Review on Smraza Raspberry Pi 4 Model B Case with Fan, Heatsinks, Power Supply, USB Card Reader, HDMI Cable, Adapter (4K Ultra HD) by Drew Diaz

Great case and assortment for Raspberry Pi 4. The fan runs at low power and is very quiet and when I checked the temperature it was between 30 and 40 degrees Celsius vs. my RPi 3 passively cooled in the 50's-70's. Access to the pins on the top makes it easy to switch pins to a more powerful fan or add additional components. I went for the option with all the extras but with silver heatsinks. I also bought a base RPi 4 with black anodized heatsinks. Here I say follow the instructions. It worked for me because I went through steps 1-5 when initially assembling the case. In step 6 you place the heatsinks after step 5 in which you place one of the inner cap layers. The black heatsinks worked well with all chips except the smaller ethernet controller because it was near the edge of the case cutout and the black heatsink was larger than the chip. It fits in a hole but also makes contact with multiple surface mount components. If I had installed the heatsinks first I would not have been able to assemble this layer of the case without cuts. Instead, I used the smaller silver heatsink that came with the case and it was the perfect size for this particular component. For all the accessories/flexibility and the well-made/beautiful body, this is a very good buy.
