"EVGA X299 FTW - K (142-SX-E297) - 6 - Motherboard Specifications Size: EATX form-factor of 12 inches x 10.375 inches (304.8x276.7mm)"
Is the Size given (Height x Width) or (Width x Height)?
I bought a Corsair Crystal Series 570X RGB ATX Mid-Tower Case that does ATX (Up to 272mm) Wide.... 4mm is small enough to the point i doubt it will matter, but i want to make sure im reading the sizing correctly
