Jonsbo U3 Micro-ATX Aluminium Cases

The U3 is the largest of the models in the attractive U series aluminium cases. Larger than the U1 and the U2, the U3 can accommodate ATX PSUs, Micro ATX motherboards and a graphics card with ease.

The U3 is the largest of the attractive U series cases from Jonsbo. The main feature of this case series is the timeless design line with the elegantly rounded corners and a very appealing exterior.

The refined and at the same time unobtrusive design of the case ensures that it can blend in with any interior style. The blue illuminated power button is recessed into the sleek front, as well as the I/O panel with 2x USB 3.0 and the HD audio connectors. The U3 is made of 2.0 mm thick anodised aluminium and available in black and silver.

Based on experience and after careful study of current customer requirements, Jonsbo’s focus was to develop a case series to implement the original M-ATX/Mini-ITX - thought. For this reason, they decided not to implement assembly areas for optical drives and long video cards. VGA cards up to a length of 260 mm length and CPU coolers up to a height of 175 mm are supported – which allows for the installation of very powerful configurations with sufficient space for most popular configurations.

This high-quality and well-manufactured Micro-ATX case supports motherboards up to a maximum size of 245 x 245 mm. The installation of the motherboard is very simple - after removing the left side panel it can be installed with little effort on the right side panel. ATX power supplies can be installed in the U3 and a total of four PCI expansion slots are available.

In order to guarantee a particularly smooth-running system, the hard disk drives are anti-vibration mounted at the bottom of the case. Either install two 2.5” or one x 3.5” HDD / SSD. In additional a 3.5” HDD can be accommodated in side-mounted HDD rack.

For effective ventilation the U3 comes with a quiet 120 mm fan preinstalled at the rear panel. The speed of the fan can be adjusted via an external, multi-stage switch individually to the users liking.

The U3 is aimed at users who are looking for a very stylish PC for typical living room applications. With space for up to four expansion cards and a high-performance graphics cards means a very compact and powerful PC can be configured.

The stylish case rests on vibration-decoupled case feet giving it an appealing look of a high-quality Hifi component.
