The chasis is pretty scuffed up -- I bought it this way (I'm not the original owner). Does not affect functionality though. I kinda like it, actually -- it adds to the whole "sleeper" thing ;) The missing screw pictured in the bottom right of the display bezel has since been replaced.
Currently running Arch Linux (btw) but I'll happily install whichever Linux distro or version of Windows you'd like.
