Looking at a Porsche 911 997 gen2 turbo, PCCB or not?!

So I have got the funds to start looking at a 911 997 gen2 turbo. Just wondering if PCCB are desirable in terms of resale and if I would have big bills if I bought a car with them on?!

Is this good value? I know a bit high in the miles but looks a nice spec
