Jonsbo C6 (Black)

This article covers Jonsbo C6 (Black).

Overview

The Jonsbo C6 is a compact mini-tower PC case from JONSBO, a brand well-known for its minimalist and space-saving designs. Measuring just 202 x 266 x 295.2 mm (W x D x H) and weighing a mere 2.3 kg, this case is built around 0.7mm steel construction, giving it a sturdy yet lightweight feel. It supports both ITX and M-ATX motherboards, making it a flexible option for desktop builders who want to save space without sacrificing core compatibility.
The front I/O panel includes a USB Type-C port (20-pin header), one USB 3.0 port, and a combined audio/mic jack. Power supply support is ATX PS/2 up to 185mm in length, mounted at the bottom. Storage options are decent for a case this size: two 2.5-inch SSDs and one 3.5-inch HDD can be installed. That makes the C6 a practical choice for a home server, an office PC, or a budget gaming rig.
Positioned squarely in the entry-to-mid tier, the Jonsbo C6 is aimed at users who prioritize a small footprint and affordable pricing. It suits casual builders who don't need extensive water-cooling options or massive GPU clearance, and it excels in scenarios where desk space is at a premium.

Compatibility Guide

Motherboard compatibility: ITX and M-ATX. However, because the interior is tight, you should pay close attention to the width and height of the M-ATX board. The power supply is mounted at the bottom, so ensure the unit's length doesn't conflict with the motherboard connectors.
CPU cooler clearance is 75mm maximum. This is quite restrictive: typical tower coolers are far too tall. You'll need a low-profile air cooler (under 70mm) to fit inside the case. Liquid cooling (AIO) is generally not supported, as there is no radiator mounting space.
The power supply can be a standard ATX unit up to 185mm long. Cable management is tight, so it's best to choose a modular PSU that is 160mm or shorter. Front I/O uses a 20-pin Type-C header and a USB 3.0 header on the motherboard, so your board must have these connectors. For the storage, 2.5-inch drives use side brackets, while a 3.5-inch HDD mounts at the front with a dedicated bracket.

Product Info

The Jonsbo C6 was released around 2023 and is available through online retailers globally. Pricing sits roughly between 8,000 and 10,000 yen (or about 60-80 USD), placing it at the affordable end of the spectrum. Warranty is typically one year, depending on the seller. It's made of 0.7mm steel and comes in black (also white is available).
The main specs are: external dimensions 202 x 266 x 295.2mm, weight 2.3kg, two 2.5-inch drive bays, one 3.5-inch bay, front USB 3.0 and Type-C, and support for ATX power supplies up to 185mm. The interior is designed for bottom-mounted PSUs.
Overall, this is an entry-level mini tower that focuses on space efficiency. It competes with other small-form-factor cases (e.g., Mini-ITX models from Fractal Design or Cooler Master) but offers a lower price and wider M-ATX support. It's an excellent choice for building a compact system on a budget.

Best Use Cases

• Compact desk setup: If you want a desktop PC that doesn't dominate your desk, the C6's tiny footprint is perfect. It can be placed on a bookshelf or under a monitor, and the lightweight build makes it easy to reposition. Great for home offices or study areas.
• Budget gaming PC: With a modest CPU and a shorter graphics card (typically under 260mm), the C6 can house a low-profile cooler and an ATX power supply. It's not designed for high-end GPUs, but for 1080p gaming with something like an RTX 4060 or RX 7600, it fits nicely if you check dimensions. The front I/O offers Type-C, which is nice for modern peripherals.
• Home server or NAS: The ability to install a 3.5-inch HDD and two SSDs makes it a good candidate for a small home server. With a low-power CPU and a compact PSU, you can run 24/7 without taking much space. However, drive cooling is passive, so ensure adequate ventilation.
• Who should avoid: If you plan to install a large tower cooler, a 360mm radiator, or a 27-30cm+ GPU, this case is not for you. The internal volume is simply too small. Also, if you prefer extensive cable management or interior customization, you'll be frustrated by the tight fit.

Things to Consider

The primary limitation is CPU cooler height: only 75mm. This rules out most aftermarket coolers and pushes you toward low-profile variants like the Noctua NH-L9i or a 120mm AIO (which still doesn't fit because no radiator space is provided). In practice, you'll be limited to stock coolers or slim coolers that may have noise or performance compromises.
Graphics card clearance is not officially specified, but from user testimony and measurements, cards longer than 260mm are risky. Many dual-fan models are around 250-270mm; measure before buying. Similarly, the power supply area is cramped, and using a non-modular PSU will make cable routing difficult.
