Hey, i just realized by looking around, that there has been for some time that kind of board around. It was the mid 2000s when even AMD tried that format. And now the drumroll ... it's standard DTX format. That is just simply an even shorter Version of mATX.
But i'm even more disappointed, because to be honest, most of us PC builders we dont use all the features of ATX. Sure, years ago we did, but now mostt of us only use 2-4 memorysticks, 1-2 Sata, 1-2 M.2 and the one PCIe for the GPU. So for what are we buying those giant boards, i dont even use the full potential of my mATX because most cases for that formfactor dont even have room for 6 SATA Drives.
