At 24/7 you are not temperature cycling your computer which should
extend its life.

Not sure what your implying here. Tempaerature cycling is exactly what
will SHORTEN an electronics device's life. It's better to run electronics
in a steady state environment, within thier specs.

Electro-mechanical devices may last longer due to thier mechanical
nature, but in general, a great deal of stress occurs during the temperature
cycling phases, and the in-rush of currents that occur when a device
powers up.

Unless there's something you're aware of, that I'm not.
