I got this to mount behind my flat screen TV to stream content off the internet.  I hooked it up to two USB cables with wireless dongles for a keyboard and mouse, and can now sit across the room with them and control the computer which is connected to my HDMI Arc outlet.  Audio is good, picture quality and frame rates excellent.  VERY high UHD.  I had to knock it down to 1080 so that I could read the print on the screen.  It came with a thumb drive with a complete Windows 10 professional x64 installer and installation was a breeze, although had to go through the  usual removal of bloatware and blocking Microsoft from upgrading it to Windows 11 which I don't want.  A little bit of fan noise is worrisome, but after all it took to set it up, if it fails, I'll fix the fan myself.  Overall I'm very happy with it.
