On the Asus board with an N100 you can install an adapter to 6 SATA ports in the minipcie port like this: https://es.aliexpress.com/i/1005005068881876.html
and a network adapter on the pcie port like this: https://www.amazon.es/Adaptado…Controlador/dp/B0BNHWZBCC
or dual like this: https://www.amazon.es/Adaptado…controlador/dp/B0CBX9MNXX
Yep, that would be the only possibility for my use case. I just do believe that this little board might then consume much more power. Momentarily I am sorting things out.. and maybe something entirely different comes up my way - I even consider an ATX Board that can do low while the nas is idling even if the build itself would be a significantly bigger than my old machine.
