Hi everyone. I just find this site 2days ago. I been looking to do something like this for almost 3yrs now. I'm a computer tech so building a pc is no problem. The big qustion I have is, I have a real nice system in my car....how would I go about hooking the pc up to my sound system. This the screen i'm thinking of getting. (Lilliput 7" VGA Touchscreen 619GL-70NP) Or could someone point me to the right place.
