New dedicated computers and new case

[FelipeRolim]

Hello friends. I created this topic to share with you the photos of the new case I built for dedicated computers (the software is the same as always - Windows Server 2019 Datacenter Core Mode and JPLAY FEMTO). With more time, I will insert in the descriptions about the reasons that led me to adopt this new layout, as well as the sound that I have obtained with the last changes. Since there are so many photos, I created a shared folder to access and view.

Where did you get does atx power supplies from?

Why didn't you use any shielding?

The ATX adapter is the Mini-Box M4-ATX, which I prefer to use in conjunction with other elements to power the motherboards. In my experiments, I saw no advantage in using independent power sections for them, especially because I don't use M.2 SSD and because the processors have an independent 12v power path. Today, if I were to buy an ATX DC-DC adapter, I would buy the M3-ATX, as it is much smaller and fits directly on the motherboard. It's an application that I made after a lot of experimentation, but without any pretension of being correct in something. I only achieved a superior result with the DC-DC adapters together with a special model of power supply that I developed.

 

About the shielding, everything in this computer was thought and adjusted by finger to extract the best sound, to play in the most natural way possible. So inside it there's a combination of Jupiter Pure Silver wiring, Mundorf resistors, Mundorf and Elna capacitors and other things. Each part is meticulously designed for the sound that I aim for, including the wooden cabinet, the cushioning of some parts with cork, cotton and polymeric tape. Because of that, I decided to leave the experiments with grounding and shielding as the last step and, today, the only part of this computer that is effectively shielded is the AC cable from the transformer, which comes out of a Furutech FI-06 NCF inlet. Today, the computer is more or less as in the photo below, and there are two JCAT Net Card FEMTO still missing:

Hi Felipe, Here are some of my travels. 

I added HDPlex 400w ATX DC-DC adapters to both of my pcs and was amazed at the improvement. I previously used the nanoPSU. I shielded all internal power cables but didn't listen to see if I could hear a difference.

I built my own sata cable (for music hdd) with Kimber silver wire on the data lines, shielded twisted pairs, external shields, plus chassis ground connectors. This was an audible improvement.

I recommend ifi power x for the pcie cards. These give a nice benefit over lpsu in my system.
