I have designed a NAS which has been in use for over a year now. The case has massive airflow due to the large Noctua fan. There is space for two 3.5" hard drives, currently 2x 2TB WD RED are installed. For easy maintenance, the HDD caddies are quickly removable. The case has an attached lid.

Thanks to the directly connected Gigabit LAN of the RaspberryPi 4 and a Gigabit Internet line I can use the speed to the full. We use the NAS location-independent with 5 people who all synchronize live on the NAS.

Since everything is pretty custom I will release my fusion files. So ignore the stl, it's only for visualisation.

I am happy about donations, the design has taken a lot of time :-)

Stuff used:

• Raspberry Pi 4 B (4GB RAM)
• GOOBAY 77554 Lan Extension
• USB Extension
• DELOCK 84230
• M2596S DCDC
• Noctua NF-A14 ULN
• ASM1153E USB3 to MSATA
• MSATA to SATA adapter
• Meanwell 12v Power Supply
• ...

The caddy is not from me. Thanks squirtle_93 for that thing. https://www.thingiverse.com/thing:4106276
