Is it bad to leave my Powerbook on all the time, but leave the lid open so it does not enter sleep mode? I've noticed that when I do this it gets really warm. Is that bad for it?

It's not bad to leave your PB on all the time. Just make sure it is well ventilated. Hot parts don't usually last as long as cooler ones.

There are some ongoing threads that can relate to this one, I linked one here : Keep on or turn off?

I'd at least be sure to have the hard drive set to sleep when idle. The tech notes on most laptop hard disks do mention that they are not intended to be run 24/7. Also, you do have the screen set to sleep? - just that the backlight is the one component that is degrading from the moment it's first used, so I'd think you want to maximize it's potential life span.

If you have the screen and disk set to sleep, and processor speed set to automatic (and assuming the laptop is in a well ventilated area), I wouldn't think it should get overly warm, even with background tasks crunching. Even so, every Mac machine for years now has pretty sophisticated thermal overload/shutdown protection, so it cannot literally overheat.

I do this all the time--the rig can totally handle it. Make sure it's reasonably ventilated, and let the screen backlight go off to save the lamp.
