These look cool. I am intrigued by the USB ports.

 

Are the two USB (Clean) ones those from the SOTM card?

 

Are the two other USB ports not clean in any way? If so, what would they be used for, offline transfer of files via USB sticks or something else?

 

Additionally, if you were forced to use an external USB HDD drive, would you also use one of the Clean USB Ports?

 

Kudos on choosing the low voltage memory - that should help tremendously with ground plane noise and RFI/EMI.

 

Overall, looks like a great server to use.

 

The two "Clean USB" ports are the direct outputs of a new SOtM card that was designed for Chris for this project. The new SOtM card is mounted to the custom back panel. You would connect your USB audio device to one of the two "Clean USB" ports and any external USB drives to the motherboard's USB ports.

Can we have a picture of this new USB card? I am curious how this card is connected to the NUC mini-PCIe slot. Or is there a cable part between the mini-PCIe and the card in the extra bay of the case?

 

A SOtM SATA filter provides clean power to the SOtM card. The SOtM card then connects to the motherboard via USB. You can also power the SOtM card via the external power connector that bypasses the internal power with something like the SOtM batter supply or SOtM linear supply.

Chris, the SotM USB card you used; is it the tX-USBhubIn mentioned on SotM's website?

 

Yes. The tX-USBhubIn was commissioned from SOtM specifically for this project. Also, this week Andrew received the first batch of the boards and he now has all the components to build the Maroubra server.
