Great build! Im gonna probably build the exact same thing....do you know which boards do the 4K@60hz and able to do HDR or do you have to get the GPU for HDR ability?
Also i love the idea of 2 GB Ethernet ports. Could I connect one port directly to my Synology Nas 216play to access the files on my raid providing great access speeds to my 4K library and use the other ethernet port to connect to my router to connect to the internet so I can download etc...?
How are you using these ports?
Thank you from the UK
