QNAS FRAMEWORK V1 Open-Source NAS Adaptable ITX Motherboard

QNAS FRAMEWORK V1

An open-source NAS framework compatible with ITX motherboards

2025.5.2

Added a hard drive power adapter STL

For powering hard drives independently using a 12V power adapter, replacing the FLEX power supply

This module requires two M2 screws (heat-melt nuts are M2*3*3) to secure it to the adapter plate

The adapter plate is secured to the original power supply location using three M3 screws

Simultaneously, the motherboard can utilize more affordable thin ITX motherboards (around 300 yuan)

This hard drive power module includes a sync cable, allowing for simultaneous startup and shutdown with the motherboard

2025.4.25 Update

Added two STLs: a separate base and a separate front panel

After separation, three M3 screws are required to connect the two parts

The purpose of the separation is to allow for the shipment of individual components, reducing package size and shipping costs

2025.4.24 Update

Added a chassis with two STL models, increasing the PCIe opening area

To avoid interference with the output port of certain network cards

2025.4.18 Update

Added a fan mount STL file for installing a 20cm fan on top for overall NAS cooling

The cooling effect has been tested, and with a room temperature of 25 degrees, the hard drive temperature is suppressed to around 30 degrees

The fan used is an aerocool 20cm chassis fan, slowed down to approximately 500 RPM using a speed reduction cable for silent operation

2025.4.16 Update

Added a column with two STL files to accommodate a 170MM tall FLEX modular power supply

Compatibility Scheme: (This is the initial scheme, future updates will enhance compatibility)

ITX Motherboard 17*17CM

FLEX Power Supply or 12V DC Power Supply with hard drive power module

Four 3.5-inch HDD hard drives

Two 2.5-inch 7MM SSD hard drives

Half-height expansion card for expanding network cards or hard drive cards

20CM fan position at the top of the chassis

Uses a 16MM circular computer power switch

FLEX Power Supply Noise Reduction Scheme:

Purchase a high-quality 12V 0.05A 0.6W 4020 fan, 2PIN, to replace the original fan

A resistor can be connected in series with the red power wire (12V positive) of the fan to further reduce speed

Because the fan's reduced speed prevents effective negative pressure airflow, the fan's direction should be reversed to blow air into the power supply

Printing Instructions

Original color scheme is gray, white, and bright green

Support is required for the recessed areas on the side panels If you have an AMS, it is recommended to use a dedicated support material, significantly reducing support removal difficulty

A flat metal pry bar can be used for support removal

Use fast-drying adhesive to secure the green decorative pieces Ensure the bonding surfaces of the side panels are completely clean before applying adhesive

It is recommended to use ABS or PETG for printing
