Jonsbo U1 Mini-ITX Aluminium Cases

- Replaced by the Jonsbo U1 Plus Mini-ITX Aluminium Cases

The U1 should be the best choice for user who want to have a compact size but do not want to sacrifice performance. The U1 is compatible with most CPU coolers in the market and small size SFX PSU too

The Jonsbo U1 is the most compact model in the attractive U-series for home PC systems. The main feature of this case series is the timeless design line with the elegantly rounded corners and a very appealing exterior.


  1. Full aluminium chassis
  2. Extremely compact
  3. Compatible with Mini-ITX motherboards only
  4. Available with or without a side window
  5. Small form factor PSUs only

The refined unobtrusive design ensures that it can blend in with any environment. The blue illuminated power button is recessed into the sleek front; the I/O panel with 2x USB 3.0 and the HD audio connectors can be found on the right side of the case (as seen from the front). It is available with or without a side panel window.

The high-quality and well-manufactures ITX case supports Mini-ITX motherboards up to a maximum size of 170 x 170 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. The case is only compatible with Small form factor (SSF) power supplies, this help to maintain the tiny volume of the case.

The bottom of the case is where the hard drives are mounted. It is possible to install either a single 3.5" HDD or alternatively two 2.5" SSD/HDDs. All drives are mounted using anti-vibration mounts.

Due to the compact size the U1 offers no optical drive or expansion cards and thus follows the original ITX - idea. Mini-ITX motherboards are so feature rich that expansion cards are not always necessary. It is therefore aimed at users who are looking for a very stylish PC for typical living room or office applications. Thanks to the intelligent design of the case it is even possible to install CPU coolers with a maximum height of up to 135 mm, so even compact tower cooler can be installed.

The ventilation system of U1 is designed for lowest possible noise levels. Users can install up to two 80mm fans at the rear side of the case to ensure rapid removal of the heat from within the case. Air intakes in the front of the left side panel allow a continuously heat exchange. The use of aluminium contributes to the improved heat dissipation.

The stylish case rests on vibration-decoupled case feet in the appealing looks of high-quality Hifi components. While two USB 3.0 ports are available externally. Thus, external hard disk or USB drives can be connected quickly and easily.
