The definition of a "pro" computer is simply one that has the latest technology. And new technology is always big and hot and noisy before it is small and cool and quiet. So a pro chassis is necessarily large with lots of cooling.

Eh. I wouldn't say a pro computer necessarily has to have the latest technology. Gaming systems are more known for pushing the latest technology and higher performance processors. The definition of a "pro" computer is one that can handle professional level workflows, in any capacity, without too many compromises (hoops to jump through) to get your work done.

"Pro" in computers usually connotes the system can handle larger, more complex workflows than a "regular" system could - more memory, faster processors, more storage, etc. The idea that it has to be easily "expandable" is just leftover geek-speak from an era when just about all computers were "expandable." It comes from the fact that most casual computer owners rarely ever expanded or upgraded their systems, while "professionals" (pros, gamers, and hobbyists) usually did.
