  I've experienced system problems whenever I put two hard drives on
the same lead ("bundle" of cables).  Sharing a lead with a CD-ROM or
floppy generally works fine; I haven't had a problem sharing a lead
with a fan, although others have cautioned against it.

  Yes, exactly.  If the power supply didn't come with them, you can
find cables about 2" long to convert a large connector to the small
one.

  I've used one or two weird devices that wanted a lead all to
themselves.  You don't mention any of them here, so it's probably not
an issue.
