Summary

This is the version 4.1 of my Raspberry Pi NAS enclosure. This version is designed to use with 1 x 2.5inch HDD as main storage (and connect to the Pi through USB pins directly soldered to the main board). See the 4.0 version if you don't want an HDD attached and use USB drive as main storage.

The back plate is design to work with both Pi 3B+ and Pi 4 if you wonder.
