I’ve no intention of purchasing this case to test the new version, but I’m pleased that it now exists. This addresses the issue with the mirrored GPIO pins. Update 21 October 2021: Cooler Master have released a revised version of this case without, the Pi-Case-40-v2.

The instructions also suggest you could use a couple of the mounts to wall mount the case. Inside the box, you’ll find the case, along with 4 bolts and an Allen key to secure the case together, 2 thermal pads (nice to see a spare included) and 4 plastic wings which can be added to the case so that it can be attached using the standard VESA mounting system (75×75 or 100×100). Under a lift up section is printed a QR code which takes you to the Cooler Master Pi CASE 40 product page, where you’ll also find the download instructions for the software along with some accessories which can be 3D printed. DesignThe Cooler Master Pi CASE 40 arrived in a neat cardboard box, with clear assembly instructions printed on the inside surfaces of the box, avoiding the need for an extra printed instruction booklet, clearly, some thought was given to minimising waste. I’ve mixed feelings about the TPU bumper, but more on that later.My testing has shown that this case shows promise, but it’s let down firstly by a fundamental design issue and secondly by the software made available with the case.

I did find the bumper didn’t sit right around the USB ports, bowing out slightly (which you might be able to see in the image above), but I doubt many other people would notice. The TPU bumper is attached fairly securely to the case though 14 moulded mounting points that protrude out and interface at the joints between the aluminium and plastic sections of the case. The bumper on the top of the case is where you’ll also find the “re-mappable power button”. This flap covering the GPIO is quite stiff and a little awkward to use.

CaseWith the three cases fully dismantled and weighed, some surprises are revealed. For the Argon NEO, this meant removing the Pi and the plastic base, for the FLRIC I removed the Pi and the plastic base and popped off the top plastic top cover, for the Pi CASE 40 I removed the Pi, the plastic base the TPU bumper and removed the board which relocated the GPIO and adds the power button. It’s unclear if having a TPU bumper around portions of the case will hamper heat dissipation.Weighing the case and some competitors, firstly fully setup including a Raspberry Pi installed, then with all just the metal components of the case. Unlike the Argon NEO, it doesn’t heatsink the memory chip, which is reasonable, as I’ve not seen any issue with memory temperature being a problem, even in overclocked tests. The aluminium top case shell has a raised section to mate with the Pi processor, similar to that used in larger Argon ONE, though with extra ridges that run on the inside of the case and further increase the surface area and help with heat dissipation.

The Argon NEO accomplished this with a two-piece top shell design. GPIO AccessMaintaining access to GPIO pins is a challenge for all case designs, with several cases not providing access at all. Given the lid section is only attached to the base plate via magnets, the thermal transfer won’t be as good as the one-piece design of the Cooler Master Pi CASE 40 aluminium top section.With the total mass and heat sink design, the Cooler Master Pi CASE 40 should do well in the thermal testing. The Argon NEO weighs in the same as the Cooler Master Pi CASE 40, that is until you remove the top lid, when it then loses 50% of its weight. Probably in large part to the design using a hollow section to interface to the processor, rather than a solid block.

Pi Case 40 is not compatible with devices that only require direct connection to part or the entire GPIO of the Raspberry Pi with traditional layout. For example, the 5V and 3.3V pins are swapped positions!If you read the website carefully you’ll find the following note:“NOTE: Side access to the GPIO only allows the use of jumper cables. This makes it all too easy for someone to mistakenly wire connections to wrong pins, some with likely fatal (to the attached component) consequences. For reasons I can’t understand, and can only put down to the incompetence of the designer, the board results in mirroring the pin rows of the standard Raspberry Pi GPIO header. The board in my case is labelled “C2146-01-SJ”, this includes a surface mount 40 pin socket on one side and a right angle 40 pin through-hole header (along with the power button) on the other.

I honestly can’t understand how a product pitched as “The travel case of Pi enthusiasts, by Pi enthusiasts”, could have been released with this flaw. Wonky, difficult to read label for mirrored GPIO pinoutI think Cooler Master should quickly look to replace the daughterboard with a fixed design that doesn’t mirror the pins. The text in the image below is a lot clearer due to the lighting than it is normally. The label isn’t applied straight and level on my case, nor on the case used for product images on the Cooler Master website. This black on grey is hard to read, hindered further by the reflective clear tape it’s printed on. Not only does it make it incompatible with any Pi HAT, but it’s likely people won’t notice until it’s too late and they’ve caused damage.The case does feature a pinout label, however unlike the clear white on grey text printed directly on the case shown in the Kickstarter prototype images (and used on the Argon NEO), instead there is a clear label with black text stuck on to the side of the case.

GPIO3 is used to enable the “Wake from Halt” capability, which enables the button to be pressed to boot a pi that has been halted, rather than needing to cycle the power to the Pi. Re-Mappable Power ButtonThe Cooler Master Pi CASE 40 “includes a button that shortens pin 5 and 6 when pressed (GPIO3 and GND)”, the wording could be improved, such as the button pulls pin 5 (GPIO3) low when pressed. Instead, the community have stepped with a new header you can get manufactured: but this really should be necessary.
