Mine does that too.  I think it's to be expected since the power
supply is right under there; according to some early information on
the power supply, the first machines (including the present ones,
I presume) used a conventional, non-switching power supply due to
some problem Apple had with getting the switching power supply out
in time.  If so, that would explain part of it, since I think it would tend
to get hotter than a switching power supply would.  In any case,
there's a note on page 135 of the plain User's Manual in the section
entitled "keeping it in good shape/main unit" which says "The top
of the main unit will feel warm to the touch (about 85 - 90 degrees
F.) after it's been on for awhile."

Right now as I write this, mine has a temperature of 102 degrees
F. measured by putting a desktop thermometer face down on top of
the left vent until it became stable.  That's with a room temp-
erature of about 78 degrees.
