The review

Review: GMKtec NucBox G10 Mini PC

The GMKtec NucBox G10 is a small mini PC built on an AMD Ryzen 5 3500U, with two DDR4 slots, two M.2 NVMe slots and a 2.5GbE port[2]. This listing is the 16GB RAM and 1TB SSD configuration[1]. The chip is from 2019, so think home server or office box, not workstation[3].

Key facts

  • AMD Ryzen 5 3500U: 4 cores, 8 threads, 2.1GHz base, up to 3.7GHz, Radeon Vega 8 graphics[3].
  • 16GB DDR4 and a 1TB SSD, with two M.2 PCIe 3.0 slots for up to 16TB[1, 2].
  • 2.5GbE, Wi-Fi 5 and Bluetooth 5.0[2].
  • Three screens: HDMI and DisplayPort at 4K 60Hz, USB-C at 4K 30Hz[2].

What hardware is inside?

The Ryzen 5 3500U is a laptop chip from early 2019 with 4 cores, 8 threads, 4MB of L3 cache and Radeon Vega 8 graphics at 1200MHz[3]. AMD rates it at 15W, configurable from 12W to 35W. GMKtec runs it at 25W, with a 35W peak[2].

Memory sits in two DDR4 SO-DIMM slots running at 2400 MT/s[2]. This configuration ships with 16GB of DDR4 and a 1TB SSD[1]. GMKtec puts Windows 11 Pro on the configured models[2].

The case is 103 × 98 × 42mm[2].

How far can you upgrade it?

Storage: two M.2 2280 PCIe 3.0 x4 slots. The 1TB SSD takes one, and the other is free. GMKtec rates the pair at up to 16TB (2 × 8TB)[2]. There’s no 2.5-inch drive bay in GMKtec’s spec list, so extra storage is NVMe only.

Memory: GMKtec says the two slots take up to 64GB[2]. The Amazon listing quotes that 64GB figure but also says the chip supports 32GB[1], and AMD’s page doesn’t give a maximum. 32GB (2 × 16GB) is the safe upgrade. 64GB is GMKtec’s claim to test yourself.

GMKtec also sells a barebone G10 with no RAM, SSD or OS, if you have parts on the shelf[2].

What ports does it have, and how many screens?

From GMKtec’s spec table[2]:

  • Two USB 3.2 Gen1 (5Gb/s) USB-A ports and one USB 2.0 port.
  • Two USB-C ports. One does DisplayPort 1.4 video, USB 3.2 Gen1 data and power delivery. The other is for power only.
  • One HDMI 2.1 and one DisplayPort 1.4, both 4K at 60Hz.
  • One 2.5GbE port and a 3.5mm headset jack.

That answers the question the original review left open: only one USB-C port carries video[2]. It runs three screens at once through HDMI, DisplayPort and USB-C[1]. The USB-C screen gets 4K at 30Hz, though, so put your main monitor on HDMI or DisplayPort[2].

What about networking and power?

The wired port is a Realtek RTL8125BG at up to 2.5Gb/s. GMKtec’s table calls it “Gigabit LAN”, but the chip and the 2500Mbps figure make it 2.5GbE[1, 2]. Wireless is Wi-Fi 5 (Realtek RTL8822CE) and Bluetooth 5.0[2].

It runs from a 19V / 3.42A USB-C power supply, and GMKtec says it also accepts other PD and non-PD chargers[2]. In the box: the power adapter, an HDMI cable, a VESA mount and a manual[2].

What would a developer use it for?

A home server is the obvious job. Two NVMe slots, room for more RAM and a 2.5GbE port suit a Proxmox node, a few containers, a Git mirror or a media server[2]. The VESA mount puts it behind a monitor or under a shelf.

As a desktop it handles a browser, an editor and office work. GMKtec pitches it at home office, education and light office use[2]. Four cores from 2019 won’t enjoy big builds, heavy VMs or modern games[3].

