Aoostar n100 2 Bay nas is what I'm currently thinking about. Or the same device but rebadged.
Pros: n100 for quicksync.
2 bays of HDD for media storage.
Low power at idle.
Cheap for a box with all relevant codecs + sata storage.
High WAF compared to other HTPCs
Cons: Unknown brand for build quality and bios updates.
General Chinese security anxieties.
Idle power, while low, is higher than other n100 options.
Fan isn't pwm.
Personally don't like the aesthetics.
