Good info. Thanks.

I too bought a 3rd party 5v@3Amp PSU with an in-line on/off switch for the RPi4 but it died on me a couple of years ago. The funny thing was, it was more expensive than the official Raspberry Pi PSU to buy. So, since then I have stuck with using the official PSUs and have had zero problems.

[EDIT] I had a Flirc case for the RPi3 and wasn't impressed with its passive cooling capabilities, so I went pack to active cooling with a fan+heatsink which was much better. I haven't tried the Argon case (mainly due to the price) but it has some very good reviews.

Thank you, nice to be able to add a cheaper solution that works.

I don't have hard data to provide, sorry. I didn't anticipate this request when I made the recommendation post.

The RPi4 I have is currently inside my version of this build: https://back7.co/home/raspberry-pi-quick-kit-one which I built about a year ago. The passive cooling aluminum case was incompatible with that build so the RPi4 is without it.

I bought this passive cooling aluminum case for a photography project before I commandeered the RPi4 to build Back7's Raspberry Pi Quick Kit One with. I enjoyed the compact size of this case and it did a good job of protecting RPi4 on both sides. During the testing of the passive cooling aluminum case, I do remembered coming away impressed with the huge temperature drops and the RPi4 didn't stalled through the apt upgrades like it did in the original Raspberry Pi plastic case. That was good enough for me.

Something worth mentioning: it is required that I take the case apart if I want to install ribbons to or remove from the DSI and camera ports, which was an issue with the thermal stickers if I did this too many time.

Maybe you guys might find this interesting. My search for passive cooling cases was indirectly inspired by this: https://www.raspberrypi.org/blog/astro-pi-flight-case/ I figured if that's good enough for NASA/ESA, then the $18 aluminum case is more than good enough for me.

For sure, it's a beautiful looking futuristic design that wouldn't look out of place on Luke Skywalker's X-wing fighter or Doc's Delorean car from the Back To The Future movie. I've also seen the 3D-Printed Astro Pi flight case which, being made of plastic, is intended for aesthetics only. Definitely more suitable for art lovers and astronauts than practical use.

you can find some cases here too: https://geekworm.com/collections/ras...onstraint=case
and another solution: https://www.the-diy-life.com/water-c...retty-awesome/, https://www.instructables.com/Water-...-Pi-4-Cluster/
And a test: https://www.the-diy-life.com/thermal...ling-worth-it/

By the way, in the outer space you do not need cooler at all (I guess would be better to use a heater because the device does not work reliably at 4K).

For my test and development RPi4 I don't have a case/enclosure. It's mounted on a block of wood with stand-offs on a sheet of perspex, supported by rubber inlets at the base stand-offs to eliminate any vibrations, etc. It offers easy access for any and all add-ons; sd cards - USB devices - etc., is easily dismantled and rebuilt, and is very quiet - the only noise is the airflow from the fan which is hardly noticable. It also has felt pads under the wood block base to further eliminate any transfer of noise. This is the best setup I have worked with for a test machine and I'll probably keep it indefinitely.

I see you've found the link that I used to built my copy of Astropi with. Yes, it has the 'cool' factor, but it was an educational experience, too. That was my reason for getting into it. I had one printed up. This was a few years ago. This one project opened up a bunch of new worlds for me. It was my first 3D-printed object and introduced me to the world of 3D-printing. I even bought a 3D printer afterward. It was the first time I learned how to solder and wire up push buttons to a Raspberry Pi and get them working. That skill alone has spawned a few other projects and addons I would not have taken on without. The Sensor hat has a tiny joystick on it so I learned to program it to play a basic game on the LED matrix on the Sensor hat (it was the classic Snake game). I've never done that kind of programming before. First time learning to program in Python and I gained more new understanding of Bash scripting. There were many other firsts for me that I won't list here. The 3D-printed Astropi case needs a GPS and RTC boards but now I know how to add that. The Astropi has the RPi3 inside so overheating wasn't much of an issue. There was a webpage where another company was selling an aluminum Astropi case clone but that's gone today. Boy, did that one looked good! Any STEM teachers or anyone who want to take on electronics and programming ought to take note of the ESA's Astropi project and especially the Sensor hat. Astropi is such a good starting point that covered a wide span of skills and understandings.

Your setup looks good! Do you plan to varnish your wood base? Drill a hole in the middle of the acrylic plate and pop an addressable RGB LED (or a few) in that hole so it'll light the acrylic plate up, too. You could even tie in the addressable RGB LED(s) to your RPi's CPU usage or its temperature.

Pan64, sorry, but it was never meant for operations outside of the International Space Station. Please use your search engine to search for 'astropi ISS' and hit the Images tab to see it in action. There are two of them (one with visible camera, one with infrared camera) and they are still up in the station today. With sharp eyes, one can find them in the background of the live tv feeds and press image/video releases from ISS. Thanks for sharing your links. One of your links had a few passive cooling aluminum cases in it that I was not previously aware of. The water coolant links were interesting read!

My RPi4 test setup is entirely for functional and practical purposes/reasons. The less time I spend dismantling a case to plug something in, the better. This setup affords me instant and continual free access in all areas. Very frequently, I need to quickly swap sd cards or other storage drives, USB devices, RTCs or other plug-in modules, and a whole load of other things. I'm also using the GPIO pins a lot in some situations. Having an open and accessible working environment is just easier. I don't have any plans to modify the current setup. If/when the RPi5 is released I'll replace the current RPi4 test machine and put it into a Cyntech case and hang it on the wall with the other build systems.

Cases and cooling solutions are a personal choice. I'm not a pan of passive cooling, as I prefer smaller and compact fans/heatinks. I think water cooling on the Raspberry Pi is for those who have more money and time to waste than common sense. lol

I use a Flirc aluminum case on my Pi 4. For my purposes, which is mostly audio/video streaming and some light web surfing, the Flirc case is quite adequate, and the less fan noise I can hear the better. I use an old PSU fan for additional cooling on the rare occasion the pi starts heating excessively.

Looks cool!
I've just finished developing some work on the Slackware Installer for the RPi4. You'll be able to have Slackware on it soon! :-)

I read your Tweet about RPi4 integration. Good work. How far off are you from releasing Slackware AArch64 in terms of a timeframe? Any rough estimates/guesstimate/predictions you can give us?

We all know that, when it's ready.
