Because carbon fiber sheets aren't cheap compared to steel and aluminum. The production process(applying resin, autoclaving, fine detailing and paint) is way more time consuming than bending, stamping and pressing metal to shapes that they want. For $200, you could only afford the side panels.
not really.. thats only if they needed specially molded shapes.
Were not wrapping indy cars, or automotive.
If they made boxes out of carbon fiber it would still sell.
Basic shapes or a U shape out of carbon fiber is not terribly expensive.
Well, considering how most of these cases are from china... in china i guess carbon fiber is more expensive...
Anyhow once 3d printing takes off, say bye bye to case vendors..
They NEVER listen... and its always down to you yourself to either mod, or fix.
So i'll just 3d print my own case.
carbon fiber is also an insulator.
and since when did people use cases as a heat sink?
Unless we talking about passive case designs where the side panel is the heat sink.
My MM with powder coat paint job is also very insulating.
Yet the temps inside the case and outside dont variate more then 1-2C degree's...
