AI Verdict
This is a Mini-ITX NAS chassis with 8x 3.5-inch hot-swap bays and 2x 2.5-inch mounts, supporting SFX PSUs and 130mm CPU coolers.
This chassis is a strong fit for anyone building a high-capacity Mini-ITX NAS or home server. Its 8x 3.5-inch hot-swap bays and support for 130mm CPU coolers and 280mm GPUs make it capable for demanding storage and even some light compute tasks in a relatively compact footprint.
If you need more than two PCIe slots or support for an ATX power supply, look for a Micro-ATX or larger NAS-specific case.

Pros
- Accommodates 8x 3.5-inch hot-swap drives and 2x 2.5-inch drives for significant storage capacity.
- Features a USB 3.0 Type-A port and a USB 3.2 Gen 2 Type-C port on the front panel for modern connectivity.
- Includes two 100mm fans in the HDD compartment, maintaining drive temperatures under 40C at load.
- Offers ample clearance for CPU coolers up to 130mm tall and dual-width PCIe cards up to 280mm long.
- Constructed with a thick aluminum shell and sturdy metal frame, contributing to a solid build with no reported rattles.
- The front panel is magnetically attached, allowing for easy, tool-free access to the drive bays.
Cons
- The PSU mounting bracket requires a long Philips head screwdriver for removal, complicating installation.
- Drive installation relies on rubber grommets instead of caddies, making drives difficult to pull out and potentially damaging the grommets over time.
- The included 100mm fans are 3-pin, limiting granular speed control via motherboard PWM headers.
- Cable management can be a tight fit, especially around the PSU and CPU cooler area, impacting airflow.
- The case provides only one front button, requiring users to choose between power or reset functionality.
- The included instructions are described as 'questionable' and lack detailed configuration information.
Dimension Scores
The case offers 8x 3.5-inch hot-swap bays and 2x 2.5-inch mounts, providing exceptional storage density for its 233x262x298mm Mini-ITX footprint.
The included 100mm fans keep HDDs under 40C at reasonable sound levels, but they are 3-pin and can be loud if not speed-controlled via the motherboard.
Constructed from thick aluminum and steel, users report a solid build with good fit and finish, and no noticeable buzzes or rattles.
While there are provisions for tie-downs, the internal space can be a tight fit, especially around the SFX PSU, making clean cable routing challenging.
Best For
- DIY home server builds requiring 8+ 3.5-inch drives for network-attached storage.
- Compact Mini-ITX systems where high storage density is a priority.
- Users needing a dedicated server-grade hot-swap backplane for easy drive maintenance.
Not Recommended For
- Users requiring ATX power supply compatibility due to its SFX-only support.
- Builds needing multiple full-height PCIe expansion cards beyond the two available slots.
- Anyone prioritizing silent operation without replacing the included 3-pin fans.
Watch Out For
- The PSU bracket needs a long Philips head screwdriver to remove, which isn't a standard tool in every kit.
- Drive mounting uses rubber grommets instead of smooth caddies, making drives hard to extract and potentially chewing up the rubber over time.
- There's only one front button, so you have to decide if it's for power or reset, not both.
- The included fans are 3-pin, meaning you can't control their speed precisely with PWM, potentially leading to higher noise if not managed.
- Cable routing can be cramped, especially around the PSU, which might restrict airflow to the CPU cooler.

What Buyers Say
Many users are surprised by the JONSBO N3's ability to pack eight 3.5-inch hot-swap drives into such a compact Mini-ITX form factor, making it a favorite for DIY NAS builds. The case's build quality, with its thick aluminum and steel construction, frequently receives praise for feeling sturdy and rattle-free. However, the rubber grommet system for drive mounting is a recurring point of frustration, as drives are not smooth to pull out and the grommets can wear quickly. The front panel's magnetic attachment is a clever design choice, offering easy access to the drives.
“Okay, so it holds a ton of drives which is awesome for my media server, but seriously, those rubber things for the hard drives are a pain, they get chewed up and it's a struggle to pull them out!”
