I am moving up from my laptop based system to a more powerful pc system.
MoBo/CPU: 1.6Ghz dual core biostar atom 330(mITX)
PSU: M2-atx,
RAM: 2GB
HDD: 320GB storage and 40gb for OS and programs
7" liliput screen
2 headrest monitors
2 boot monitors (dont ask!!!

lol)
sound goes is into 'original' HU850 volvo head unit via a USA-SPEC ipod adaptor
GPS module
DVD/CD-RW in 'orignal' head unit to make it look oem.
making my own case for it as i want it to be hidden behind one of the rear panels.
