Rock64 - Use as desktop

[tbalci]

Hi,

I am considering setting up Rock64 as a desktop system. I am comfortable with Linux, so the flavor really does not matter.

What I want to achieve is a complete desktop solution with Rock64 + Wifi + 64 GB eMMC.
 
My questions are:

• Do the Linux images released contain all the drivers needed? In other words, will I be able to assemble the system, flash the eMMC, boot and everything just works? 
  
• Does the distros available for download use their official repositories (Ubuntu, Debian, Arch... ) or do we need to use ayufan's repositories?
  
• Can we enable distro's official ARM repository and be able to download software, or are we restricted to Pine64 repositories?
  
• I see the A/V jack on the board. Is this for a general purpose 3.5 mm sound jack?
  

To be absolutely honest, I want to be a bit comfortable - I am fine with Linux, terminal and troubleshooting, but not so far up to drivers or other low level tasks. So I'd like to have a working system as a baseline to start with.

These are the questions that are holding me back from ordering, really.

Thank you for your replies!

Regards
