Miuzei Case for Raspberry Pi 4, Raspberry Pi 4 B Case with Fan 35mm, 4 Pcs Aluminum Heatsinks Support Rpi 4B 8gb/4gb/2gb (No Raspberry Pi board)

It is well designed but you need to follow the pictures closely during assembly I would purchase another one and probably will if I buy another po 4

Can't easily access the IO pins, camera or DSI display connector. To do so one needs to remove at least 4 layers of the stack and fool around with loose screws and nuts. Furthermore, one cannot snake in an IO connector, nor easily plug in any jumpers or even fan connector pins without use of a fine pair of tweezers or really nice needle nose pliers. I've used a few of these kinds of cases, but this one is the worst for access. Seriously, you have to snake the ribbon cables through two narrow slots? What a bad idea. And really bad if you are thinking about Octoprint.In fairness, the heatsinks look nice, and the fan is recessed into the case. So it looks ok, but really isn't useful for people who want to use the RPI4 to control things, rather than be a geegaw on a desk. The Geekworm cases I used were a heck of a lot easier to use, I have a few of them.My assessment is look elsewhere, the Geekworm offering is a lot more practical. But if you are looking for something to use your RPI4 as a computer, I guess this might be ok. For my use, I cannot recommend this case. Looks ok, hard to use.

For sure, the "Miuzei Case for Raspberry Pi 4 with 35mm Fan and 4 × Aluminum Heat Sinks for Raspberry Pi 4" is far better than the official Raspberry Pi case from/by raspberrypi.org. The official case literally has no ventilation openings; I used the Pi 4 just for browser/shell/RDT and it quickly signaled over-heat warning. The Pi 4 is capable of much greater usage (audio, games, overclocking, etc.) but the standard case is a disaster.The Miuzei case has some pretty good features:* Fits great* Heatsinks allow my usage without the fan* The fan is almost silent at 3.3v* The case is robust* IMHO, it looks nicer than the red/white case* Openings for camera, display, and I/O totally in the right positionsBut it has serious room for improvement:* The layers need to be labeled for proper order and alignment. Knowing from previous bad experiences, I scratched a number in the upper left of each layer before I even attempted to install the Pi.* The fan should have a grill. This is cheap. I will add a grill, but I will also have to buy slightly longer screws.* The power/video/audio connections are not shrouded, meaning it is possible to accidentally stick a connector into the case and short/snag/break components on the Pi. The official case does have this protection, as does a bunch of competitors to Miuzei.* The bottom layer of the case has screw-mount keyholes, but nothing to electrically insulate the bottom of the Pi from metallic screws using the keyholes.* A cheap screwdriver was included, thanks, but I already have a good one, I would rather have a grill.

I order 3 of this Raspberry Pi 4 Kits and 2 out of 3 were missing the screw to attach the fan.Quality Control is not the best.

They can be challenging the first time... Once you understand how each layer interfaces with the board and the last, it becomes super simple to build Pi's in this case. The CPU heatsink is oversized footprint and short on fin depth and comes with incomplete thermal adhesive, which is all actually fine - the point is to cover the width of the raised section of the metal cover on the CPU, and still have the rest of the heat sink underneath the fan section. I have replaced it with a perfectly sized, deeper finned CPU heat sink and the temp numbers under the fan are comparable. I mount these on a shelf with a strip of velcro down one side to hold them onto the shelf (so cables don't drag them around) and use the included rubber adhesive feet on the fan side - which I recommend even in a stand-alone desktop configuration - it will keep things from falling into your fan. I know I've destroyed a 3B+ by accidentally causing a short on 3v3 vs GND, which blew out its 3v3 supply entirely. Blah blah. Enjoy your Pi case. It's a good one. I really like it, and own tons of them in Pi3B and Pi4 form factors.
