I'm looking for something less than 3 hours. Soon after I moved my myth 
computer into a cabinet I cranked up a mencoder job to reduce the size 
of an HD recording. Woke up the following morning and found the computer 
off so I turned it back on and looked at the system log. Turns out the 
CPU temp rose to 75C and Linux did an orderly shutdown. I have some air 
flow issues to deal with and I'm mildy surprised a subsystem of Linux 
was smart enough to halt the computer.
