Jonsbo X400M has launched in China for ¥399, or around $59, with room for large PC parts despite its smaller frame. The Micro-ATX case borrows its exposed outer design from the X400 and offers five expansion slots.
At 460.2 × 310.3 × 416.3mm, the chassis takes up about 12% less space than its larger sibling, according to Jonsbo. Still, it is not exactly tiny, despite being made for smaller motherboards.
Build materials include steel, ABS plastic, and tempered glass. A dark gray metal finish gets a 2H hardness rating, while a GPU brace helps support heavy cards. There is also a rear cover to hide cables.
And cable management gets another perk. The X400M works with rear-connector motherboards, allowing compatible builds to keep more wires out of sight.
Component clearance is quite generous. Graphics cards can reach 427mm, while ATX power supplies get 180mm of room. Air coolers can stand up to 176mm tall, leaving space for many large CPU towers.
Cooling options are stacked as well. The case has ten fan mounts, with space for a 360mm or 280mm radiator on top. A separate 240mm liquid cooler can fit along the side.
But there is one detail buyers should check. Jonsbo has not confirmed that fans come in the box. Ten mounting spots do not mean ten fans are part of the deal.
Storage gets two bays for 3.5-inch drives and one for a 2.5-inch device. Up front, users get a 10Gbps USB-C socket and a pair of 5Gbps USB-A ports.
Fit may still get tricky with certain parts. A thick radiator, large fans, or tight cable bends can reduce usable room, even when the listed GPU and cooler limits look fine.
As for the price, that $59 figure is just a yuan conversion based on the stated exchange rate. Shops outside China may charge more once shipping, taxes, and local costs come into play.
For budget PC builders, the X400M brings broad part support and an unusual look at a low local price. Yet actual airflow and heat results remain untested, making independent reviews worth checking before a build.
