This is the new version of my 2021 dual HDD NAS project.

What's new?

It is designed around the Raspberry pi 5:

• The ports configuration differs from the Raspi 4 so I made sure everything is perfectly aligned to be able to benefit from every connector available, including the SD card slot, so you can insert and pull out the card without opening the box.
• The Pi 5 has a built-in fan port and fan management for better cooling. The design takes advantage of that and you can attach a compatible fan that will help keep the electronics cool.
• The Pi5 features a power button to switch the board on and off. An integrated flexible button on the front side of the box gives you the opportunity to use it.

Also:

• The design is more robust. Assembly relies on brass inserts and M3 bolts. No more screwing into plastic. You can assemble and disassemble without fear of breaking or loosening the parts.
• The assembly itself Is much easier, as I spent a lot of time to make sure you can reach every necessary spot in the parts with a screw driver.
• I even thought of a special hole beneath the ethernet connector so you can unclip it without having to unattach the Raspberry Pi if necessary.

Parts list:

• PETG
• M3 stainless steel Hex Socket Head Cap screws: four M3x10mm to attach the fan to the cover, eight M3x6mm to attach the 2.5 SSD drives on the sides of the cradle, four M3x4mm to attach the Raspberry Pi 5 to the bottom of the cradle.
• Sixteen 5.7mm long with 4.6mm diameter base M3 brass threaded inserts: four for the Raspberry Pi, four for the fan, four for the feet (under the cradle), and six for the cover to attach it to the cradle.
• A Raspberry Pi 5
• two SATA Hard Disk Drives (you may use only one though)
• two very short SATA USB cables with thin connectors, I used a Sabrent model (Sabrent USB 3.0 to SATA cable)
• some heatsinks and a fan for the Pi (like this)
• one ethernet cable
• one power adapter. WARNING: the Raspberry Pi 5 can power the HDDs but only if you have a good 27W power adapter. Otherwise, you will encounter many malfunctions, such as one or both your disks not mounting or regularly "disappearing"...

Assembly

It's pretty simple if you respect the order. I made a video of the way you should assemble the parts here.

To be honest, the trickiest part of the assembly is when you have to "fold" the cables so they fit in the cradle and connect to the USB ports without ending up blocking the way for the ethernet cable. Be patient and cautious. I made it, so can you!
