The JONSBO X400 Gray is a mid-tower ATX PC case tailored for gamers and e-sports enthusiasts building high-performance rigs with back-connect BTF motherboards. Its 3D skeletal framework and double-glazed tempered glass panels deliver a mecha-inspired aesthetic enhanced by ARGB lighting on the sea-view IO, making it ideal for showcase builds that prioritize both form and function.
Standout features include a patented mainboard auxiliary wind cooling system, where a rear 120mm fan channels air directly to the motherboard for better thermal management. With 13 fan positions, support for dual-sided 360mm AIO radiators, and 427mm GPU clearance, it handles demanding components effortlessly. Tool-free panels with anti-fall hover design make installation intuitive, while vertical GPU mounting (with optional bracket) highlights RGB effects.
Build quality shines through SPCC steel, ABS plastic, and tempered glass construction, paired with convenient front I/O: dual USB 3.2 Gen1 Type-A, one Gen2 Type-C, and audio jack. Dimensions of 18.11 x 12.2 x 18.76 inches keep it compact yet spacious for ATX/Micro-ATX boards, up to 176mm air coolers, and three drive bays (2x 3.5-inch HDD, 1x 2.5-inch SSD).
Potential drawbacks include the need for separate purchases for vertical GPU accessories and no included fans, which could add to initial costs. PSU support caps at 180mm, so check compatibility.
Overall, the JONSBO X400 excels as an e-sports ready case with unmatched cooling and build convenience, earning strong recommendation for enthusiasts chasing peak performance and style.
