Raspberry SC15184 Pi 4 Model B 2019 Quad Core 64… vs Argon ONE M.2 Aluminum Case for Raspberry Pi 4… — Head-to-Head (2026)

Our verdict

Raspberry SC15184 Pi 4 Model B 2019 Quad Core 64… is our pick.

Buy the Raspberry Pi 4 Model B (2GB) first. The Argon ONE M.2 is a case that does nothing without a Pi 4 inside it, so it can't beat the board it was built for. If you already own a Pi 4, though, the Argon ONE M.2 is the best upgrade you can make in 2026: it replaces microSD boot with an M.2 SATA SSD and adds a 30mm fan, two full-size HDMI ports and a safe-shutdown button.

Buy the Raspberry Pi 4 Model B (2GB) if you don't own a Pi 4 yet and want a cheap, well-supported Linux board with a quad-core Cortex-A72, dual-band Wi-Fi, two USB 3.0 ports and dual 4Kp60 output for a headless server, a retro emulation box or GPIO projects. Buy the Argon ONE M.2 if you already have a Pi 4 (any RAM size) and want it to run 24/7 as a small desktop, media center or home server that boots from an SSD, stays cool under sustained load and shuts down safely at the push of a button.
