Build Scope

The JONSBO D400 is a black ATX desktop case built from SPCC and SGCC steel with ABS plastic and integrated cured tempered glass. It accepts ATX, micro-ATX and mini-ITX motherboards, including back-connect designs, and allows vertical GPU mounting. Ten fan positions and support for 360 mm radiators on both the top and side panels give builders a wide thermal envelope for high-performance air or liquid cooling.

Fit Check

Verify that your graphics card does not exceed 450 mm in length and that your CPU cooler stays within 169 mm of height. The power supply must be no longer than 200 mm. Only a bottom dust filter is included, so plan intake filtration for the top, side and rear fan mounts if your environment demands it. Front I/O provides one USB 3.2 Gen 2 Type-C port, two USB 3.0 ports and separate audio and microphone jacks.

Upgrade Path

This chassis replaces cases limited to smaller radiators, shorter GPUs or standard motherboard layouts only. The jump is worthwhile when you need simultaneous top and side 360 mm AIO support, vertical GPU presentation or back-connect motherboard compatibility. Builders who require more than two 3.5-inch or three 2.5-inch internal drive bays, or who need front-panel dust filtration, should look elsewhere.

Questions about this item

What does the JONSBO D400 include and what must I buy separately?

The case ships with the chassis, integrated tempered glass panels, dust filter, and mounting hardware. Fans, radiators, power supply, motherboard, CPU cooler, graphics card and storage drives are not included.

Which motherboard form factor should I choose for the D400?

The D400 accepts ATX, M-ATX and MINI-ITX boards, including back-connect designs. Pick the largest form factor your build needs; all three fit the same mounting points.

What does the 450 mm maximum GPU length mean for my graphics card choice?

Any card up to 450 mm long will fit with the side panel closed. Measure your card including the power connector; if it exceeds 450 mm you must remove the panel or choose a shorter model.
