GeekwormRaspberry Pi 4 Aluminum Case - Heavy Duty Passive Heat Dissipation Metal Case for Raspberry Pi 4B Only

Fits perfectly, keeps the pi cool and allows silent operation, cut outs for accessories / expansion and included thermal pads, only thing i'd say is the included tool for the screws is a bit soft and easily strips itself so best to use your own tool for the screws. Product itself is sound though!

I am trying Windows 10 (perhaps 11) on the Pi4 and needed a better cooling solution than "none". In summary, for the price (fulfilled by AZ not China) is OK and the quality is OK.I do not like fans (noise, dust build-up, etc.) and Windows does not really have support for Pi fans (variable speed based on CPU temperature) + WiFi has no driver - thus I was not missing anything by using an all-metal enclosure.The quality is OK, very thin paint so don't bash it as it easily scratched. The screws need a bit of grease to assemble. You will need thermal grease if you're going to be use the copper shim (recommended) rather than thermal pad.SD card is a bit hard to insert/remove but then many cases are worse. In any case for Windows you want an external USB3 SSD thus not really an issue. But could be better.In use, it seems to be OK, getting warm (thus good transfer of heat) but still needs to be in a well-ventilated position. In any case it does work, even overclocking the Pi 4 to 2GHz is stable in Windows 10 Arm64.All in all, there are sleeker cases available (Flirc, Argon, etc.) but at almost 2x the cost most times. If you can get one of those, please do. Otherwise this is not bad for just over 10 quid. You can get lots of these direct from China for less but then you need to wait a few weeks. YMMV.

I was worried this would be cheap and shoddily made.The case is surprisingly hefty and appears to be made of aluminium approx 1mm thick. The two sides mate perfectly.I bought this case to protect the pi from dust and also allow heat dissipation. I can see through the side slot, that the heat dissipation pillars dont crush the provided rubber heat dissipation pads at all - i didnt like the idea of the board being stressed by poor pillar design. The pillars are also at the correct height to match the height of the components they dissipate heat from.Extra rubber pads and screws are provided in the pack - really good of them considering how much of a faff it would be to get future replacements. The screws are light threaded, but then you arent fixing a shelf to a wall, merely securing the two sides of the case, so they shouldnt be overtightened anyway.I can also see the pi status leds through two small holes in the case.This case gives the pi a bit of mass so its not as easy to knock around on a desktop for example.I also love the heavy ribbed design.My pi is currently headless, so i dont yet have the ability to do extensive thermal testing.the ports are also all well exposed - none sit within the case too much.Very pleased.

Solid metal case, fits the pi 3b perfectly. Comes with sticky pads to protect the board components and four allen screws that fit through the board and hold it all together, excellent quality.

The Geekworm P173 case is an all aluminium, solid weighty simple case that offers a passive cooling design.It seems well made and of good quality.Assembly was easy, the smaller thermal pads were a bit fiddly for my fat fingers so I needed to use plastic tweezers though. I used the copper shim on the processor since I had some thermal paste on hand.Everything lines up well and the case goes together nicely with the bolts.With the RPi4B running at 2.1GHz the temperature was 61⁰C under a full load for 30 minutes, a reduction of 10⁰C compared to the old case with a fan I was using.As this case uses passive cooling there's no annoying fan noise unlike my old case.A few negatives.The case doesn't have rubber feet sadly, so it does slide around on the desk etc. Easy enough to put some on, but would of been nice if they were included.Probably due to the case being all aluminium it appears to reduce wireless performance a little, my bluetooth keyboard occasionally lags or the have the occasional key repeat which never happened with my old plastic case.

I have a similar case to this one but this one seems chunkier and heavier which is ideal. I didnt want any fan on this one and I think this case will provide enough area and fins to get rid of the heat. Without being crazy about it, its hard to see what else anyone can do more to get rid of the heat without using a fan.The board fits in perfectly as do all of the connector holes. The two halves fit perfectly too with a near invisible join. It comes with a set of heat pads to connect the CPU & chips to the case. Personally I find these easy to fit but people seem to have trouble with them. You take off one side peel plastic then fit to chip then peel off the other side using tweezers. Dont try to do both before fitting.Not much else to say. Its has slots in the side for the ribbon cable access to IO pins or camera / DVI ports and even a couple of small holes to see the status LEDs.If I didnt need to have easy access to IO pins then I would buy this one again as a first choice. If you need easy access to IO pins then the other similar ones with the open IO area might be the better choice.

fits the pi4b perfectly as expected, lovely case, good heatsinking to the case, very robust for kicking around on my desk.
