I've been saying this for a while now, but the ATX standard needs a complete modern redesign centered around the GPU, instead of the CPU like in the 90's, when that component was the most important and energy intensive one.

But since Intel is the original designer and contribuitor of the ATX standard, I doubt they're looking forward to give up the throne in the system to Nvidia/AMD till they gain any majority share in the GPU market which won't happen in my lifetime.

The ATX standard is far too long in the tooth already and you can see various people doing their own hack jobs at home, while case and motherboard manufacturers try to innovate around it without Intel, going in their own directions with non-standard deviations and hacks, meaning components are expensive due to lack of economies of scale and cross-compatibility is a mess.

I guess the lack of interest in modernizing the ATX standard also stems form the fact that PC sales have been on the decline for over a decade(pandemic excluded) due to the rise of mobile use, with tower PCs seeing an even bigger decline as most people and companies who still need PCs use laptops now, meaning ATX style PCs have made a 360 turn back to being a rarity for hackers/geeks/gamers instead of something everyone had to have in their homes and offices.

But what I personally want today is not another quirky square box occupying space on my desk/floor, but a stealth desk PC like this one (watch the video it's worth it): https://www.youtube.com/watch?v=UQ6ueTe8KQM
