Does this hardware to run LE exist?

Hi,

I’m running LE on a Chromebox (CN62) and although I am satisfied with th eoverall experience, I am looking to upgrade in order to have 4K HEVC 10bit support.

The box is connected to a Samsung UE65KS8000 and a Pioneer receiver (supports HDMI 2.2, HD audio formats)

Here are the specifications I would like to have and that I can’t seem to find in any available box:
-LibreElec support
-23.976/24Hz support
-Gigabit ethernet
-HD audio passthrough
-4K 10bit HEVC hardware decoding

From what I’ve read here, Nvidia Shield and Kaby Lake NUCs have some problems with HD audio passthrough, Vero 4K has a 100Mbit ethernet port, other boxes either struggle with 4K HEVC or don’t support it at all.

So my question is, does this hardware exist (for a reasonable price, i.e. under 500€/$) ?
