I can say I have both the Extreme 12 (7204) and Extreme 14 (7404) on my campus and I’m running the 1.3.0-rcX series of FOG and both image properly. I have mine setup in legacy (bios) mode. They imaged with our standard Win7 build. You will need the newer kernels to support the intel nics as well as the NVMe disk (if that is in your model).
