Qotom Q20332G9-S10 fanless “mini PC” features four 10 GbE and five 2.5GbE ports

Qotom Q20332G9-S10 is described as a fanless mini PC or somewhat more accurately as a router PC with four 10GbE SFP+ cages and five 2.5GbE RJ45 ports powered by an Intel Atom C3758R Denverton Refresh eight-core processor first introduced in 2020.

I would rather call it a network appliance than anything with “PC” in its name since the system only comes with VGA video output (e.g. no HDMI or DisplayPort output), no audio support, and Denverton server processors lack an internal GPU. The Qocom device supports up to 64GB DDR4 memory, up to two 2.5 SATA drives, and two M.2 NVMe SSDs, and comes with one extra M.2 socket for cellular connectivity and a few USB ports.

Qotom 10GbE router PC motherboard

As I completed the specs, I noticed the network appliance will be sold with either an Atom C3758R or the older Atom C3758, but in any case, it should not matter too much. The fanless router PC ships with a 12V/5A power supply, a power cord, and a VESA mount.

It’s available either as a barebone system or with RAM and an SSD pre-installed with an “unactivated Windows 10 in English for test”, and Qotom makes it clear they do not provide any Windows license.  ServerTheHome did a fairly detailed review of the system with Windows with benchmarks and a 4-bay NAS test, but I did not see any networking tests.

The main selling point of the Qotom Q20332G9-S10 is its price for a system with multiple 10GbE and 2.5GbE interfaces, as you’ll find it for around $300 on Amazon and Aliexpress in its barebone configuration, but you’ll also find variant with up to 64GB RAM and 2TB SSD. If you don’t need that many features, but still like 10GbE and 2.5GbE ports, the Gowin R86S mini PC is another option.

  1. I see Intel documents the integrated networking of C3758R as 4 x 10 GbE, and C3758 as 4×10/2.5/1 GbE.

    Do you know if 2.5Gb/1Gb ((H)SGMII) modules work fine in the 10Gbit SFP+ cages of this Q20332G9-S10 model?
    I intend to get one of these servers and use an FS GPON-ONU-34-20BI in it, do you know if it will work?

    Or should I go with the model with the older cpu model?
    (Q20331G9-S10 with C3758)

  2. Has anyone figured out how to get this start on power? I have to press the power button after power loss. I checked the bios with no luck, so it should just be a jumper somewhere.
