It is a good conductor of heat, it is cheap and light
Yes, today's computers use transistors and microprocessors. Smaller transistors subset the amount of RAM that is local to the CPU at any given moment.
Aluminium has a low density and is not corroded.
You can make rings with it or you can cut out a photo frame out of cardboard and cover it in foil its so cool and pretty.

cooling
I will assume you mean "transistors". Compared to their predecessors (vacuum tubes), transistors:* Are faster * Use less current * Use less space Note that all of these advantages get even more pronounced in the case of integrated circuits (which also contain transistors).
If the integrated circuit in some kind of device has 5,000 transistors on it, then before integrated circuits were available, the same function might have been performed by 100 individual transistors. And before transistors were available, the same function might have been performed by 30 vacuum tubes, a fan and air system to keep them cool, and a large power system to operate the tubes and the cooler.
Transistors are not normally connected to dc motors, but it is possible to use transistors in a speed-control mechanism for a motor.
UNIVAC I
We use gold and transistors.
