    it would have no negative effects, at lower temperatures, look at tomshardware.com, someone cooled their proccesor with liquid nitrogen.
    If you worried your system will get damaged by the cold, it wont. If you have a lcd though, it can freeze and crack from the cold

    That's not exactly correct Mr. Wilco.

    Mechanical devices such as hardrives will likely have problems at that temperature.
    Best to warm them up first.

    Condensation can build, but this is in rare cases (well rare climate conditions).

    There is also the issue of fluid bearing hard drives in the extreme cold.

    Also true that LCD can crack, but they also take a long time to wamr up (obviously)

    I've noticed overvoltage in some (two cheap) power supplies. One caused a system to crash (vCore changed about .1v)

    If you're into overclocking, -10c can be good

    Well, there was a topic going on earlier about cold weather and carputers. No one has really got this tested as far as I know.

    As far as Cpu, Mobo, video card, and such you shouldn't have much issues. I read in some places that the LCD will take a couple minutes to 'warm-up' before lighting up.

    The second potential and most probable issue is the hard drive. Rated to work at 5Deg C And up, this becomes a major issue, especially the new FDB Motors. Guess time will tell as we will inevitable get reports from people soon who live in the colder climates.

    How about -35c ???
    Now comp started in -5c and warming about 5-10 min...
    I have LCD bult-in car... In -35c they not crack but show very slowly ))
    I think HDD may damage in -15c and below...
    One-two month later i will testes carputer with temp below -20c...

    Just i am interesting, may be somebody already use carputer in belower temp's...

    speaking of condenstaion building at lower temps, why doesnt this short out, http://www.tomshardware.com/cpu/20031230/
    and if hard drives, get to be that big of a problem, you could always just get a usb, and bring it in the house with you

    The reason the condensation from this experiment didn't effect the mobo or surrounding electronics is because the temperatures were so low it prevented the ice crystals from melting. Ice, by nature is not harmful to electronics, however, when it melts it is quite hazardous. If you have ice crystals on any electronics, do not turn it on, the heat disapated from it alone will melt it immediately. Liquid nitrogen on the other hand is so cold it prevents it from melting.
    WTF?!? You did what? With who? Why?
    Current Carputer... 20GB iPod, I am working on an upgrade though!

    just one point people water is non conductive ( i learnt this at a-level physics and GCSE chemistry for those in the uk) the thing that causes the water to conduct the electricity is stuff in it such as salts that cause it to be impure and hence conduct. i thought it was fairly common knowledge that some of the worlds SUPER computers were cooled by placing them in huge vats of distilled water. so if you were to unplug the mobo, wash it down with distilled water to be fairly sure there were no impurities, and place it in a container ( againg perfectly clean) full of distilled water and plug in and run you should get a super cooled computer.

    in the real world of home pc owners it is completely impractical and too much hastle to do this mostly because u cant ever easily get rid of enuf of the impurities and so risk the gear. obviously also you would not want to put the mains in the water ( just in case there are impurities that conduct)

    there is one other problem caused if you put terminals in water it will electrolise so you will end up with an excess of hydrogen and oxygen in the atmosphere around the water ( so dont light up lol )

    not too bad for a noob
