Building in the D400 is a streamlined experience thanks to the generous 239mm width, which provides ample room behind the motherboard tray for cable routing. The thermal layout is particularly effective, allowing for a vertical airflow path from the bottom power supply shroud up through the top exhaust. With support for up to ten 120mm fans, users can create a high-pressure cooling environment that effectively manages the heat output of overclocked CPUs and high-TDP graphics cards. The inclusion of a dedicated Type-C port ensures the case remains relevant as peripheral standards evolve.
Compared to standard mid-tower cases, the Jonsbo D400 offers significantly more depth, allowing it to accommodate 450mm GPUs where many competitors cap out at 360mm or 400mm. While many cases in this category force a choice between side or top radiator placement, the D400’s internal geometry allows for simultaneous high-performance cooling configurations. Its 169mm CPU cooler clearance also exceeds the standard 160mm limit found in many slim towers, permitting the installation of flagship air coolers like the Noctua NH-D15.
What is the maximum graphics card length supported by the Jonsbo D400?
The case supports GPUs up to 450mm in length, making it compatible with virtually all modern flagship graphics cards.
Can I install a 360mm liquid cooler in this case?
Yes, the D400 supports 360mm radiators on both the top panel and the side mounting bracket for maximum cooling efficiency.
Does the front panel include a USB-C port?
Yes, the front I/O features one USB 3.2 Gen2 Type-C port for high-speed data transfer and modern device connectivity.
What is the maximum height for a CPU air cooler?
The chassis accommodates CPU air coolers with a maximum height of 169mm.
Q&A:
How many hard drives can be installed in the D400?
The flexible storage bays allow for various configurations, supporting up to three 2.5" SSDs or a combination of 3.5" HDDs and 2.5" SSDs across the rear cable area and power supply shroud.
