The design of the CamdenBoss Cube Raspberry Pi 4 case is certainly very different from the usual small rectangular cases typically used. When I first saw it, it reminded me of the Borg Cube ship from Star Trek. Though the intricate pipes of the Borg ship are clearly for a practical reason, the CamdenBoss Cube appears to be purely aesthetic.
The case feels solid when fully assembled. When in two pieces the plastic feels rigid with nicely rounded edges.
- 4 x 7mm plastic standoffs with brass inserts provide mounting points for the Raspberry Pi 4. 4 cross-head screws are provided to secure the Pi (annoyingly non-magnetic).
- 2 x T10 security Torx bolts secure the two halves of the case after they slide together.
- The case was supplied with 4 large rubber feet.
- The case lacks any form of ventilation or fan mounting.
- The main connectors on the Raspberry Pi are accessible. Though there aren’t any slots to provide access to the GPIO.
- The SD card is accessible at the rear of the case next to a small opening to show the Pi’s status lights.
- The large unstructured space doesn’t appear to serve a purpose, except for an aesthetic one. The extra height could have been used for Pi HATs, however, without access to any ports typically found on HATs this isn’t likely to be practical.
Testing is once again performed using Stressberry in a series of 1hour tests at 25%, 50%, 75% and 100% load. During testing the Pi is temperature is monitored, along with the ambient temperature. In addition, the core clock speed of the Raspberry Pi 4 is tracked to measure any impact of thermal throttling.
The extra volume of air in the Cube case does appear to help to avoid thermal throttling until the load reached 75% where the Pi starts to throttle regularly to 1000MHz. The full load 4 core test sees it dropping to 1000MHz and throttling further to 750MHz frequently with one measurement dropping to 600MHz whilst under load.
This Raspberry Pi 4 case is certainly more about a design aesthetic than offering additional functionality. I’d have liked to have seen the space used to provide more functionality. For example:
- A mounting point for an SSD/HDD and suitable SATA interface card.
- Provide a large fan mount to allow a low RPM fan to be installed to improve cooling.
- Design specific variation of the case tailored to common Pi HATs.
That being said, the large space in this well-constructed case could provide a starting point for Pi-based projects.
CamdenBoss provide custom print and cutting services, so this case is more a foundation for a prototype. Perhaps where makers are happy to drill and cut the case to tailor it to their needs initially, before finalising a design in collaboration with CamdenBoss. It would be nice to see some examples of custom versions of this case on their website, to get a better feel for what is possible and practical
