Modular Mini-ITX NAS Server Case by Nibb31

This is a modular computer case designed to build a NAS, a server, or a standalone mini-ITX desktop computer. You can stack modules on top of each other, so there is no physical limit to the number of hard drives that you can handle.

The model with the MB Module and either the Dual HDD Module or the PSU HDD Module is a 205x205x205mm cube. The model with an MB Module and a Single HDD Module is only 205x205x135mm

This case is not designed to accommodate GPUs or additional PCI boards at this time. However, you can use the template module to create your own modules for other purposes.

To assemble the case, you must use M3 hex screws of various lengths and M3 brass inserts:

Motherboard module

A mini-ITX motherboard motherboard which has side panels that are either full, or vented. The vented panels have screw holes to mount optional fans.

Important: Add four M3 inserts into the holes on top of the pillars of the chassis module before assembly

Mounting Frames

The case is designed around one or several universal HDD mounting frames. Each pair of these mounting frames can host a maximum combination of:

• Two full size 3.5" drives + two low profile 2.5" drives, or
• Four dual height 2.5" drives + two low profile 2.5" drives.

HDD Modules

The HDD mounting frames can be mounted into a choice of three types of drive modules:

• Single HDD Module: This module takes a single pair of mounting frames (mounted horizontally) and up to three 60 mm fans.
• Dual HDD Module: This module takes two pairs of mounting frames (mounted vertically) and a 120 mm fan.
• PSU HDD Module: This module takes a single pair of mounting frames (mounted vertically), a single 120 mm fan, and a standard ATX power supply

For example, the Dual HDD Module can house up to twelve 2.5" drives, or four 3.5" drives plus four 2.5" drives!

The motherboard module has side panels that are either full, vented, or with a hole for a 12V 5.5 mm (5521) jack. The vented panels have screw holes to mount optional 40 mm fans.

You can stack multiple HDD mounting frames on top of each other.

Important: Add four M3 inserts into the holes on top of the pillars of each chassis module before assembly

Top cover

The top cover is designed to fit to each of the modules. You can also fit some optional handles for transport

Template module

I have attached the Fusion 360 source file for designing your own modules for this case. With this, you could include routers, a custom PSU, a PCI extension rack, etc...
