TL;DR: The Minisforum N5 Max is a real product category first: a 5-bay NAS built around the same Ryzen AI Max+ 395 / 128GB platform as the Strix Halo mini PCs, so it runs gpt-oss-120b at ~31 tok/s while idling at 30–35W. You pay $3,599 for the 128GB version — about $1,400 more than a mini PC with the identical chip. That premium buys drive bays, dual 10GbE, and an always-on form factor, not one extra token per second.

	N5 Max 128GB	GMKtec EVO-X2 128GB	Used RTX 3090 tower
Best for	One always-on box: 120B-class MoE + bulk storage	Same inference, storage already solved	Fastest on everything that fits in 24GB
Price / Cost	$3,599 (list $4,499)	~$2,200 (Amazon, Sep 2026)	~$1,343 card, ~$2,700–$3,000 build
gpt-oss-120b	~31 tok/s	~31 tok/s	won’t fit (63.4GB)
The catch	$1,400 premium over the same silicon	You still need somewhere to put 200TB	24GB ceiling, 80–120W system idle

Honest take: If you already own a NAS — or don’t need five spinning drives — buy the EVO-X2 and keep $1,400. The N5 Max only wins if you were genuinely about to buy both a Strix Halo mini PC and a multi-bay NAS, and want them to be one quiet 35W box.

Minisforum spent 2026 turning the NAS into an AI appliance. The N5 Max shipped in April with AMD’s Strix Halo flagship inside a five-bay chassis, and at IFA 2026 in September the company announced a follow-up, the AI Agent NAS N5 Max-P495, on the new Ryzen AI Max+ Pro 495. The pitch is seductive: your model library, your files, and your inference engine in one low-power box that never turns off.

The question a home-labber actually needs answered is narrower: is this better than the Strix Halo mini PCs we’ve already benchmarked, or is it the same machine with a rent markup on the drive bays? Check your own model-plus-context against the VRAM calculator first — if everything you run fits in 24GB, most of this article’s math tilts a different direction.

What the N5 Max actually is

The spec sheet reads like someone stapled a GMKtec EVO-X2 to a Synology:

CPU/GPU: Ryzen AI Max+ 395 — 16 Zen 5 cores / 32 threads up to 5.1 GHz, Radeon 8060S iGPU with 40 CUs, and an NPU, for a combined 126 TOPS (Minisforum)
Memory: 64GB or 128GB LPDDR5X-8000 on a 256-bit bus — the same ~256 GB/s that defines every Strix Halo machine. Soldered, not upgradeable
Storage: five 3.5” HDD bays plus five M.2 NVMe slots, up to 200TB advertised, with RAID 0/1/5/6 and RAIDZ support (VideoCardz)
Networking/IO: dual 10GbE, two USB4 v2 ports at 80 Gbps, HDMI 2.1
Software: Minisforum’s NAS OS with OpenClaw pre-installed on the 128GB system drive — the local agent framework that routes natural-language commands to an LLM for photo search, document automation, and file wrangling

Pricing moved around in 2026 the way all AI hardware pricing has. The 64GB config launched at a $2,469 early-bird (Liliputing) and settled at $2,899 list. The 128GB config — the only one worth discussing for local AI — lists at $4,499 and sells for $3,599 as of September 2026. Skip the 64GB version: the whole point of Strix Halo is loading models a discrete GPU can’t hold, and 64GB puts gpt-oss-120b out of reach.

The inference numbers: identical silicon, identical speed

There is no NAS bonus and no NAS penalty on tokens per second. Decode speed on Strix Halo is memory-bandwidth-bound, and the N5 Max has the same 256 GB/s LPDDR5X-8000 as every other Ryzen AI Max+ 395 machine. Our numbers from the Beelink GTR9 Pro vs EVO-X2 comparison — both 395/128GB boxes — transfer directly:

Model	Strix Halo 395 / 128GB	Used RTX 3090 24GB
gpt-oss-120b (MXFP4, 63.4GB)	31.41 tok/s at 125–128W wall	won’t fit
Llama-class 70B dense Q4	~5 tok/s	won’t fit (offload: 2–5 tok/s)
gpt-oss-20b	fits easily	161 tok/s

That table is the entire buying decision in miniature. Strix Halo — in NAS or mini PC form — exists for the 60–120GB model class: big MoE models like gpt-oss-120b, where ~~31 tok/s is comfortably past reading speed and no consumer GPU can even load the weights. A used RTX 3090 (~~$1,343 average sold price, September 2026) is roughly 3× faster on everything that fits in 24GB and useless one gigabyte past it. Dense 70B remains the worst case for both: ~5 tok/s on Strix Halo is usable for batch work, painful for chat — the full breakdown is in our 128GB unified memory tier guide.

The 200TB of storage does earn its keep in one specific way: model libraries are huge now. gpt-oss-120b is 63.4GB, a 70B Q4 GGUF is ~42GB, and a working collection of a dozen models crosses half a terabyte before you add a single photo backup. Pulling those off local NVMe instead of over the network is the difference between an 18-second and a minute-plus model swap — the same SATA-vs-NVMe cold-start gap we measured in the Ollama reloading fix.

The always-on math is the strongest argument

ServeTheHome’s review measured the N5 Max at 30–35W idle with drives spun down, 42–45W with disks spinning, 50–60W during active file access, and about 90W during AI inference, peaking at 165W. Those are NAS-class numbers attached to a 120B-capable inference engine.

Run the electricity math at the US average $0.12/kWh: 35W around the clock is 307 kWh a year — about $37/year. A mid-tier tower with a used RTX 3090 idles at 80–120W as a complete system, per our power bill breakdown — call it $84–$126/year before it generates a single token. The N5 Max saves roughly $50–$90 a year in idle draw alone, runs from a laptop-class power envelope, and doesn’t heat the room it lives in.

