Well, right now I'm running a 3b1, 3.5Mb RAM, 67Mb HD in an
unairconditioned apartment in a two floor duplex.  There are trees
and such around the south and north sides, an apartment on the north side,
so sunlight only seeps in after about 1800hrs.  I have a window fan
that sucks air through the house at a pretty nice clip.  Avg interior
temp is probably around 90F or so.  About once every hour or so, the
fan kicks into what sounds like high gear for a few minutes.

I've had no overheating problems of any sort at all.  I keep 2 in open
on the right and left sides, 8 in in the front and back.  Airflow seems
to be good, but there's a lot of dust in this old house, so I have
to open it up and clean it out once every now and again... :-(

Hope this info was useful to someone.
