hi, i am planing a car computer system in this comming summer.

the main brain , i have
p4 1.5g /256ram/external video card /ATX
celeron 1.8 /256ram /internal vga output/micro ATX
p3 650 laptop /184ram/dvd/10gb hd

personally , i will go for the celeron1.8 for its compactness and performance.

if so, what kinda of power supply should i get? my budgut is less than $100. any DIY PSU will fit my computer and the budgut?

also, waht is the best value 7in vga lcd on the market? touch screen is not needed.

thanks for any inputs
