This article covers JONSBO N5 NAS PCケース.

Overview

JONSBO N5 is a purpose-built NAS PC case that accommodates up to twelve 3.5-inch hot-swap HDDs and four 2.5-inch SSDs, making it a strong contender for home server and small-office backup builds. It supports E-ATX motherboards and offers room for up to four GPUs, giving it unusual expansion flexibility for a storage-focused chassis. The front panel features a solid North American black walnut veneer, which brings a warm, furniture-grade look that stands out from typical rack-mount or industrial server cases. Internally, the drive layout is front-loading for the twelve HDDs with individual trays, while the four SSDs mount on the side panel. The PSU sits at the bottom and supports ATX units up to 240mm long, but if you populate all twelve HDD bays, the PSU length is limited to 170mm. Cooling is extensive: you can install up to eleven fans (120mm or 140mm) and radiators up to 280mm. The case comes with three pre-installed 120mm fans at the rear. Beyond storage, the N5 boasts eight PCIe slots, allowing multiple GPUs, capture cards, HBAs, or 10GbE NICs. This makes it suitable for homelab virtualization, Plex transcoding servers, or even lightweight AI/ML workstations that also need massive storage.

Compatibility Guide

Product Info

Released in late 2024, the JONSBO N5 sits in the mid-to-high-end segment of the NAS case market. Its current street price is around ¥71,608 (approx. $480 USD) on Japan. The case is built from steel, aluminum, and a real walnut wood veneer, weighing about 7.5kg. It offers a 1-year manufacturer warranty. The combination of 12 hot-swap HDD bays, E-ATX support, and four-GPU capability is rare at this price point, making it a compelling option for serious home server builders.

Best Use Cases

Home NAS Builders: Users who need 12+ HDDs for bulk storage. Hot-swap trays allow drive replacement without downtime. Works great with TrueNAS, Unraid, or Synology DSM (via hardware). Homelab Enthusiasts: Those running virtualization clusters with multiple GPUs, HBAs, and 10GbE NICs. The 8-slot PCIe backplane and E-ATX support provide room for growth. Media Server Owners: Plex or Jellyfin users who need both massive media storage and a GPU for hardware transcoding. The N5 handles both roles without compromise. Not suitable for: Gamers who want a compact glass side-panel case, users who prefer quiet operation out of the box, or anyone looking for a budget mini-tower. ## Alternatives
Fractal Design Define 7 XL: Offers 18 HDD bays (with optional brackets) and superior noise damping, but lacks hot-swap trays and costs more. The N5 is better for server-style hot-swap workflows. SilverStone CS381: A Mini-ITX case with 8 hot-swap bays and a more compact footprint. While great for small builds, the N5 offers more drive bays and full ATX/E-ATX support for those who need expansion.

Things to Consider

The PSU length restriction when using all 12 HDDs is critical. You must choose a short ATX PSU (≤170mm) or reduce drive count. SFX power supplies are not supported. CPU cooler height is limited to 160mm, so high-end air coolers are out. Plan for a 240mm or 280mm AIO. The case is 355mm wide, taking up significant desk or floor space. It's not a rack-mount chassis, so measure your space carefully. Only three 120mm fans are included (rear). To achieve full airflow, you'll need to purchase additional fans. The walnut veneer adds elegance but is susceptible to scratches and moisture; handle with care and avoid placing drinks nearby. ## FAQ Q: Are the 3.5" drive bays hot-swappable? A: Yes, all twelve front bays use hot-swap trays with SATA backplanes, allowing drive replacement while the system is running. Q: How many graphics cards can I install? A: Up to four full-size GPUs, but you may need to reduce HDD count if using very long cards. Q: Is this case quiet? A: Not out of the box. The included fans are not particularly quiet. For a silent setup, consider replacing them with Noctua or be quiet! fans.
