Big update guys...!
I have completed the computer and its box. I am waiting on a few more parts and then its getting installed into the car.
The motherboard is pulled from a Dell Optiplex 150 (I picked it out of the trash at school). It has a reflashed BIOS to get rid of all the school branding and passwords (and to add B0 Processor Stepping for the PIII i put in)
Specs:
Intel Pentium III 933MHz CPU
256MB PC100 SDRAM
40GB Fujitsu Laptop Harddrive (with Laptop to Standard IDE adapter)
M1-ATX PSU
Modified VIA USB 2.0 PCI Card
Thats whats housed in the custom home made plexiglas box.
Outside of this there will be the following:
Hollux USB GPS Mouse
Pioneer Slot-Load Dual Layer DVD Burner/Reader
USB Wi-Fi 802.11g
RF Wireless Keyboard and Mouse
USB adapter for the DVD Drive
8" 4:3 (800x600) LCD Panel with TV Tuner and Touchscreen
I am still waiting for the LCD and the Drive adapter to come in the mail and as soon as they do the pc is going into the car.
Below are some pictures of the parts.