That’s the honest case for the NAS form factor: not speed, but the economics and ergonomics of never turning it off. An always-on OpenClaw agent, a family-facing Open WebUI instance, overnight batch jobs against your own documents — these are workloads where a 35W idle floor matters more than peak tok/s.

One caveat belongs in this section, not a footnote: OpenClaw ships pre-installed, and TechRadar raised a fair eyebrow at putting an agent framework with a string of recent security issues on the same box that holds all your data. Minisforum’s counter is that everything runs in a local closed loop. Both things can be true. Treat the agent like any other service on a NAS: keep it off the open internet, no port forwarding, VPN-only remote access.

The problem you’ll actually hit: the GPU can’t see the memory

Same silicon means same setup traps. Out of the box on Linux, the Radeon 8060S may only be able to address 4–16GB of that 128GB pool — models fail to load or silently fall back to CPU. The fix is the same one from our Strix Halo guide: set UMA Frame Buffer Size to 512MB in BIOS, then hand the memory to the GPU driver via kernel parameters:

$ sudo nano /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash amd_iommu=off amdgpu.gttsize=131072 ttm.pages_limit=31457280"
$ sudo update-grub && sudo reboot

After the reboot, a 63.4GB gpt-oss-120b load succeeds and ollama ps shows the model resident on GPU instead of erroring out. If you stay on the pre-installed NAS OS and its one-click OpenClaw deployment, Minisforum has done this plumbing for you — the trap is for people who wipe it and install stock Ubuntu, which, on a machine you bought partly for the storage OS, you probably shouldn’t.

Should you wait for the N5 Max-P495?

No — and the spec sheet says why. The IFA version swaps in the Ryzen AI Max+ Pro 495 (“Gorgon Halo”): same 16 Zen 5 cores at 5.2 GHz instead of 5.1, same 40 CUs in a Radeon 8065S at 3.0 GHz instead of 2.9, 131 TOPS instead of 126, and LPDDR5X-8533 instead of 8000. Notebookcheck’s early numbers put it about 3–4% ahead of the 395 on CPU benchmarks. The memory bump is the only part that touches inference: 8533 MT/s on the same 256-bit bus is ~273 GB/s, about 7% more bandwidth, which should move gpt-oss-120b from ~31 to roughly 33 tok/s — an estimate, since nobody has published N5 Max-P495 LLM benchmarks yet.

The one real capability change is the 192GB memory ceiling, with up to 160GB allocatable to the GPU. That’s a genuinely new tier — it fits Q4 quants of models the 128GB machines can’t hold. But Minisforum isn’t selling it like a normal product: 192GB Gorgon Halo configs are quoted at $7,500–$8,000 and handled as individual custom orders, not standard listings. N5 Max-P495 pricing was still unannounced as of September 22, with sales “expected to begin during September” (PR Newswire). A 2–7% speed bump at an unknown price, or a 192GB config at double the money, is not worth waiting for when the 395 version is $900 off list today. At $7,500+ you’re in DGX Spark and Mac Studio territory anyway, and that’s a different comparison.

What to actually buy

Prices as of September 2026, all verified above:

Your situation	The machine	Price	Where
Replacing a NAS and adding local AI — want one 35W always-on box	Minisforum N5 Max 128GB	$3,599	Check price
Want 128GB Strix Halo inference; storage is already solved	GMKtec EVO-X2 128GB	~$3,649	Check price
Everything you run fits in 24GB — speed over capacity	Used RTX 3090 tower	~$1,343 card / ~$2,700 build	Check price
Undecided — test your workload on rented hardware first	Rented 3090, by the hour	from $0.07/hr	Vast.ai

The middle rows deserve one more sentence each. The EVO-X2 at ~$2,200 is the same chip, same 128GB, same ~31 tok/s — the N5 Max’s $1,400 premium is purely bays, 10GbE, and packaging, and a USB4 DAS or your existing NAS covers storage for a fraction of that. The 3090 tower is the opposite trade: 3× the speed on mid-size models, zero access to the 120B class, and about triple the idle power — our $3K/$6K/$10K build guide maps that fork in detail. And if you’d use the box as a coding-agent backend, the same capacity logic applies to local BYOK setups on aicoderscope, where a 120B MoE at 31 tok/s is a very different assistant than a 20B at 161.

FAQ

Can the N5 Max run 70B models? Yes, but dense 70B at Q4 decodes at ~5 tok/s — fine for overnight batch work, frustrating for interactive chat. The machine’s sweet spot is MoE models: gpt-oss-120b at ~31 tok/s, plus the 30B-class MoE models that top 100 tok/s on this platform.

Is the N5 Max better than the MS-S1 Max at the same job? They share the AI story; the split is storage vs. expansion. The MS-S1 Max is a workstation with a PCIe slot and no drive bays; the N5 Max trades the slot for five bays and RAID. Buy on which of those you’ll actually populate.

Does OpenClaw on the N5 Max need an internet connection? No — Minisforum’s one-click deployment runs the full agent loop locally against the on-board LLM. Given OpenClaw’s 2026 security track record, keep it that way: LAN or VPN access only, no port forwarding.

How much does it cost to leave running 24/7? At the measured 30–35W spun-down idle and $0.12/kWh, about $3/month. Spinning drives add ~10W; inference bursts to ~90W but is a small share of wall-clock time on a personal server.

Is the 64GB version worth $2,899? Not for local AI. It can’t hold gpt-oss-120b (63.4GB weights alone), which removes the main reason to buy Strix Halo over a $1,343 used RTX 3090 that’s 3× faster on smaller models.
