Ok, so if I get it right it should be like this.
1) You will need a USB-wire plus a 12V constant wire (mayby even a ground )
2) Need to take of a display from the (like said here) expensive appolo
3) their range of tft/lcd screens won't fit a carpc (like they sell 6,5 inch and 10,4 inch, nothing between)
Does it make any sense? And does it look usefull from this point of view?
