When you think of a brand new mini PC in 2026, you probably expect the latest silicon — maybe an Intel Core Ultra or a Ryzen 8000 series chip. But GMKtec is going against the grain with its newly launched NucBox M3 Pro. Instead of chasing the newest hardware, the company has doubled down on value, packing a slightly older but still highly capable Intel Core i5-13500H into a compact chassis. The result? A barebone system that starts at just $329.99 — and with a coupon code, it gets even cheaper.
But is this "dated" processor strategy a smart move or a deal-breaker? Let's break down what you're actually getting for your money.
The "Old" CPU That’s Still More Than Enough
The heart of the GMKtec NucBox M3 Pro is the Intel Core i5-13500H — a mid-range Raptor Lake-H mobile processor. Yes, it's not the absolute newest chip on the block, but let’s be realistic: for everyday computing, office work, heavy multitasking, and even 4K media streaming, this CPU is still a beast. With 12 cores (4 Performance + 8 Efficient) and 16 threads, it can turbo boost up to 4.7 GHz.
Paired with the integrated Intel Iris Xe G7 graphics, the NucBox M3 Pro can even handle light gaming — think League of Legends, CS:GO, or older AAA titles at lower settings. It’s not a gaming rig, but for a work-from-home or living room media hub, it’s surprisingly versatile.
Where GMKtec made an obvious cost-cutting move is the memory. Although the i5-13500H supports DDR5, the M3 Pro ships with a DDR4 motherboard. The silver lining? You get two SO-DIMM slots supporting up to 64GB of RAM at 3200 MHz. For most users, DDR4 vs. DDR5 won’t be noticeable in daily tasks, and the savings are passed directly to you.
Storage That Scales Like Crazy
One area where the NucBox M3 Pro doesn't compromise is storage. Inside the tiny frame, you’ll find two M.2 slots, each capable of holding up to an 8TB SSD. That’s a total of 16TB of potential storage — enough for a massive media server, a video editing cache, or a small business database. GMKtec even highlights a popular drive like the 1TB WD_Black SN7100 (currently $184.99 on Amazon) as a reference.
Whether you're archiving photos or running a home lab, you won't feel boxed in.
Ports and Connectivity: Small Box, Big Reach
Despite measuring just 128.5 x 127 x 51mm (about the size of a paperback novel), the NucBox M3 Pro offers a robust selection of ports:
- 1x 5Gbps USB Type-C with DisplayPort alt-mode
- 1x USB 2.0 Type-A (great for keyboard/mouse)
- 3x USB 3.2 Gen 2 Type-A (10Gbps each)
- 1x 2.5G LAN – faster than standard Gigabit Ethernet
- 1x HDMI 2.0 (supports 4K at 60Hz)
- 1x 3.5mm audio combo jack
For wireless, you get WiFi 6 and Bluetooth 5.2. That’s not WiFi 7 or 6E, but again — at this price point, it's perfectly adequate for streaming, video calls, and file transfers.
GMKtec also touts a refined cooling solution that allows the i5-13500H to run at up to 45W TDP in performance mode. That means the CPU won't throttle easily under sustained loads, a common weakness in many budget mini PCs.
Pricing and Configurations: Where the Magic Happens
Here’s where things get interesting. The barebone model (no RAM, no storage, no OS) is priced at 15 — landing at just $314.99. That’s incredible value for a mini PC with this much connectivity and a solid 12-core processor.
If you prefer a ready-to-run system, GMKtec offers two pre-configured variants:
- 16GB RAM + 512GB SSD – $479.99
- 32GB RAM + 1TB SSD – $679.99

Who Is This Mini PC For?
The GMKtec NucBox M3 Pro isn't trying to win any performance crowns. Instead, it targets the savvy buyer who understands that "newer" doesn't always mean "better for my needs."
- Remote workers and students – Handles Zoom, Office, browsers, and light coding with ease.
- Home theater enthusiasts – Small footprint, 4K output via HDMI or USB-C DP, and silent cooling.
- Small business owners – Affordable point-of-sale or kiosk PC with dual storage for redundancy.
- Homelab tinkerers – Two M.2 slots, 2.5G LAN, and 64GB RAM support make it a great Proxmox or TrueNAS starter box.
The only people who should look elsewhere are hardcore gamers or professionals who need DDR5 bandwidth (e.g., heavy data science or high-end video editing). For everyone else, the i5-13500H is still a workhorse, and the DDR4 trade-off is barely noticeable.
Final Verdict: A Smart, Honest Budget PC
GMKtec could have slapped a newer, more expensive CPU into the NucBox M3 Pro and charged $500 for the barebone. Instead, they chose to build a value-first machine that leverages mature, reliable hardware. The Intel Core i5-13500H might be from the previous generation, but it’s still faster than many low-end current-gen U-series chips.
The DDR4 decision feels like a sensible cost-saving measure, not a corner cut. With up to 64GB, you won't feel memory-starved. And with 16TB of possible SSD storage, this little box can grow with you.
At 314.99 with the coupon), the barebone NucBox M3 Pro is one of the best sub-$350 mini PCs you can buy today. If you already have spare DDR4 SO-DIMMs and an M.2 SSD lying around, it's an absolute no-brainer.
