This article covers JONSBO V12 ブラック マイクロATX ミッドタワー PCケース.

Overview

The JONSBO V12 Black is a compact Micro-ATX mid tower PC case that stands out with its dual-curved tempered glass side panel and genuine walnut wood front trim. The 270° curved glass offers a panoramic view of your internal components, making it an excellent choice for builders who want to showcase their hardware. Measuring just 280mm wide, 301mm deep, and 275.5mm tall, this case occupies minimal desk space while still supporting standard ATX power supplies. The 8mm thick North American black walnut panel brings a natural, warm aesthetic that blends seamlessly into home or office environments. In terms of cooling, the V12 comes with two pre-installed 120mm fans at the front. Rear fan mounts (92mm and 80mm) are optional. This case is positioned as a mid-range option, targeting users who value unique design over maximum expandability.

Compatibility Guide

Motherboard support is limited to Micro-ATX and Mini-ITX—standard ATX boards will not fit. CPU cooler clearance is capped at 145mm, which rules out most tower air coolers; low-profile coolers or 240mm AIOs (mounted at the front) are recommended instead. Graphics card length is restricted to 260mm. This accommodates most mid-range cards like the RTX 4060 or RX 7600, but high-end triple-fan models exceeding 300mm will not fit. Power supply support is ATX form factor with a length range of 140–220mm. The front I/O includes one USB 3.2 Gen 2 Type-C, one USB 3.0, and a combined audio/mic port. Storage configuration options: either 2× 3.5-inch HDD + 1× 2.5-inch SSD, or 1× 3.5-inch HDD + 2× 2.5-inch SSD. All drives mount internally.

Product Info

Released in late 2025, the JONSBO V12 Black is a mid-tier case that prioritizes aesthetics. Its construction uses SGCC 1.0mm steel, 8mm solid walnut, and 4mm curved glass. At approximately ¥52,898 JPY (), it competes directly with other M-ATX cases in the same price bracket. Warranty is typically 1 year from the manufacturer.

Best Use Cases

Aesthetic-focused builds: If you want a PC that looks like a piece of furniture, the walnut and curved glass combination is almost unmatched in this price range. Perfect for living room or study setups. Compact M-ATX systems: For builders who need a small footprint but still want room for a moderate GPU and ATX PSU, the V12 offers a clean, space-saving solution. * Showpiece with RGB: The large curved glass panel provides an excellent view of RGB-lit components. Ideal for users who enjoy custom lighting and want to display their work. ## Alternatives
In the same price bracket, the Fractal Design Pop Mini Air offers better airflow with its mesh front and supports longer GPUs (up to 300mm). However, it lacks the natural wood aesthetic. The Cooler Master NR400 provides more CPU cooler clearance (166mm) and GPU length (325mm), making it a better choice for high-performance builds. The JONSBO V12 wins on design and uniqueness, but loses on pure expandability.

Things to Consider

The 260mm GPU length limit is the biggest constraint—it effectively blocks all high-end graphics cards and most dual-fan mid-range models from the latest generation. Always check your card's length before purchasing. CPU cooler height at 145mm is restrictive. If you plan to use an air cooler, only low-profile models (e.g., Noctua NH-L12S) will fit. For liquid cooling, a 240mm radiator can be mounted at the front, but that further reduces available GPU space. Finally, only front fans are included. For proper exhaust, you'll need to buy additional 92mm or 80mm fans. This adds to the total cost and should be factored into the budget. Overall, the JONSBO V12 is a niche product: beautiful but limited. Make sure your components fit before buying.
