Q31100GT S23 Review: Ten 2.5GbE Ports for the Network Die-Hard
The Qotom Q31100GT S23 packs ten Intel I226-V 2.5GbE ports into a compact, fan-cooled chassis. Powered by 11th Gen Tiger Lake processors (up to Core i7), it offers dual DDR4 slots, multiple M.2 and SATA storage options, and rugged build quality. Ideal for routers, firewalls, home labs, and edge computing.
First Impressions: This Thing Has Heft
Unboxing the Qotom Q31100GT S23, the first thing that hits you is the weight – 1.5kg of aluminum alloy. It's solid. This isn't a media player for your living room; it's a purpose-built tool for network pros. The front panel is minimal: power button, CMOS clear, and a few status LEDs. All the action is on the back.
The Main Event: 10x 2.5GbE
This mini PC packs ten Intel I226-V 2.5GbE ports. That's not a typo – ten. Whether you're running a home lab, a small business firewall, a VPN concentrator, or a network monitoring setup, this is exactly what you need. Segment VLANs, aggregate links, direct traffic – you can do it all without dropping cash on a full-size server. The I226-V is a proven controller that handles sustained throughput without breaking a sweat.
Under the Hood: Tiger Lake Options
The S23 series supports Intel 11th Gen Tiger Lake processors, from the Celeron 6305 up to the Core i7-1195G7. There are also H-series options (i5-11300H and i7-11370H) with higher TDPs for more demanding tasks. All come with dual-channel DDR4 memory (up to 64GB). Storage is flexible: one M.2 PCIe 4.0 x4 slot, one M.2 PCIe 3.0 x1 slot, plus a 2.5-inch SATA bay. There's also an M.2 slot for 4G/5G or Wi-Fi, and a SIM card slot. This thing is built for connectivity.
Quiet and Cool Under Pressure
Despite the dense port arrangement, the S23 stays cool – a combination of fanless design and an internal fan. During testing with constant 2.5G traffic, the chassis was warm but not hot, and the fan was barely audible. It's designed for 24/7 operation, and it shows. The included VESA mount lets you tuck it behind a monitor or under a desk, out of sight and mind.
Who Is This For?
- Network Engineers / IT Pros: Use it as a pfSense/OPNsense router, IPS/IDS appliance, or network tap.
- Home Lab Enthusiasts: Perfect for simulating complex network topologies.
- Small to Medium Business: A compact, reliable firewall or VPN server.
- Edge Computing: Deploy it in remote offices or industrial settings where space is tight.
