Carputer

[Anduinlight]

Alright I know there are one or two of you guys who can answer this for me,

I was thinking about building a carputer (you know a computer that is built into your car) and I just had a couple questions about doing it
-do you think it would be alright to use desktop hardware (like cpus motherboards, graphics cards ect.) for the components?
-as far as like hardrives, are they fairly shock proof or resistant? or is their a peticular brand, or would laptop compnents really be better?
-now I plan on putting the main box (tower) in the back, and a monitor in the front (probably like a 7" video touch screen with a couple of video ins or... a really small lcd 12" computer monitor) when i'm pipin all the cables, and such to the front, is there a good way to insulate for "noise" (for all you car audio people you know what i mean) for those who don't it's when signal is picked up along the lines from your alternator, now as far as audio is concerned all you get is some nasty, high pitched squealing, from your speakers. However when it comess to data travling on lines it would get corrupted and be unusable. So is there a good way to insulate for that?

- and lastly the most important question: Is there actually a compant of some sorts who actually does this type of thing?? that I could also ask, or even get parts from??

-or if this is just a dumb idea you can tell me that too
thanks
