Hi everyone,

i am so glad to have found this forum as i myself have been toying with the idea of installing a PC into my car. I'm sure all of you are more experienced than me, therefore please give me any feed back or suggestions you have on my 1st design.

Running off my old P4 1.8GHz, i'm going to do the following:

CPU:
-place mobo along with sound and video card below my driver's seat.
-purhcase an inverter and place it in the boot
-wire cigarette lighter to the inverter
-wire inverter to the mobo's PSU underneath my seat
-4xUSB ports will be fixed in an empty space above cigarette lighter

LCD - built in speakers
-LCD monitor sits on a custom stand which base is permanently fixed
-stand will be allow me to move the LCD around, like your table lamps
-DVI cable, audio cable and power cable runs inside the stand frame
-stand sits in front of the gear, therefore little wiring is needed from mobo

Keyboard/Mouse
-USB mouse and keyboard
-thinking of also using a USB gamepad

the problems i'm facing:
1. if i use my old PSU to power my mobo,wat do i use to power the LCD?
2. will the car's 12V battery be enough to power my setup?
3. placing the mobo underneath my seat with no casing, is it bad?
4. what is the minimum inverter spec do i need for this setup?
5. without any extra cooling,will my mobo or inverter overheat?

i really hope you guys can help me as not many people in Malaysia have done this before, that's why it's a new project for everyone here.

please offer me some advice. Thanks alot guys!

Hi Isis,
I'm not so expert, but I'll try to give you a hand...

-I personally don't like inverters: you can use an ATX dc-dc converter, so you don't have the 8-14V->130/220V->ATX(+-12V,+-5V) conversion. Just 8-14V-ATX! It means less interference (and heat?) in your system.
-I most cases LCD are DC driven, and the ac-dc converter are external. If it's your case, you can search for a dc-dc converter wich meets the power requirements of your LCD...

DC converters, anyway, are more expensive than inverter...

-I think casing the pc is better than leave it uncovered, for meccanical and electrostatic issues...

Anyway, some guys out there uses the inverter-normal pc solution, check out www.mp3car.com

I'm going to use this configuration instead:
-second-hand Epia-M9000, 512MB RAM (150EUR)
-LCD 7" Lilliput with Touchscreen (230EUR)
-PW70A dc-dc converter for epia-M (35EUR)
-second-hand DVD-ROM slim (50EUR)
-homemade case
-some other stuff like a 4x20LCD and IDE-CF...

This system is less power-consuming and more compact!!!

Instead of pw70A, I'm going to buy an M1-ATX dc-dc converter, with has a 12V voltage regulator, so my pc doesn't shut down when I'm cranking my car, 'cause pw70a needs regulated 12V in Mad Crying or Very sad
