Review on 🔌 Vilros USB-C Power Supply with On/Off Switch - Compatible with Raspberry Pi 4 & 400 by Brandon Baird

No instructions, that's important. Do not insert the brass posts into the body first. First take 4 brass bolts with a hex on one end and a threaded rod and place the threaded shaft part from the bottom of the PI board to the top. Then screw on the knurled nuts. Then place the circuit board in the case, you may have to tip it sideways to insert it but it goes in, then screw in the small pan head screws from the underside outside of the case. On a typical computer motherboard, the standoffs screw into the case first, but it's the other way around. There's also no guidance on where to place the heatsinks, so google it, it's pretty obvious anyway.
