PC ATX, ITX, micro ATX Supported HDD sizes: 2.5,3.5" Number of 2.5" bays: 2 Number of 3.5" bays: 2 Side window Tempered glass panel(s) Aluminium, Steel Silver U5 is a product developed based on ATX motherboard specifications. The shell is made of 2.0MM aluminum magnesium alloy The main purpose of U5 development is to further optimize the length support of video card an power supply of Jonsbo middle-level aluminum case, to increase the height support for backplate wiring management, and to optimize the top spacing for better liquid cooler support. In the heat dissipation, 3 fans design on the bottom improve the air intake of the case and so optimize the overall heat dissipation performance. With numerous optimizations, there is no restriction for supporting high-end hardware anymore, users can easily build an unlimited high-performance computing platform with elegant metal texture.
