that the majority of those with that type of cycle, do it themselves.

They only have a tech when it's something wrong, otherwise self maintained, and reasonably well done. 3D work, animations etc need decently running systems, so they quickly learn how to avoid many issues.
heck, they themselves research hardware specs like a tech BEFORE buying a new system or doing a hardware upgrade. Though you won't talk them out of a particular decision unless you are offering a better performance option.
