Errr, not that I know ... In fact, I would be very suprised if that
were the case ...
nope, 2259 as system board and no speaker whatever next to the ram

Thought about "turning the cdrom outwards" (connector should allow
that) and cutting a hole in the chassis. but you are right, it might
not work at all ...

Sure, was just curious. I am also curious about the DIMM which is not
supposed to run in there ... I am also curious what other parts this
machine might now take which it was not prepared for :)
