Not for me
The NAS of my dreams would occupy two real SATA slots, an energy efficient ARM SoC equipped with two SATA ports and 2.5GbE, the whole thing can be powered by a 12V/4A brick and will idle at below 3W with disks spun down.
I would love an arm cpu as powerfull as snapdragon 855 with 6 sata ports and a 2,5gbps port, but it doesn't exist right now.
Since I need plex, the average plex motherboard is not good enough for me.
