“Ordered this board for my existing Argon ONE case (board and case can now be purchased as a single unit). Easy install of older Raspbian bootloader to get Pi to boot from Kingston M.2 SSD instead of Micro SD card, now running Manjaro KDE much more quickly and smoothly. Clean installs are also a cinch just by removing the USB connector and connecting computer to the expansion board socket to format/write image. Probably the best RPi4 case/expansion solution currently available. Recommended.”
