Review on Vilros Raspberry Pi 4 4GB Complete Starter Kit - Black Fan-Cooled Aluminum Case for Heavy-Duty Performance by Jose Strong

I liked everything in one case - I didn't have to worry about the right power supply, heatsink, fan (much needed) and a solid metal case. BUT - you can't close the case with the heatsinks. There are two metal pins on the top of the case that make contact with the Raspberry Pi (no heatsinks) to hold it in place. Once you've attached the heatsinks, you can't close the case. The instructions (very sparse) do not mention this. Building, booting, installing the operating system and getting a fully functional Raspian (Linux) system takes about 30 minutes.
