    Officially 16 GB via one slot, but community reports suggest dual-slot versions may support 32–64 GB.
  • Q: Can it run Linux and Plex server?
    Yes—users have successfully used it as a low-power Plex server; fanless nature and TPM support enhance reliability.
  • Q: Any overheating issues?
    Not reported—passive cooling handles 6 W TDP CPUs effectively, though placement in tight spaces is advised.

 Community Insights

"I like the fact that it's from a major brand and it has 2 NICs... Great little computer. It will either replace my current unraid PC or be used for emulation."

Another notes Fanless Tech confirms the ADL‑S runs silently compared to the regular ADL model with a fan.