What isn’t settled?

Two things depend on where you buy. The Amazon listing advertises a 3-year GMKtec warranty, with whole-unit replacement in year one and major parts in years two and three[1]. GMKtec’s own US store shows a 1-year warranty[2]. And Amazon’s operating-system field just says “OS”, so check the listing if you need Windows 11 Pro preinstalled[1]. The 64GB memory ceiling, above, is GMKtec’s claim and not one AMD confirms.

Pros and Cons

Pros

  • Two M.2 PCIe 3.0 slots and two SO-DIMM slots, so it grows with you[2].
  • 2.5GbE wired networking[2].
  • Three display outputs, two of them 4K at 60Hz[2].
  • USB-C power, a VESA mount and an HDMI cable in the box[2].

Cons

  • A 2019 quad-core chip, slow for heavy work[3].
  • The USB-C display tops out at 4K 30Hz[2].
  • USB-A ports are 5Gb/s, and wireless is Wi-Fi 5[2].
  • DDR4 at 2400 MT/s, and no 2.5-inch drive bay[2].

Final Verdict

Get the GMKtec G10 if you want a small box for a home server, a Proxmox node or an office desk, and you value two NVMe slots and 2.5GbE over CPU speed[2]. The 16GB and 1TB here are a sensible start[1]. Skip it if you compile big projects, need Wi-Fi 6, or want three screens all at 4K 60Hz[2].

Key Takeaways

  • Ryzen 5 3500U: 4 cores, 8 threads, from 2019[3].
  • Only one USB-C port does video, at 4K 30Hz. The other is power in[2].
  • Two M.2 PCIe 3.0 slots, one free[2].
  • Check the warranty term on the listing you buy from[1, 2].

Frequently Asked Questions

How much RAM can it take?

It ships with 16GB in two DDR4 SO-DIMM slots. GMKtec rates it for up to 64GB; 32GB is the safe upgrade[1, 2].

Can I add another SSD?

Yes. There’s a second M.2 2280 PCIe 3.0 x4 slot, for up to 16TB across both[2].

Can it run three 4K monitors?

Three screens, yes. HDMI and DisplayPort run 4K at 60Hz, and the USB-C screen runs 4K at 30Hz[2].

Is the Ethernet 2.5GbE or gigabit?

2.5GbE. It’s a Realtek RTL8125BG that also runs at 1Gb/s, 100Mb/s and 10Mb/s[2].

Does it come with Windows?

GMKtec ships configured G10s with Windows 11 Pro[2]. The Amazon listing doesn’t name the OS, so check it before you buy[1].

How to build a better desk setup

A good setup is a set of small fixes: cables out of the way, the camera at eye level, and audio that doesn't make colleagues wince.

Video calls

  • Light first. A cheap webcam with a window in front of you beats an expensive one with a window behind you.
  • 1080p at 30 fps is what most call apps send anyway. 4K webcams help mostly when you crop or zoom.
  • Put the camera at eye level, on the monitor or a small stand.

Microphones

  • USB microphones plug straight in. XLR microphones need an audio interface but upgrade further.
  • Cardioid pickup records what is in front and rejects the rest: the right pattern for one person at a desk.
  • Distance matters more than price: 10–20 cm from your mouth, on an arm, with a pop filter.
  • Headphone monitoring (a jack on the mic) lets you hear yourself without delay.

Controls and shortcuts

  • Macro pads and stream decks run one-press actions: mute, start a recording, open the project, switch scenes. Check software support for your operating system and apps.

Desk and cables

  • A desk mat protects the desk and gives the mouse a consistent surface.
  • A laptop stand lifts the screen to eye level; pair it with an external keyboard.
  • Cable clips, trays and sleeves: route power along the back of the desk and leave short, labelled leads at the front.
  • Keycaps: check the stem type (most are MX-style cross stems), the layout (especially bottom row widths) and the profile (Cherry, OEM, SA, XDA).
