Argon ONE M.2: Clever Raspberry Pi 4 housing with potential for improvement Complicated card change Integrated infrared receiver full-size HDMI and M.2 storage Optimize cooling Conclusion and alternatives The manufacturer of a the most sophisticated case for the Raspberry Pi 4 has added: After the Argon ONE, Argon 40 is now offering its successor ONE M.2. As the name suggests, an M.2 SSD can be built into this housing – there are also important improvements in detail.

The Argon ONE M.2 looks very similar to the Argon ONE (without M.2), but is visibly higher. This is not due to the upper part of the housing, which is made of an aluminum alloy, but to the plastic base plate. Compared to the previous model, this grows by almost one centimeter. The additional space enables the installation of an M.2 SSD in the housing, plus HDMI connections in standard format.

Complicated card change The old case had a slot for the micro SD card on the front underside. This is missing in the new version. This is annoying, because to change the micro SD card you first have to pull off the USB3 bridge, unscrew four screws from the bottom of the case and remove the plastic bottom. If you experiment a lot with different operating systems for the Raspberry Pi 4, you will wear out the screws and your patience in the long run.
