If you are looking high end cases they are out there, just hidden.

Such as,

Dune Pro: https://www.dunecase.com/ InWin lines: https://www.in-win.com/en/gaming-chassis/z-tower/ Lian Li, Cases that are desks, and other high end designs: http://www.lian-li.com/

If you have money, you will find people looking to sell you high end cases.

I personally use Fractal Design cases, they look good, made of thick steel, and are cheap enough I can replace them more often without feeling bad.
