Yes, yes and yes ! Exactly !More or less exactly this.
Just a premium looking NR200 style do-it-all type case that had improved GPU compatibility, offers an inverted layout for lower GPU temps and adds top 140mm fan support while maintaining side bracket 140mm fan / 280mm aio support and offering enough width for 155mm air coolers or AIO's with thicker combined rad / fan / pump height like the AF3 series.
Thicc AIO setup? No problem. Peerless Assassin? No problem. Want to install 4x A14x25 G2's because... Noctua? No problem.
It wouldn't be THAT much bigger than it is. It would be the perfect small case. No restrictions basically while being half the litres of a normal Mid-Tower.
