The standoffs and screws provided are not the standard 2.5mm options, so I used my own standoffs, nuts (which are used as washers) and screws used for assembly. Once installed, it worked fine with low power devices (keyboard, mouse), but didn't provide enough power to the SSD in the USB enclosure. Connecting an external power supply to the USB-C port solved this problem, so the PI4 now has 2 power supplies. A power supply with two USB-C ports reduces the number of connected devices, but still leaves the PI with two power cables attached.
