[rescue] Indigo sans front cover

[rescue at sunhelp.org]

   I just scored an Indigo, but it doesn't have a front cover. It does,
however, have a sticker saying DO NOT OPERATE SYSTEM WITH FRONT COVER
REMOVED. All the pieces seem to be in place, and there's no sign that
the front cover was anything but a piece of plastic -- I don't see any
connections for fans, for example. What's the story? Is it a matter of
getting airflow over the disks? If so, it looks like a little clip-on fan
should take care of it.
