A mini-ITX N100 NAS board, (well) made in China

March 20, 2024

Today I bought the motherboard for my main server on AliExpress: a mini-ITX NAS board powered by an Intel N100, made by CWWK (also sold under the Topton brand), for R$1,198.50 (US$224.99). Boards like this pack into 17 × 17 cm what used to require dedicated expansion cards: 6 SATA ports, 2 M.2 NVMe slots, and 4 2.5 Gb network ports, paired with an energy-efficient processor. The catch is that information is scattered across the product listing, online forums, and the silkscreen on the board itself, so I’ve compiled the full spec sheet here.

Black mini-ITX motherboard with a copper plate over the processor, four network ports, six SATA connectors and two M.2 slots, next to a DDR5 memory stick and a cooler — The board in the listing photo.

Spec sheet

Identification

Manufacturer (OEM): CWWK (ChangWang), also sold as Topton; listed under the SZJN brand
Board code: CW-ADLN-NAS, version 1.0.0
Origin: mainland China

Processor and memory

Intel N100 (Alder Lake-N) soldered to the board (BGA), with a copper plate over the chip and mounting holes for LGA 115X coolers (75 × 75 mm)
1 DDR5 SO-DIMM slot: 4800 MT/s native, compatible with non-ECC 5200 and 5600 modules, up to 32 GB

Storage

6 SATA 3.0 ports: SATA1 is native to the N100; SATA 2 through 6 go through a JMicron JMB585 controller
2 M.2 2280 NVMe slots, each on PCIe 3.0 x1
1 PCIe 3.0 x1 slot, which shares lanes with the second M.2: it’s one or the other; you can’t use both simultaneously

Network

4 RJ-45 2.5 Gb ports, with Intel I226-V controllers
Since it’s a recent controller, it needs an up-to-date kernel: Proxmox VE 8.x, OPNsense 23.x or later, pfSense CE 2.7 or later, TrueNAS Scale, and recent Linux distributions

Video, USB, and audio

HDMI 2.1 and DisplayPort 1.4b, both up to 4K at 60 Hz
1 USB 3.0 Type-A, 2 USB 2.0 Type-A, and 1 USB-C (at USB 2.0 speed)
Realtek ALC897 audio, with a combined 3.5 mm headphone and microphone jack

Form factor and power

Mini-ITX, 17 × 17 cm
24-pin ATX connector and 4-pin 12 V connector: both are required for the board to power on
AT/ATX mode jumper (in AT mode, the board turns on by itself as soon as it gets power)

Internal headers

2 PWM fan headers (CPU_FAN and SYS_FAN)
TPM header (ASUS standard, 14-pin SPI)
USB 2.0 header and 2 internal USB 2.0 Type-A ports
Front panel header (FPANEL)

Before you build

A warning from the listing that’s worth repeating: the CR2032 CMOS battery is removed before shipping due to international air transit regulations, so make sure to have one on hand.

The listing

Listings like this change or disappear without notice, so I saved a copy of the listing at the time of purchase (PDF, 2.4 MB), with the seller’s photos and full description.

Update (September 2026)

Two and a half years later, the board is still going strong in my main server. The full configuration is on the setup page.
