Hi,

Since r/NAS is not available and the Hardware@lemmy.ml could not provide that much help I am here again to ask stuff ;D.

My 10years old NAS quited work and I am looking for my opportunities. And since I am tinkering with my raspi and am generally interested in selfhosting stuff like jellyfin, joplin e.g. I decided to take the step to build my own Nas instead of buying another Synology device.

I would like to provide my needs but since I am not sure about it it is only a try… Moreover I cannot say where the journey will take me to^^

What I know:

  • 4 sata slots so I can use my actual drives and have the option to upgrade
  • Transcoding with jellyfin would be nice
  • having my own cloud storage is a long term aim
  • joplin server
  • maybe some terraria dedicated server could be cool also
  • low power usage and low noise are two criteria i would consider important since the energy prices only know one direction where I life
  • x64 architecture to use debian server or TrueNas Scale (I need to dive deeper into TrueNas before deciding)

My former favorite is this fanless board:
MITAC PD11EHI-J6413 MINI-ITX
Con:

  • I realised that the second M.2 slot does not supports M key SSDs but I planned to run the OS on an NVME… and since there is no PCIe the singel M.2 slot with M Key support is the only way to upgrade to 4 sata slots.

My actual favorite (but more expensive) choice seems to be:
MITAC PD10EHI-N6415
Con:

  • price (not so much of problem)

ECC compatibility feels unnecessary.

Is there anything that I have forgotten? Any better choices from european vendors? Ordering from america is not an option because it would take forever to arrive and the process to get it from the zoll is time consuming and would put taxes on top.

Thanks in advance 😊

    Thank you for your answer. the picoPSU is the next point that causes headaches. I have two questions about the pico.

    How to calculate how much energy is needed without knowing how much the board needs? My actual HDDs and planed parts are:

    • 2x 6TB WD Red WD60EFAX -> and I found the use 5.3W under load what means even with four of them they only need 21,2W
    • a NVME like the WD Blue SN570 with max consumption of 3,75W
    • a fan (maybe an be quiet! Silent Wings 4 PWM 120mm) for the case with round about 4W by max Speed sums up to 27,95W But the information about the power consumption for the board is missing.

    It seems like a 80 watts picoPSU should be sufficent. What I don’t understand is, how can I supply the power with this psu when it is a 24-pin ATX but the board needs only 4-Pin-ATX?

      I didn’t take a closer look at your board, sorry. The picoPSU is of course only possible if you need an ATX-Style power supply. If your board has an irregular connector, you’ll first have to find out what that is and where you can find an appropriate supply. It may be a “12 Volt Only” style connector, which would mean you only really need a fitting 12V power supply.

      Your max power calculations look fine.

        I have written a mail to the shop and asked them how to supply the power and if it is even possible with a picoPsu. If not, I guess I will take a Asrock instead. Using a regular ATX psu only for the one connector somehow feels not purposeful 🤷🏻‍♂️
