Pros & Cons
Pros
- ✓ Included M.2 SATA board takes any B-Key or B+M Key SSD for SSD boot
- ✓ Aluminum body acts as integrated heatsink plus a 30mm active fan
- ✓ Configurable Argon ONE script sets fan curve instead of always-on noise

- ✓ One-push power button triggers a safe shutdown, protecting the SD card
Cons
- ✗ Argon IR remote is sold separately despite the built-in IR receiver
- ✗ M.2 SATA only - NVMe drives are not supported by the expansion board
- ✗ Raspberry Pi 4 specific, so no Pi 5 or Pi 400 compatibility
- ✗ Fan control needs the Argon script installed per OS, not plug-and-play
Manufacturer description
The Argon ONE M.2 turns a Raspberry Pi 4 into a tidy, SSD-backed desktop machine. The aluminum shell doubles as an integrated heatsink for passive cooling, and a 30mm fan handles the rest through the configurable Argon ONE script, so you can tune fan speed to your workload instead of running it flat out. The included M.2 SATA expansion board accepts any B-Key or B+M Key M.2 SATA SSD, letting you boot and store from solid state instead of a microSD card. Argon Forty also relocates the Pi's awkward micro-HDMI outputs to two full-size HDMI ports on the back, alongside a cable management channel…
