Custom NAS case for 5 bay NAS using Mini-ITX board. There are some options visible on photos. You can build it very simple, without any design tuning and also you could have it naked without upper part case panels - It depents on your preference.
For better airflow it's recommended to build it with all parts.
Materials
If you need more airflow for bottom part (like me), You could drill holes which are then covered with PLA front grill.
