GMKtec G11 Plus Review: The Dual 2.5GbE Mini PC for Home Labs and Offices
The GMKtec G11 Plus is a small, quiet desktop for the jobs a full tower is overkill for: office work, streaming, a home server, a compact NAS or a software firewall. Its standout feature is the pair of 2.5 Gigabit Ethernet ports, which is rare at this size, backed by triple 4K display output, Wi-Fi 6E and a 16 GB dual-channel, upgradeable setup. The trade-off is the AMD Ryzen 5 3500U, an older low-power chip that is fine for everyday tasks but no match for a current mainstream CPU under heavy load, and there is no USB4 or Thunderbolt. Treat it as a capable, efficient little workhorse rather than a gaming rig.

Who is the GMKtec G11 Plus for?
The G11 Plus is for anyone who wants a real Windows desktop or a small always-on machine without giving up a corner of the desk. The dual 2.5 Gigabit Ethernet ports are the reason to pick it over a generic mini PC: they let the same box serve as a software router or firewall, a compact NAS, a virtualisation host or an isolated network for cameras and smart-home gear. The triple 4K output suits a trading or editing desk and digital signage, and the VESA mount in the box means it can disappear behind a monitor or a TV. It shares its quiet, compact chassis with the rest of the GMKtec G-series, so it is small enough to forget once it is set up.
What the GMKtec G11 Plus offers
Under the hood is an AMD Ryzen 5 3500U, a four-core, eight-thread processor with a 2.1 GHz base clock and a boost up to 3.7 GHz, paired with AMD Radeon Vega 8 integrated graphics clocked up to 1200 MHz. It ships with 16 GB of dual-channel DDR4 across two SO-DIMM slots and supports up to 32 GB, and storage is two M.2 2280 PCIe 3.0 slots (one NVMe, one SATA/NVMe) with the 256 GB SSD installed and room to add a second drive, expandable up to 16 TB across both. Networking is where it stands out: two 2.5 Gigabit RJ45 ports plus a Wi-Fi 6E RZ616 module rated up to 2.4 Gbps and Bluetooth 5.2. For displays it drives three screens at once over two HDMI 2.0 ports and a USB-C port with DisplayPort Alt Mode, each up to 4K at 60Hz. Around the body it has a 3.5 mm audio jack, a security lock slot, and USB ports split between the front panel (two 10Gbps Type-A and a 10Gbps Type-C) and the back (two 5Gbps Type-A). Windows 11 Pro comes pre-installed.
What to know before you buy
The single biggest consideration is the processor. The Ryzen 5 3500U is an older, low-power chip built for efficiency and reliability, not speed: it handles browsing, documents, video and light multitasking comfortably, but it is not a gaming or heavy-video-editing chip, and its performance modes run from 15W up to a 35W peak. Connectivity has clear limits: no USB4 or Thunderbolt, no SD card slot, and no built-in speakers or microphone. The USB-C port carries video and data but not power input, so the machine runs from its 19V adapter. The optional power cable and the barebone configuration (no memory, SSD or OS) mean you should pick the built-up version if you want a machine that works out of the box. The warranty is one year.
Is the GMKtec G11 Plus worth it?
For a quiet, compact do-it-all desktop, yes. What the money buys is a licensed Windows 11 Pro machine with 16 GB of dual-channel DDR4, a 256 GB PCIe M.2 SSD and a free second M.2 bay, two 2.5 Gigabit Ethernet ports, Wi-Fi 6E and Bluetooth 5.2, triple 4K display output, and a VESA mount in the box. The value is strongest for buyers who will actually use the dual NICs, the triple display or the upgradeable slots, and weakest for anyone who needs peak CPU performance or Thunderbolt. Inside its lane, which is office work, streaming, home-lab and light server duty in a box that sits behind a screen, it is easy to recommend.
Frequently asked questions
Does the GMKtec G11 Plus have dual 2.5 Gigabit Ethernet?
Yes. It has two 2.5 Gigabit RJ45 ports, which is what makes it a popular pick for a software firewall, a router, a NAS or a small home server. The rest of the networking is Wi-Fi 6E and Bluetooth 5.2.
Can the GMKtec G11 Plus drive three 4K monitors?
Yes. It has two HDMI 2.0 ports and one USB-C port with DisplayPort Alt Mode, each supporting up to 4K at 60Hz, for three independent screens at once. The USB-C port carries video and data but not power input.
Does the GMKtec G11 Plus come with Windows 11 Pro?
The configured versions ship with Windows 11 Pro pre-installed. The barebone option comes without memory, SSD or an operating system, so you install your own DDR4 memory, M.2 SSD and OS before powering it on.
How much memory and storage can the GMKtec G11 Plus take?
It ships with 16 GB of dual-channel DDR4 across two SO-DIMM slots and supports up to 32 GB. Storage is two M.2 2280 PCIe 3.0 slots, one NVMe and one SATA/NVMe, with this model carrying a 256 GB SSD and expansion up to 16 TB across both.
Is the GMKtec G11 Plus good for gaming?
Only for light or older titles. The integrated Radeon Vega 8 graphics run at up to 1200 MHz, which is fine for casual games and emulation but not for demanding modern titles. Its strengths are office work, media, networking and home-lab tasks.
Is the GMKtec G11 Plus a good choice for a firewall or home server?
Its dual 2.5 Gigabit Ethernet ports and low power draw make it a good fit for pfSense or OPNsense, a compact NAS or a virtualisation host. Keep it somewhere with airflow, since sustained load can make it run warm.
