This article covers JONSBO Z20 ブラック Micro-ATX ミニタワー PCケース.

Overview

The JONSBO Z20 Black is a Micro-ATX mini tower PC case that packs high-performance hardware into a compact 20-liter volume. It supports graphics cards up to 363mm long and CPU coolers up to 164mm tall, while featuring a detachable carry handle on the top panel for easy transport to LAN parties or events. Both the front and top panels are constructed from 2mm-thick steel with a single-piece bending process, giving the case a rigid, premium feel. A large area of square mesh openings combined with full-coverage magnetic dust filters ensures excellent airflow and dust protection. Internally, the case accommodates ATX, SFX, or SFX-L power supplies in a bottom-mount configuration, and offers storage for up to two 2.5-inch SSDs plus one 3.5-inch HDD, or three 2.5-inch SSDs. The front I/O panel includes USB 3.2 Gen 1 Type-A, USB 3.2 Gen 2 Type-C, and separate audio/mic jacks.

Compatibility Guide

The Z20 supports Micro-ATX and Mini-ITX motherboards. Power supply options include ATX, SFX, and SFX-L, with an additional side-mount option for SFX units. CPU cooler clearance is 164mm for Intel CPUs and 163mm for AMD CPUs. The top panel can house a 240mm AIO liquid cooler with up to 60mm radiator thickness. Graphics card length support reaches 363mm, but actual clearance may vary depending on PSU placement and cable routing. It's recommended to check the official compatibility images before building.

Product Info

Released around 2024, the JONSBO Z20 Black is priced at approximately ¥35,700 on Japan. The case is constructed from steel and tempered glass (side panel), and supports both air and liquid cooling. Positioned as a mid-range compact case, it targets users who want high expandability and portability in a Micro-ATX form factor. The detachable handle sets it apart from most competitors in this size class.

Best Use Cases

First, it's ideal for gamers who attend LAN parties or events. The top carry handle allows one-handed transport, making frequent moves effortless. Second, it suits DIY builders who want a small footprint without sacrificing high-end components. Despite its compact size, the Z20 fits long GPUs, large air coolers, and 240mm AIOs. Third, it works well for creative professionals or home users who place their PC on a desk. The understated black finish and tempered glass side panel blend into any workspace.

Things to Consider

The Z20 only supports Micro-ATX and Mini-ITX motherboards — standard ATX boards will not fit. When installing a 240mm radiator on the top, check for clearance with RAM and motherboard VRM heatsinks. Cable management space is limited due to the bottom-mount PSU layout, so a fully modular ATX or SFX power supply is recommended for easier assembly. Direct competitors include the Fractal Design Define 7 Mini and Cooler Master NR200. The Define 7 Mini offers better noise dampening, while the NR200 is more compact. However, the Z20's carry handle and class-leading GPU clearance give it a unique edge for portable builds. ## Alternatives
Fractal Design Define 7 Mini is quieter and costs around ¥12,000, but its GPU clearance is limited to 331mm and it lacks a handle. Cooler Master NR200 is even smaller at 18L, but restricts GPU length to 330mm and CPU cooler height to 155mm, making it less flexible for high-end parts. At ¥35,700, the Z20 is pricier than both, but the combination of a carry handle, generous GPU clearance, and solid build quality justifies the premium for users who prioritize portability and expandability.
