There used to be so called PIO motherboards from China. These were slightly larger than ITX and the PCIe connector was 90 degrees rotated so the video card was planar with the motherboard. https://imgur.com/a/ve1T0dE https://imgur.com/a/ve1T0dE And if we are to reform our computer chassis anyways, we could move the PSU to straddle the motherboard and the video card and even have the VRM inside. High amperage "comb" connectors exist and VRM daughtercard motherboards existed https://c1.neweggimages.com/NeweggImage/productimage/13-131-932-02.jpg https://c1.neweggimages.com/NeweggImage/productimage/13-131-... Change the form factor so two 120mm fans fit, one in front, one in the back. So you would have three 120mm front-to-back tunnels: one for the video card, one for the PSU, one for the CPU.
