Ready For Digital Source...Computer?


I have speakers and amplification all figured out, now I need a source. No vinyl and not concerned with CD's at this point.
Only steaming online. No Roon either, been there, done that. 

Honestly, (because I need a new computer anyway) I would really like to use a computer to play Spotify (hopefully CD-quality soon), Tidal, Qobuz, etc. but most say a computer is too "Noisy" to use for this purpose. Although, I have heard there are ways around this.

Rather than having to purchase a dedicated music server, does anyone know how to set up a computer as a high-quality music server? I can't really seem to find anything online.

Thanks

auxinput - the only piece of gear I have left after the great sell-off is a 100W HDPlex linear power supply, which I bought second-hand.

It has 4 taps: 5V, 12V, 19V (using for my old Nucleus), and a variable outlet.

It never got hot when I was using all the outputs at once, but it is rather old, so maybe I should be upgrading it?

@high-amp   It would be very helpful if you clarify (read: lock in) your choice of path. It has wavered since your original post.

Members will be able to help you with better recommendations and approaches, once you clarify and select the path.

Re. the original (100W??) HDPlex: it's a good starting point. The Keces P8 is at another level.

No need to apologize. You are likely clear on this, but I'm not and perhaps others  are not as well.

Times on my side at the moment so, sooner or later I’ll figure it out

For example: Figure what out? 

If you have, restating what you've figured out in this thread or starting a new one would, I believe, offer focused insight from members.

It's a suggestion. If you feel you have already addressed it and stated so, I'm cool with that. All the best.
