The Odroid C4 case is an effective solution for those that are looking for a case that can both protect and also be mounted in space-friendly locations..
The case features localised cut-outs for the MicroSD, the USB ports, an Ethernet port, HDMI, an Audio Jack, IR sensor, and the GPIO Ribbon (and optional Din Rail clamp). Both sections of the unit are made from aluminium, with extended vents for air movement that are further complimented by an all-Black finish.
There is a fan attached to the case, where we would recommend this can be connected to the C4 board's GPIO pins 4 and 6 (Red connection to Pin 4 and Black connection to Pin 6) as shown in the image below:
