This rules out computers being made out of gas and plasma, how?

Maybe they would need to use a lot more energy.  The Sun's temperature is
around 15 million Kelvin, vs. room temperature being a few hundred Kelvin,
so maybe a bit less than 100,000 times as much as a computer on Earth.
Being literally inside the Sun, abundant energy would be available - more
than 100,000 times what is available on Earth.
