If you are shopping for a NAS case, our review of the ten best computer cases for network access storage will provide you with all the information you need to make an informed decision. Keep reading to find out more.

What Is The Purpose Of NAS?

Network Access Storage (NAS) is a device that stores data over a network. NAS devices are usually connected to the network via an Ethernet cable powered either by AC or DC power. They are accessible by other computers on the same network, making them an ideal storage solution for small businesses.

You can configure a NAS device to share files with all computers on the same network or with specific computers on the same network. It is also possible to set up a NAS device to share files only with computers outside of the local area network (LAN).

If you’re on a tight budget and looking to connect your storage to your local network, converting an old PC into a NAS (Network Attached Storage) can be a cost-effective solution.”

How to Choose the Right NAS Case Device?

Choosing the right NAS device is essential to ensure data integrity, security, and accessibility. Many factors need consideration before making a purchase. Each NAS device has its own strengths and weaknesses.

For example, some NAS devices have a lot of storage capacity while others have a lot of processing power. You should consider what your NAS device needs to do for the best fit. Let us look at some of the factors that will influence your choice of a NAS computer case:

Storage Capacity

NAS is a network-attached storage device typically used to store large volumes of data. Its storage capacity determines how much data you can store and how fast you can access it. A larger storage capacity means more data can be stored, which means faster access to this information when needed.

Processor, Controllers, and Memory

Smaller NAS systems do not have the storage capacity or processing power of larger ones and will slow down when used heavily. Some backup solutions allow you to avoid deduplication encryption altogether, so this might be an option if you have these needs. Meanwhile, arger NAS systems will usually offer multiple storage controllers for faster performance and enhanced capabilities.

Network and Connections

NAS Network and Connections are the backbone of NAS performance. The higher the bandwidth, the faster data is transferred between devices. To achieve high performance, you should connect the NAS device to a network that can provide enough bandwidth for data transfer.

Populated or Diskless?

A populated NAS is a device that comes with hard disks installed, while a diskless NAS is a device without any hard disks. Populated NAS devices are more expensive as they come with pre-installed hard disks. However, they offer greater storage capacity and are easier to set up. On the other hand, diskless NAS devices are cheaper and easier to set up but have lower storage capacity.

Caching and Hybrid Drive Features

Caching is a technique that stores the most frequently accessed data in fast, local memory. This way, if the data is requested again, it can be retrieved from the cache instead of being read from slower storage. Hybrid drives combine the benefits of both traditional hard drives and solid-state drives.

The latter are more expensive but offer faster access to data and less wear and tear on moving mechanical parts. The two features affect NAS performance because they ensure that users can work with more significant amounts of data faster while reducing power consumption and system costs.

Operating System

The NAS operating system is the software that runs on the NAS. It manages the day-to-day operations of the NAS, and makes it easier for you to access and share your data. It can be a good idea to use a third-party operating system like FreeNAS, because it offers more flexibility in terms of configuration options than an embedded OS.

What are the 10 Bes Nas Cases For Servers

Now that you already know what features to consider when choosing a NAS pc case, here are the best computer cases for NAS.

for Compact DIY Storage Builds

Jonsbo N2

EDITORS’ CHOICE★★★★★ 4.5 Outstanding

Pros & Cons

  • Fast performance
  • Goood
  • Expensive
  • Bad

Jonsbo N2 NAS case model is the most compact option in the market with premium features including hot-swap capability, dense storage configuration, and premium construction in an internal volume space of only 11.1 liters. This case is intended for builders that have experience with computer construction and prefer compactness and space efficiency.

What Sets the Jonsbo N2 Apart?
The backplane for the N2 model supports five 3.5″ hot-swappable drives, and one 2.5” SSD. Everything fits in an ultra-compact form architecture of Mini-ITX. Tools for drives and other equipment in the intro have been eliminated thanks to the magnetic front panel that allows for no-contact swaps. This is a differentiated feature of Jonsbo N2 NAS case model and allowed for improved handling of temperature due to the improved isolation of the drives from the CPU and other components.

