so far as naming your computers, the laptop I'm using at the moment is called en2229 boring name, but that's cause it's a work laptop.
my laptop at home (which I bought to leave in the front room in a house share so everyone could use the internet) is called porntop because it's for people to look up porn on.
so far as blowing smoke into your computer,
I don't think it'd have the same effect with laptops (and that's all I have now) my desktops haven't been switched on for ages.
Firstly I don't smoke in my room, because I don't want all my stuff to stink like smoke.
I had a friend in uni who smoked like a chimney, his ash tray was sat in front of his PC so there was always smoke blowing into his PC, this lead to everything inside being coated in a black sticky gunk, (the tar in the smoke).
(Cleaning that should have really put both of us off of smoking!)
