Jonsbo U4 B Mid Tower Computer Case
Redefine Beauty and Practicality

The Jonsbo U4 B Mid Tower Computer Case is perfect for DIY enthusiasts or computer geeks. It unites stylish design, great cooling capacity, and superior expandability. Take it home and build your own computer. It is available in two colors: Silver and Black.

Exquisite Look

With the U4, Jonsbo is once again presenting its talent for noble finished ATX cases and remains faithful to the timeless design of the U-series. The elegantly rounded corners and the classic appealing ensure that the U4 can blend in with any interior style.

Only a small “Jonsbo” logo decorates the plain and straight front, while the I/O-Panel is left unremarkable on the side panel and provides 2 x USB 3.0 as well as the obligatory HD audio connections. And the Power Button is illuminated blue during operation.

Roomy Interior

The Jonsbo U4 is a compact, yet solid aluminum ATX case without sacrificing high-end hardware compatibility. It offers no space for optical drives, and reduced space for 3.5” drives. Now, more space is available for installation of very powerful configurations. Users can install VGA cards up to 310 mm long and CPU coolers up to 170 mm high. The high-quality and excellently processed U4 case supports ITX, M-ATX and ATX motherboards. The installation of the motherboard is very simple - after you remove the left side panel it can be installed with little effort on the right side panel. An ATX power supply (max. 250 mm) can be installed in the U4. A total of seven PCI expansion slots are available.

The hard drive disks can be mounted using rubber suspension to guarantee silent operation of the system. Either two 2.5 " and three 3.5", or two 3.5 "and two 2.5" drives can be mounted.

Robust Cooling

For effective ventilation, the U4 comes with a quiet 120 mm fan preinstalled at the rear panel. The cooling system can be optimized by further fans, with mounting points for two 120 mm fans behind the front panel and a 120 mm fan at the bottom of the case.
