Amazon has a deal on the Gigabyte Aero D for $ 289.99. Retail is $ 419.99 & this is the cheapest price since launch according to pcpartpicker. This "creator" board comes with quite a few premium IO options including:
* Dual Thunderbolt 4
* 10Gbe LAN
* PCIe 5.0 x16 (or x8/x8)
* DDR5 support
The board is listed on Amazon as ATX, however, Gigabyte’s website lists it as EATX since it is 1.5cm wider than a standard ATX motherboard. It still fits in some standard ATX cases though (fits fine in the NZXT 510 Flow).
