Jonsbo team has been trying to provide users with a solid material and moderately priced ATX aluminum case, limited by the high cost of aluminum, we have not been able to achieve this wish.
The rapid popularization and lowering of the SSD price gives us the opportunity for the development of U4, by reducing the amount of HDD 3.5 support and canceling the optical drive rack, under the condition that the high-end hardware compatibilities do not affected, the Jonsbo team has created a mid-level aluminum ATX case for users.
U4 can support 170mm height CPU radiator, 310mm length high-end display card, and 120 / 240mm cooler. In materials, U4 keeps the same level as the high-end shell, 2mm thick aluminum plate is used for the shell, 1.0mm SGCC steel plate is used for the structure, and the tempered glass Full 5mm thickness is used for the transparent side plate, the good materials used and the reasonable structure design make U4 slightly small case but with solid structure and reasonable expandability with full aluminum light effect.
U4 was launched in late 2016, the outer shell is made of 2.0mm aluminum-magnesium alloy, with the accumulated experience of Jonsbo team in drawing anode surface processing of many years, the design style it continues the feeling of simplicity, simple aerodynamics and strong metallic.
By using exterior aluminum and interior steel with innovative structural bonding technology, it perfectly fuses the strong structure and good appearance of the product.
U4 makes use of full tempered glass for side plate and CNC machine to cut the edge precisely, so that the space between them can be precisely controlled and the edges are smooth, which will not hurt our hands.
The fully tempered glass side plate not only provides a wide angle display for illuminated hardware, but also provides a better solution to isolate noise and reduce resonance than traditional metal side plate housing.
