Exteriors get cleaned along with everything else, but it's not much of maintenance because it's all aesthetics and not functionality. I don't worry too much about interiors though. Occassionally I vacuum some dust from inside of my PC, but I don't really touch anything else. Opening a PC is quite easy but can't really say the same about consoles and other devices. And yes, I know vacuuming the insides is a horrible idea. I've been lucky with it so far and I'm pretty careful with it, so I continue doing it. Eventually something's probably going to break though.
