Help for a newbie choosing the right box

I’m looking to get a Kodi box and have been doing a fair bit of research. The more I look, the more confused I get. The best source so far has been the “Star Here” post in this form by “wrxasty”. Based on this post and other research, I’m about ready to purchase a Minix U9 box.

I’ve been unable to find a thorough user manual or full operational instructions to confirm that it truly meets my needs. Can some kind person offer advice on this issue?

Here are my needs:

  1. Initially, I’m looking to replace my discontinued WDTV live. I’d like the Minix to play my stored media files from 1 or 2 HDDs connected to the Minix. (my media is a variety of all video formats as well as MP3s)
  2. I’d like to be able to see the HDDs connected to the Minix on my PC local network so that files could be transferred to and from the unit.
  3. I’d like to be able to play media stored on my PC via the Minix
  4. I’d like to be able to stream US broadcast TV on the Minix
  5. At some time, I’d like to be able to play H265 and ATMOS video on the Minix
  6. In the future, I’d probably like to subscribe to and play Netflix
  7. I’d like it to be able to play 4K

As an aside, I see on the Minix site that some of their boxes run Windows 10 and others run Andriod. I find the Windows alternative appealing since I’m likely to be able to access a Windows based Nimix on my network just like another PC. Would an Windows box be better for me?

I see that some U9s available for sale come with the MINIX NEO K1 Wireless Keyboard Remote Control. That seems a little bulky for everyday use. If I get the normal remote, does the U9 have the ability to connect to my existing Bluetooth keyboard?

Does the Minix U9 meet these requirements? If not can anyone provide a recommendation.
