Argon ONE case for the Raspberry Pi 4 – a quick review

Hi everybody. I bought this case the other day for my media centre Raspberry Pi running downstairs in the lounge. The previous case (one of those all-metal all-heatsink jobbies) looked a bit out-of-place, so I decided to go for the Argon ONE as I’d heard a lot about it. TL;DR – just buy it if you want a brilliant case for your Pi.

At £25, this is one of the more expensive cases you can buy, but I was very impressed. It comes well-wrapped in a cardboard box and consists of:

  • The main body of the case (metal) including a fan
  • The bottom plate (plastic)
  • A daughter board PCB
  • Heat transferrance pads
  • Screws to hole it together

All of the parts are very well-made/moulded – you can see and feel the reason why it is more expensive than other cases.

Assembly is simple. You plug the daughter board into the Pi’s HDMI and audio ports – this brings all the ports you associate with the Pi round to one side of the case. You apply the heat transferrance pads to the Raspberry Pi (thus allowing the whole of the top of the case, which is metal, to act as a heatsink).

The assembly (Pi plus board) then plugs into a GPIO header inside the main body of the case. You use the included screws to make sure it is firmly held in place (although, frankly, the Pi is tight enough that you don’t need to bother!) and then the bottom plate is screwed on using a different set of screws.

Once assembled, you can immediately see the special features of the case. All the ports are on the ‘back side’ as well as a power button. This button can be programmed to do different functions and you can download a script from the Argon site that will program it to safely shutdown the Pi.

Another feature that I haven’t mentioned in full is that there is a small 5V fan inside the case which will cool the Pi 4 down. There are plenty of vent holes in the case, so overheating should not be a problem. A script, which is downloadable, controls the fan speed depending on CPU temperature.

The final special feature is quite brilliant. You might think from the first picture that this is a ‘sealed unit’ useful only for media centres. You would be wrong. Full access to the GPIO pins is available by lifting off a metal plate which is magnetically held in place:

The ports are all labelled and, to add to the joy, the exposed GPIO pins are colour-coded to aid in pin-navigation! It really is a lovely feature which means that you can use it as a hacking platform as well as a “nice box to hold your media center Pi in”.


I thoroughly recommend this case if you can afford it. It is solid, well-made and has a host of features that are difficult to beat.

You can buy the case from The Pi Hut for £25 plus postage. (As of 23/4, it is sold out, but Jamie at the Hut says that they are getting hundreds in very soon!)

  1. This looks like The Case to have and finally a case that has an on/off/shutdown button…a feature missing from just about all Pi Cases.

    I will certainly buy one — at the moment, the case appears to be out of stock but one can get notification when available.

  2. Totally agree with you. I found mine was a little fiddly fitting the metal top to the plastic base, but well worth the effort. A lovely piece of kit. The SD Card is accessible at the front of the case.

  3. I have one and had issues with two of the boards being quite “fiddly”. The board which plugs into the GPIO connector, didn’t supply power to the Pi but the Argon40 replaced that with a working board.

    The other board, which connects to audio and the 2 HDMI ports was glitchy. When I had the components out of the case, it all worked, but when I put it all in the case, there was no video. It took 2 replacement audio-video boards from Argon40 before I had a working case. Since then, no issues.

    I really like the case, but if I there are QA issues with these cases, or I knew I’d have to wait extra weeks to get a working case, I’d likely go for something from a different manufacturer. Argon40 told me my experience was not their normal, but I can neither confirm, nor deny what their actual customer experience is.

    • Interesting to get that feedback. Thanks John. I didn’t have a problem so couldn’t report any. Hopefully it doesn’t affect too many people!

    Well, the case finally arrived and it is a very handsome case indeed.
    BUT just one thing, I have found that I need an USB WiFi stick to get any WiFi connections. It would appear that the internal WiFi antenna is not working when the RPi 4 is totally enclosed in the case.

    Anyone else with this problem??

    All the best
