Plex Server, NAS vs Nvidia Shield Pro

[robj20]

Hope this is the right section.
Is the Nvidia Shield a good option for a plex server or is it better to use a NAS im looking at the Qnap 453D has a celeran J4125 CPU.

After the wife saying she wants simplicity i got the NAS, plenty fast enough, i can overload it, had every firestick and every phone streaming and it was doing it with ease.
Bonus is it has Pi-hole built in so a quick DNS redirect and thats working as well.
Means going forward i only need the cheaper none Pro shields to replace the really old slow firesticks.
