| M.2 NVMe | Samsung 970 EVO Plus | 500GB / 1TB | PCIe 3.0 | £45–90 |
| M.2 NVMe | WD Blue SN570 | 500GB / 1TB / 2TB | PCIe 3.0 | £40–100 |
| 2.5″ SATA SSD | Samsung 870 EVO | 1TB / 2TB / 4TB | SATA III | £60–200 |
| 2.5″ SATA HDD | Seagate BarraCuda | 1TB / 2TB / 4TB | SATA III | £40–100 |
Power Supply & Fanless Thermal Design
The 36W adapter (12V 3A) provides sufficient power for the 6W TDP Intel N200. Completely fanless and passively cooled—zero noise production. Ideal for recording studios, libraries, bedrooms, and quiet offices.
Display & Legacy Support
HDMI 2.0b and VGA (15-pin) analog connector. VGA is a legacy option for older projectors and displays. Dual-display support possible with HDMI + VGA simultaneously. USB to HDMI adapters can add additional displays.
WiFi 6 & Bluetooth 5.0
WiFi 6 (802.11ax) dual-band with up to 9.6 Gbps theoretical throughput. Bluetooth 5.0 for wireless peripherals. Gigabit Ethernet (1000 Mbps) for wired connections. WiFi module is soldered and not upgradeable.
Upgradeability Score
5/10 — Practical for storage and RAM within limits. Single RAM slot (16GB max) is restrictive. Dual storage (M.2 + SATA) is a strong point. VGA port adds legacy compatibility. Best for budget users and silent deployments.
FAQs
What is the difference between N100 and N200?
The N200 is a newer, slightly faster variant of the N100 with improved efficiency. Both are 4-core Intel Atom processors with 6W TDP. Real-world performance difference is minimal.
Can I use a 2.5″ HDD in the SATA bay?
Yes, the SATA bay supports both SSDs and HDDs. HDD is cheaper but slower. SSD recommended for better overall system responsiveness.
Is this suitable for 4K video?
The dual HDMI 2.0b output supports 4K@30Hz. For 4K@60Hz, use external USB-C adapters if available. Consider a more powerful mini PC for 4K editing or streaming.
Can I upgrade RAM to 32GB?
No. Only one SO-DIMM slot exists with a 16GB maximum. DDR5 is not supported. Total max RAM is 16GB.
Why is there a VGA port?
VGA provides legacy display compatibility for older projectors, office monitors, and equipment. Modern displays use HDMI or DisplayPort; VGA is a fallback option.
