ASUS Mainboard ROG Crosshair VIII Impact - ATX - Socket AM4 - AMD X570

Impact's unusual form factor is a deliberate choice. Many mini-ITX cases ship with enough space for a dual-slot graphics card, meaning there's typically unused space below the bottom PCIe slot - space that could be utilized to mount more components or enable additional features. Being marginally taller than mini-ITX allows Impact to exploit this unused space, allowing ROG engineers to squeeze in features while still fitting a large proportion of mini-ITX PC cases.
