Can somebody recommend media box (such old WD live, Mede8er, Iamm...) based on Linux OS that support 4K.

I don`t want andoid box. I had 3 android and had so much issues and problems with it, stuttering on playback over LAN from my PC. I don`t need it for playin games.
LAN is must have. I have wired LAN all over my house. I don`t belive in wireless for 4K 100mb/s videos.

Dune media players aorund 500€ is too much for me but I see they are on some android OS ad well.

any suggestion?
