This article covers JONSBO N4 ブラック NAS PCケース.

Overview

The JONSBO N4 is a compact mini-tower case specifically designed for home NAS and small server builds. Its front panel features a solid 8mm-thick North American black walnut wood panel, giving it a natural, furniture-like appearance that blends easily into living rooms or home offices. Inside, the case can hold up to six 3.5-inch hard drives (four of which are hot-swappable) plus two 2.5-inch SSDs, making it an excellent choice for storage-focused users. Motherboard support is limited to Micro-ATX and Mini-ITX, and the power supply must be SFX (up to 125mm depth). With dimensions of 286mm (W) x 300mm (D) x 228mm (H), it occupies minimal desk or shelf space while still offering impressive drive capacity.
The case comes with one pre-installed 120mm exhaust fan, providing basic airflow. However, users planning to fill all drive bays should consider adding extra fans or optimizing cable routing to maintain adequate cooling. Overall, the N4 targets home server enthusiasts who prioritize storage density and aesthetics over GPU or CPU cooler clearance.

Compatibility Guide

This case supports only Mini-ITX and Micro-ATX motherboards — standard ATX boards will not fit. The power supply must be SFX or SFX-L with a maximum depth of 125mm. CPU cooler height is limited to 70mm, so only low-profile coolers or compact top-flow models are compatible. For graphics cards, the maximum length is 230mm, meaning most dual-slot mid-range cards will fit, but high-end triple-slot or long cards will not. When all six 3.5-inch drives are installed, interior space becomes tight, so always double-check GPU clearance before assembly. Storage connectivity is SATA-based: the four hot-swap bays use a backplane, while the remaining two 3.5-inch bays and the two 2.5-inch SSD mounts require direct SATA and power cable connections.

Product Info

The JONSBO N4 launched around 2024 and is positioned as a mid-range NAS-specific case, typically priced around ¥60,000 ($400 USD). The chassis is constructed from 0.7mm SGCC steel, with the front panel made from solid walnut wood for a premium feel. It supports one 120mm fan out of the box (exhaust), with an additional 120mm fan mount on the top panel. The case has four expansion slots, allowing for half-height expansion cards or a low-profile GPU. Warranty is generally one year from the manufacturer. Given its specialized design, the N4 competes directly with other compact NAS cases like the Fractal Design Node 304 or SilverStone DS380, but stands out with its wood-accented aesthetics.

Best Use Cases

  • Home NAS / File Server: The primary use case. With six 3.5-inch bays (four hot-swap) and two 2.5-inch SSD bays, you can build a high-capacity personal cloud or media server. The hot-swap feature makes drive replacement effortless without shutting down the system.
  • Compact Office Server: Ideal for small businesses needing a quiet, space-efficient server for file sharing, backups, or light virtualization. The wooden front helps it look professional on a desk or in a server room.
  • Media Center / Plex Server: Combine a low-power CPU, a small GPU (if needed), and multiple large HDDs to create a silent Plex or Emby server. The walnut wood finish complements home theater setups.
  • Who should NOT buy this: Gamers wanting to fit a RTX 4090 or a bulky air cooler; users with ATX components; anyone needing top-tier GPU performance or extensive CPU cooling. The restrictions on GPU length (230mm) and cooler height (70mm) make it unsuitable for high-performance gaming builds.

Things to Consider

First, the motherboard size restriction (only Micro-ATX and ITX) may force you to purchase a new board if you currently own ATX. Second, the CPU cooler height limit of 70mm means you cannot use standard tower coolers; you'll need a low-profile cooler like the Noctua NH-L9i or a compact AIO (though a radiator mount is not provided). Third, the PSU must be SFX/SFX-L, which is more expensive and less common than ATX units. Fourth, the included single 120mm fan may not be sufficient for a fully loaded NAS running multiple HDDs; adding a top exhaust fan is highly recommended. Finally, the GPU clearance of 230mm rules out most modern high-end graphics cards, so if you require strong GPU compute, look elsewhere. Over-specifying storage without adequate cooling could lead to higher drive temperatures, so plan your fan configuration carefully.

FAQ

Q: Can I install six 3.5-inch drives simultaneously?
A: Yes, all six drive bays can be occupied at once. However, doing so will severely limit airflow, so you should add an extra fan (top mount) and manage cables carefully to avoid overheating.
Q: Does the case support SFX-L power supplies?
A: Yes, SFX-L units up to 125mm depth are compatible. Just be aware that SFX-L cables are often stiffer, making routing inside the compact chassis more challenging.
Q: How many 2.5-inch SSDs can I install?
A: There are two dedicated 2.
