https://www.supermicro.com/en/products/motherboard/A1SRM-2758F the A1SRM boards look really promising! Some of these atom chips are 7-12w TDP which is basically an nvme m2 drive at this point. Theres a variety of these available for the various atom C series processors too. Now I just need to see if theres support for intel i354 in *BSD The secondary market for these are great too. Under 100 bucks for the board and memory is also really cheap because nobody cares about DDR3 ECC. No m2 slots but plenty of sata ports. #homelab
