This is my NAS project based on a Raspberry Pi (4 or 5) running openmediavault.

As this project is too complex as to describe here in a few lines how to build this NAS, you will find a comprehensive Instructable here: https://www.instructables.com/Raspberry-Pi-NAS/

These were my design goals for the enclosure:

Cabling

• Just only the power and network connectors should be accessible from the outside
• Both connectors are on the rear side and next to each other
• Avoid the 90 degree offset for power and network connectors which is typical for Raspberry Pi
• The USB connectors and cables must be all inside the case for a clean design

Printing

• There are only a few parts to print: the enclosure tray, device rack and side lid - optional: a stand
• Quick and easy printability is secondary to design - supports are mandatory for the enclosure tray
• A compact size which can be printed on a 200x200mm printer - no large format printer required
• Durable connections - melt-in brass threaded inserts instead of printed threads or clips

Miscellaneous

• Must be suitable for both Raspberry Pi models 4 and 5
• No active cooling for noise reduction (0dB noise emission with SSD) @idle: 55°C CPU / 40°C SSD
• Meaningful multi-line display instead of simple status LEDs
• The display brightness will be reduced at night
• Cheap and easily available standard components
