Me too.

Me too, I started with a 1040, which I ran all the time.  But it was
not out of fear of blowing the power supply.  I just didn't like to
wait for it to boot up, and I hated having to set the clock.

I had no problem.  I think that the heat transfer is good enough in that
machine, but can not say anything about what happens if you load it up
with extra chips.  I noticed that the underside of the desk top warms
up, after the machine was on a couple of days. 

I recommend that you keep the top vents clear of papers, floppies, etc. 
Some folks store their floppies on top of the vents; I try not to for
two reasons: first, the heat, second, proximity to the power supply, at
the left side of the unit, I think, whose magnetic flux could cause
deterioration of the information on the diskettes. 

Now i have a Mega ST and my only complaint is the noise of the fan.
