Orange PI Zero NAS

As I wrote in another thing (https://www.thingiverse.com/thing:2584248), I did like the original design quite much so I decided to stick to it in other projects.
In a recent shopping spree at Aliexpress, I aquired an OrangePI Zero NAS expansion board which basically adds a SATA port, two USBs and an mSATA slot to the OrangePI Zero. One shouldn't expect too much performance-wise since the SATA and mSATA are still connected to the OrangePI's USB2 ports. It makes however for a nice little fileserver e.g. as a backup for an existing NAS. OpenMediaVault 3 runs quite well on it.
In order to build this you would need:
-OrangePI Zero original (the one with the H2+ processor and 100MBit Ethernet, the "plus" version is still quite beta)
-OrangePI Zero NAS expansion board
-At least 8GB uSDHC (the faster and bigger, the better)
-mSATA drive if desired
-2.5" SATA drive if desired (would need an additional SATA/Power cable)
-Case mount uUSB socket with cable and uUSB plug
-Case mount USB A socket w/cable and USB A plug
-3mm LED w/ resistor and mount,
-USB A plug w/ solder connectors
-15x15mm or 20x20mm heat sink with adhesive pad
-20mm Fan (REALLY necessary !)
-3mm light conducting plastic fiber (for the OrangePI's status LEDs)
-3mm screws and nuts

Assembly should be quite easy:
-Screw in the fan first
-The lower USB hole is for the "A" connector. Screw that in
-Add the mSATA to the NAS board
-Put the heat sink on the OrangePI, connect the PI to the NAS board
-Screw in the whole assembly
-If a SATA drive is used, connect the cable to the drive and mount the drive to the case
-Mount the uUSB above the SATA drive
-Connect the uUSB to the OrangePI
-Connect the USB A to the NAS board
-Connect the SATA and Power cables to the NAS board
-Cut the light conducting plastic so it ends flush at the front and overlaps the OrangePI's LEDs
-Chamfer the LED-ends ot the light conducting plastic
-Put in the two pieces and fix their LED-ends with some hot glue over the respective LEDs
-Mount the 3mm LED
-Solder the LED w/ resistor (do NOT forget that one!) and the Fan to the USB plug and put that in
