUS Xonar PCI cards
    HDD is 320Gb Western Digital (currently over 5,000 lossless WMA Pro songs + some DVD-A (5.1)

    A pic of the distribution block, voltage regulators and power relay for the monitor, pump and fans...


    Here you can see one of the thermal fan controllers and the power supply and pump. Green wire is the amp switch-on lead. It fires the amps after the PC has booted so there isn't a loud "pop" when the hardware is initialized...


    Here is what you'll see thru the trunk floor (false floor)...this actual unit sits where the spare tire used to be. Note the fill port in the center...


    Swiftech resevoir...this actually works really well at releasing trapped air.


    Another overhead shot...


    A good look at the plumbing...


    Later on today, I'll power up the M2 power supply and check the bootup.
    This will be ready to install by tomorrow.

    And here are a few shots of the amp rack, ready to install...filthy dirt!
    (Mounted to linseed oiled birchwood)

    The top pair of interconnects on the right are SLIGHTLY too long...I should take the time to shorten them, eh?

    Are you seriously planning to power everything off of the M2? I notice you say "voltage regulators", but is that whole PC powered off the a wimpy M2?

    Looks good though. I am guessing there is a plug for the whole uptop so random crap doesnt fall inÉ

    If you have a close look at the power distribution block, you'll see the monitor, pump and fans and powered independently from the M2. The Bosch relay turns them all on (via the M2)...
    There will also be a low-power mode, wherein the pump and fans run off a 8V regulator instead of the 12V to conserve battery life...it's switched from 12V to 8V with a switch in the trunk thru a 5-prong relay...

    So essentially, the M2 just powers the board and HDD...
    However, 4 PCI slots are occupied, one of them with a 4-port USB card...

    Dead sexy cabling job on the amp interconnects. What wire and connectors are you using?

    Thanks...it's all home-built.
    The RCA's are locking Nakamichi's...
    The phono jacks are Neutrix
    Cable is THX grade Monster Cable...2 terminal with a drain and foil.
    And then just the flex cable sheathing and shrink wrap

    I had to remove the barrels on the amp RCA's, as they just sit too close together...
    Looks cool though...

    I had plans on some real exotic interconnects, but I don't think they'd be much good in a car (i.e. noise and interference). And needing 8 of them, VERY expensive!

    Eek!
    Just ran the calc, and I'm getting at least 225W at peak...
    Am I ****ed!?
    CPU will hardly see over 50% usage...
    Vid card won't see any 3D acceleration...

    Max output on the M2 is 160 or 170W, and my "typical" normal useage would probably be around 110 to 120W, with my Absolute Maximum Worst Case Scenario around 230W, which would probably kill the lil'bugger.

    What other affordable options are there?

    Nevermind...just bought an M4
    Surely that'll be enough!
    Anyone need a M2??

    225W on what rails...

    I would not run that system on the M2 like you figured out. The M2 works perfectly when used for systems that dont touch its max specs. But if you use more, you generate more heat on it, more heat less power, tries to pull more, gets hotter, and kaboom. The M2 fries and usually the spike takes out the mobo and/or cpu as well as the RAM if it is cheap and unprotected.

    I dont know much about the M4, but if you arent doing video, then why are you using such a big video card? They make motherboards with very good integrated graphics on the AMD/ATI side as well as some nice integrated Nvidia southbridges too. You wont be playing Doom in the car, so why not go integrated?!

    I would also hot glue that card down or else it will rattle loose over time shorting out your pci/agp slots...

    I'm using that vidcard and mainboard because that is what I had...I spent money elsewhere instead of buying a new mainboard.
    That vid card is only 40 watts or so...and that's when running full-on 3D acceleration...it's not a 8800GTX by any stretch.
    The PC also run's Vista, so I can enable the Aero desktop theme and also run Media Center with all the eye candy with that vid card...
    Not to mention DVD playback is hardware supported with the 9700 Pro...

    Besides, how am I gonna liquid cool an integrated vid card?

    killer install dude

    but why 2 Xonar Sound cards? Mind sharing your audio setup?

    Is it 3 way, 2 way ? or with subs? Or are you doin some multi zone front / rear audio splits.

    How are you handling the audio processing? Wouldn't Optical to a processor be easier, and not to mention cheaper?

    It's really a rad install, but im wondering (besides the obvious bling-geek factor of a water cooled car pc)
    Why you didn't choose a board like the Jetway NC62k, which can run something like the AMD 4850e with the m2-atx easy, which, would support vista aero with ease, without the need for extreme water cooling.

    From experience, the car pc hobby is a friggin addictive and intensive one, with numerous testing, re testing and switching of components.

    A built in, PITA to remove install will earn you loads of neck aches and strained eyes trying to troubleshoot something seemingly minor.

    Just my two cents...