The backplate minimal spin-up support means that most drives at once may require a powerful SFX power supply for stability.
How Does Cooling Perform?
The N2 ship with basic system cooling. The system comes with a 120x15mm rear exhaust fan installed that may cause excessive system cooling noise. Builders report improving the BIOS fan control noise from the system to improve the noise produced my the fan. Negative system pressure is the main form of active cooling with hot air exhausted from the rear and a mesh airflow grate is the only form of cooling for rapid passive air movement. Systems with multiple 7200 RPM drives installed may experience rapid cooling increase.
What Are the Compatibility Constraints?
Due to the space being restricted, there are some compatibility constraints. The height limit for the CPU cooler, not including the tower coolers, is 65mm. There is also a single-slot PCIe card height limit of 197mm low-profile. This further restricts expansion. A standard provision for most Mini-ITX boards are four SATA ports. Therefore, builders regularly install M.2-to-SATA adapters or miniature HBAs to fill all six drive slots.
What’s the Build Experience Like?
The internal layout requires some planning as the arrangement and fit of the components is quite specific. Pre-wiring the power supply unit is essential because of the low clearance. The top panel is secured with Allen screws, and cable management, most especially for the front I/O, becomes difficult. To avoid interference with the fan and improve fit, a lot of users advise the use of right-angle SATA cables.
Who Is the Jonsbo N2 Best For?
The N2 competes with ease-of-use within the NAS builders markets. Some users value the minimal footprint, hot-swap support, and sleek external touch. Compared to the N3, or Froctal Node 304 that is larger and has better cooling, it is engraved with the N2s characteristics. This is also used with Plex and TrueNAS or Jellyfin for users that want to Synology systems but with more flexibility at the cost of ease-of-use.

Ultra-Compact NAS and Gaming Cases

Jonsbo N10 & NV10

EDITORS’ CHOICE★★★★★ 4.5 Outstanding

Pros & Cons

  • Fast performance
  • Expensive

The Jonsbo N10 and NV10 are compact 4.5L Mini-ITX enclosures (205×205×108 mm), sharing the same external shell but serving different purposes. The N10 is optimized for SSD-based NAS setups, while the NV10 targets low-profile gaming builds.

The N10 supports 4× 2.5″ SSDs/HDDs, mounted in a built-in cage. It lacks a hot-swap backplane, so every drive needs direct SATA and power connections—tight in such a small footprint. Dual 40mm exhaust fans provide basic airflow, suitable for low-TDP platforms like the Intel N355. Passive airflow remains a limitation for high-heat components like 10GbE cards or NVMe drives. Modders have managed to fit 2× 3.5″ drives, but only if under 8TB due to clearance issues.

The NV10 removes drive bays to fit dual-slot low-profile GPUs, supporting cards like the RTX 4060 LP or 5060 LP, and includes a PCIe 4.0 riser. It handles CPUs up to 65W TDP (e.g., Ryzen 7600X), though thermal limits show during stress tests—CPU at 85°C, GPU at 88°C. Builders often 3D-print custom brackets to add exhaust fans over the GPU zone to improve thermals.

Both cases require modular FLEX ATX PSUs (≤150mm), with common picks being Overtech 600W or Appa 500W. The removable motherboard tray simplifies installation, but builders should install rear-facing M.2 SSDs before assembly due to access limitations post-build.

What About Build Quality and Design?
Both models feature 3.3mm aluminum panels, USB-C front I/O, and a wooden accent for premium aesthetics. At ~$82 for the N10 and ~$65 for the NV10, they offer strong value for their quality—but demand precise hardware selection.
Who Should Use These Cases?
N10: For users needing a silent, SSD-based NAS with limited drive space.
NV10: For gamers seeking a portable 1080p rig in a sub-5L form factor.

Each case performs exceptionally when paired with the right components, but neither tolerates poor thermal or spatial planning.

How Much Storage Does the Node 804 Support?
The Node 804 supports up to 12× 3.5” HDDs and 4× 2.5” SSDs across its various mounting points. Despite the high capacity, it doesn’t include a drive backplane, so each drive requires separate SATA data and power cables. This can result in cable clutter, especially in fully populated builds.
How Is Cooling Managed?
The dual-chamber design separates the CPU/GPU side from the PSU/drive side. Each chamber has its own airflow path and filtered intakes. While airflow is generally strong, enterprise-class 7200 RPM drives can reach over 40°C under load, especially if fan placement isn’t optimized. Builders often upgrade to high static pressure fans and use compact PSUs to improve airflow around the drives.
Support
The case supports micro-ATX and Mini-ITX motherboards and allows full-length GPUs, HBA cards, or 10GbE NICs with no depth restrictions. This makes it a strong option for Plex transcoding, ZFS storage pools, or VM hosting.
Are There Any Build Challenges?
Drive swaps can be time-consuming, often requiring removal of drive cages. Cable management is tight, especially in the PSU chamber, where modular or short cable PSUs are preferred. The lack of hot-swap trays and the use of standard screws add to the setup time but not to long-term reliability.
Who Should Use the Node 804?
The Node 804 is ideal for builders who prioritize storage capacity, cooling control, and expandability over modern conveniences. It’s a proven choice for DIY NAS, home labs, and media servers, especially for users comfortable with internal cable routing and hardware planning.
