Building a Music Server

[davenrk]

I am trying to understand how to build a music server.

My final doubt is the following:
A PC motherboard contains VRMs, or buck converters (switch regulators), to convert 12V to 1.4V and 1V (and possibly other voltages?) for the CPU and various other chips.
Even if you change the ATX supply, you still have the switch regulators on the motherboard....
If you have low ripple power supply 10mV? but the MOBO regulators aren't so much "noisy" and produce a lot of ripple, the benefit of a LPS is canceled.
Or am I wrong?

So, my question is:
1) Do the MOBO VRM benefit anyway from a LPS?

2) How to choose a MOBO in order to have the best VRM and the lower ripple?

thanks

Very technical question. I think AudioPhileStyle might get more responses for this kind of queries IMHO.
