We already have many cases for Raspberry Pi SBC’s. Besides the official one, we already have third-party enclosures such as a KKSB compact fanless metal case for Raspberry Pi 4, Argon One enclosure brings all ports from the SBC to the side, as well as a variant for M.2 SSD’s, and even DIN rail enclosures.
But here are more options as INUX3D, a design studio and 3D printing facility based in Slovakia, decided to create its own 3D printed modular case system for Raspberry Pi. The TerraPi module enclosure system supports passive and active cooling, up to two 2.5-inch SSD’s or HDD’s, as well as horizontal or vertical mounting, and there’s also a DIN rail option.
Apart from the fanless model targeting uniquely the Raspberry Pi 4 SBC, all TerraPi enclosures also work with Raspberry Pi 3 B/B+ models and are especially suited for people wanting to use the board as a NAS Server, surveillance station, or even a web server. The company highlights Open Media Vault (OMV) open-source project that can make good use of one or two drives.
Note that most of the kits do NOT come with a USB to SATA adapter, and those need to be purchased separately. They can easily be found on Amazon or Aliexpress. INUX3D currently offers eight different TerraPi enclosures in its store with pricing ranging from 4.99 Euros for a vertical mount case without SSD support, and up to 24.99 Euros for a vertical mount, fanless kit that supports two SSDs.
