I recommend this pc. Since this computer takes dc 18v, you don't need to purchase an expensive external dc power supply. Get a laptop car charger and it might even survive the crank. I have HP e-pc(just like this computer but little bigger and cheaper) and couldn't be happier. For the price of Opus, I was able to buy the whole pc plus $25 car adaptor being able to survive the crank. Down side is limited expendability.