Common Praise
- Accommodates 8x 3.5-inch hot-swap drives, providing high storage capacity.
- Solid build quality with thick aluminum and steel, feeling sturdy and well-finished.
- Effective cooling for hard drives, keeping them below 40C even under load with included fans.
- Front panel with USB 3.0 and USB 3.2 Gen 2 Type-C ports offers modern connectivity.
- Ample clearance for CPU coolers up to 130mm and dual-width PCIe cards.
- Magnetically attached front panel allows for easy, tool-free access to drives.
Common Complaints
- Drive mounting system uses rubber grommets that make drives difficult to remove and can degrade.
- The PSU bracket requires an unusually long Philips head screwdriver for installation/removal.
- Included fans are 3-pin, limiting precise speed control and potentially contributing to noise.
- Cable management space is tight, particularly around the SFX power supply.
- Only one front button is available, forcing a choice between power or reset functionality.
- The included instructions are not detailed, making some aspects of the build unclear.
Ownership Tips
- The rubber grommets for the drives will likely show wear and tear after a few drive swaps.
- You'll want to invest in a long Philips head screwdriver specifically for the PSU bracket.
- Consider replacing the included 3-pin fans with 4-pin PWM fans for better noise control if you're sensitive to sound.
- Plan your cable routing carefully before installing components, as space is limited.
- The single front button means you'll have to decide if you want it for power or reset, as it can't do both simultaneously.
Frequently Asked Questions
Does the JONSBO N3 support SAS drives?
Yes, with a compatible HBA (Host Bus Adapter) card, the hot-swap backplane supports SAS drives.
What type of power supply does this case require?
It requires an SFX power supply, with a maximum length of 105mm. Standard ATX power supplies are not compatible.
Are the included fans sufficient for cooling hard drives?
Yes, the two built-in 100mm fans in the HDD compartment provide adequate cooling, keeping large capacity disks under 40C at load.
What is the maximum length for a graphics card in this case?
The case supports graphics cards up to a maximum length of 280mm.
Can additional fans be installed in the JONSBO N3?
Yes, there are mounting provisions for two additional 80mm or 90mm fans in the top compartment of the chassis.
Is the front panel easy to remove for drive access?
Yes, the diagonally slatted plastic front panel is magnetically attached and can be easily removed by pulling a fabric tab, providing quick access to the drive bays.
How many 2.5-inch drives can be installed?
In addition to the eight 3.5-inch hot-swap bays, the case has mounting provisions for two 2.5-inch drives.
Buying Guide
When looking at a NAS case, you're really buying a specialized box for your data. You need to think about how many hard drives you actually need, not just now, but in the future. Also, consider the size of the case and where it will sit, as some can be surprisingly large or loud. Cooling is super important for hard drives, so good airflow and fan options are key to keeping your data safe and drives lasting longer.
Drive Bays (8x 3.5" HDD + 2x 2.5" SSD)
This tells you exactly how much storage you can cram in there. 3.5-inch bays are for your big, spinning hard drives (think terabytes of movies or backups), while 2.5-inch bays are usually for faster SSDs for your operating system or frequently accessed files. More bays mean more storage potential.
Compatible Motherboard (Mini-ITX)
This dictates the size of the computer brain you can put inside. Mini-ITX boards are small, which helps keep the overall case compact. If you have a larger motherboard, it simply won't fit.
Power Support (SFX105mm)
This specifies the type and size of the power supply unit (PSU) you need. SFX PSUs are smaller than standard ATX ones, which is common in compact cases. You can't just use any old PSU; it needs to be SFX to fit.
CPU Cooler Support (130mm height)
This is the maximum height of the CPU cooler you can install. If your cooler is taller than 130mm, the side panel won't close. Good cooling is essential, especially for a server that might run 24/7.
Alternatives
If this case doesn't fit, look for cases supporting Micro-ATX motherboards for more PCIe slots, or those designed for ATX power supplies if you already own one. For quieter operation, prioritize cases with 4-pin PWM fan support or larger fan mounts.
