Sorry I'm not that active on this forum. I'm quite busy at the moment and do not have much time for this power supplies.
Also I do not have that many left.

1) Your case Silverstone ML03B is not that different from the one I have. Did you seen the way I mounted my PSU's on the case. I use a dual PSU even if I do not actually needed.
The 4 pin mini din in the link is the same type as the one on the ATX board
There are two way to connect power to the PSU see

I will also include for you two 4pin mini-DIN extension cables you can cut them or use them as you like.
I guess you already seen this

and this

In your case the PSU's will probably need to be horizontal and not vertical.

2) ? "Fancy mounting pins" not sure what are you referring to I used #4 bolts and nuts as you see in the photo above it works quite good.


PS: sorry for the two power supply setup I was thinking I'm talking with another person.

Sorry I did not see your post last time I logged in.
I will send you the PSU's today.
PSU delivers quite clean power since it has a lot of filtering and was specialty design to have as little interferences as possible.
But the rest of your components are consumer components and a Fan and even the HDD can be actually more cleaner than the motherboard.
The main reason for that is that you have high power DC-DC converter on the main board one is for CPU 12V down to 1.xx Volt then there is the one for RAM also under 2V and probably from 12V line.

Is not necessary to power motherboard and CPU from separate power supply unless you want to use a dedicated video card.
But with your setup a single power supply can deliver easily power to the entire PC.
Not sure what you can power with a separate power supply in order to get a "cleaner" power.
The most important is that the sound card is shilled and has his own filter and some quality sound card have that.
Also not sure if your "music server" is just a server so your music is transmitted by LAN or WLAN to other devices or computer or is more of a media center that will play the music directly whit his own sound card. In first case the "dirty" power supply will have zero influence.

Thanks for answering so quickly.

You are right, "music server" is not an adequate description; I will be playing music directly (digitally) from the PC to an external DAC. Probably via USB or AES/EBU outputs.

I will have to do my experimenting, but the argument I've seen (and I might as well try to benefit from others efforts and legwork), is that there are elements such as the mechanical motors of fans and hard drives that pollute the power and thus contribute to jitter in the digital audio signal , which then must be dealt with with superior products downstream. If I'm able to avert such issues within the PC case, I don't see how it can hurt.

At the least, I have addressed the power quality and silence issues! My fans are there only as protection, and will only kick on at prescribed heat thresholds.

Hey. You actually already answered my questions through my direct emails to you, but thanks for taking the time that you don't have to respond over here too!

Everything's mounted, connected, and running perfectly at the moment.

FYI, these were the fancy mounting pins I was talking about:
