Cost of a microcontroller - is it very important?

A newbie here.
After reading a small portion of the discussion, this question comes up in
my head, is the cost of microcontroller a very important issue in terms of
picking the right one? How much a microcontroller CAN contribute to a
whole product?

Or is it the functionality, speed, power consumption and development
toolchain userfriendly-ness more important in the decision?

I am thinking about using Cortex M3 for my server cabinet temp controller
project, is it a bad choice in any context?

Many thanks in advance

Henry
