https://www.osnews.com/story/131144/inside-intels-ghost-canyon-nuc-the-incredibly-small-modular-desktop-pc/ >This is my problem please someone make us PICMG 1.3 cpu half board using AM4 with a decent heat-sink(should be doable 2 slot width considering how much heat GPU make).. With a nice sanely wired up PICMG 1.3 half back plane(half means no old PCI slots but is a pcie x16+ x8 from cpu card ie 24 pcie lanes to play with). With a decent flex ATX powersupply. Something like this will be the same size on desk/floor as the intel NUC.
