The Jonsbo D200 is a Mini-ITX/Micro-ATX case with a curved tempered-glass showcase panel and a small digital temperature display. Its published limits are generous for a compact build—up to a 410 mm graphics card, 171 mm CPU air cooler, 170 mm ATX (PS2) power supply and a top-mounted 240 mm radiator—but those are manufacturer clearances, not a guarantee that every combination of parts will fit. Check the exact dimensions, cable exits, radiator thickness and mounting hardware for your planned build.

What size motherboard does the Jonsbo D200 support?
The D200 accepts Mini-ITX and Micro-ATX motherboards. It is therefore aimed at compact mainstream systems rather than full ATX boards. The five expansion slots provide room for a substantial graphics card or other add-in cards, but slot position, card thickness and power-cable clearance still need checking against the specific motherboard and GPU.

Jonsbo lists 410 mm as the maximum graphics-card length. Treat that as a stated limit under the manufacturer’s configuration, not as a universal promise. Measure the card’s complete length, including any front bracket or protruding cooler shroud, and check whether a front radiator, fans, drive hardware or power cables occupy the same space. A card that is nominally 410 mm or shorter can still conflict with those parts.

Cooling layout and radiator support
Top radiator
The user guide specifies support for a top radiator up to 240 mm, suitable for a 240 mm all-in-one liquid cooler. Confirm the radiator’s actual thickness, fan thickness and motherboard-RAM clearance; the published radiator size does not establish clearance for every AIO model.
Fan mounting positions
The listed positions are three 120 mm or two 140 mm fans at the top, one 120 mm fan at the rear and three 120 mm fans in the power-supply compartment. Jonsbo marks these fan positions as optional. The available material does not conclusively inventory which fans, if any, are included in the retail package, so verify the box contents with the seller or regional listing before budgeting.

What the specifications do not prove
No independent thermal, acoustic or airflow test was supplied. The mount count alone cannot establish operating temperatures, noise levels or the best fan direction for a particular build.
What does the D200’s temperature display show?
Jonsbo presents the display as a temperature-monitoring feature. The D200 guide identifies CPU-temperature monitoring and says the System Temperature Monitoring software must be downloaded and installed for normal operation. The cited material does not establish sensor accuracy, update frequency, supported operating systems or whether the software remains compatible with every current platform. Consider the display a convenience indicator rather than a validated measurement instrument.

Can the Jonsbo D200 fit a 240 mm AIO?
Yes, the manufacturer lists a top-mounted radiator up to 240 mm. Before purchase, compare the chosen AIO’s radiator and fan stack with the motherboard’s top-edge components and memory modules, then check tubing routing and screw-hole alignment. Also review whether the AIO changes the available graphics-card or power-cable space in your exact layout.
Storage and front connectivity
The guide lists up to two 2.5-inch drives and one 3.5-inch position, but mounting capacity is shared. Jonsbo specifies one rear 2.5-inch mount and one position in the power-supply compartment that can accept either a 3.5-inch hard drive or a 2.5-inch SSD. Plan around those shared locations rather than assuming two 2.5-inch drives plus a separate 3.5-inch drive can always be installed together.

External connectivity consists of two USB 3.0 Gen 1 Type-A ports, one USB 3.0 Gen 2 Type-C port and one headset audio jack. The specifications do not state charging wattage or display-output capability for the USB-C port.
Power-supply and build-clearance checks
The stated ATX (PS2) PSU limit is 170 mm in length. Measure the PSU body and account for the modular-connector area, cable bend radius and any drive hardware in the power compartment. Likewise, keep the 171 mm CPU-cooler limit as a starting point: backplates, side-panel curvature, fan clips and motherboard socket placement can affect the real installation.
- Record the exact GPU length and thickness, CPU-cooler height or AIO radiator/fan thickness, PSU length and drive dimensions.
- Compare each measurement with the D200’s published maxima and mounting locations.
- Check interactions: GPU versus front hardware, top radiator versus RAM and motherboard heatsinks, and PSU cables versus drives or bottom fans.
- Confirm connector orientation and cable-routing space, especially for a long GPU and modular PSU.
- Verify the retailer’s accessory list, software availability and regional return policy before ordering.
Availability and buying context
AKIBA PC Hotline! reported the D200 arriving in Japan in two colors in February 2026. That report does not establish current stock, price, warranty terms or availability in other countries. Jonsbo’s product page shows a System Temperature Monitoring setup entry dated 2025-05-27 and a D200 manual entry dated 2025-08-15; check the manufacturer or local seller for the latest downloads and regional support.
Who should choose the D200?
The D200 makes sense if you want a Micro-ATX or Mini-ITX build with a visible curved-glass presentation, a front CPU-temperature readout and room for long graphics cards or a 240 mm top radiator. It is a less certain choice if you need confirmed bundled fans, extensive drive capacity, validated acoustic performance or guaranteed software support across a particular operating system. In every case, select parts by their complete measured dimensions and by how they interact, not by one maximum number in isolation.
