Sometimes I wonder what the thought process behind the gaming aesthetic was. RGB (*if tunable) itself is fine and adds a nice opportunity for personalization, but are those tacky fonts, crystal-facet enclosures, and overall showiness just tasteless or do any gamers actually prefer that look?
Market segregation.
LED gamer builds uses to be the “premium” segment, but they figured out that all the kids who want a “Gaming PC” don’t care how loud it is or what the quality is like as long as it matches the “gamer” aesthetic.
Conversely, someone who cares about sound decibels and airflow as a primary concern is now part of a niche demographic, so they can charge you more.
