QT03A Black E-ATX Chassis with Side Glass Panels

Jonsbo QT03A Black E-ATX Chassis with Side Glass Panels

The QT03A is a classy midi tower from Jonsbo that features a simple front panel made of brushed aluminium and with high-quality 5mm tempered glass side panels.

The QT03A features a simple yet elegant solid brushed aluminium front panel and two 5mm tempered glass side panels. The I/O-Panel can be found on the front of the top panel and offers a 3-stage fan control, 2x USB2.0 and 2x USB3.0 ports as well as HD audio connections. A unique feature of the QT03A is that the I/O-Panel is separated from the front panel, meaning that the front can be removed for cleaning with very little effort.


  1. Elegant tempered glass side panels
  2. Sound-absorbing front and top panels
  3. 3-stage fan controller (controls up to five fans)
  4. Supplied with three 120mm quiet case fans
  5. Water-cooling supported
  6. Innovative cable management

The QT03A has been designed to emit as little noise as possible. The front and the top panel of the case are lined with sound-absorbing materials. In combination with the sound-insulated front panel, the hard drives and power supply are decoupled from the main chassis. the case also has noise reduction anti-vibration case feet, as well as the pre-installed fan control. All of these feature mean almost no noise reaches the outside of the case.

The ventilation system of our QT03A is designed to deliver the best possible cooling performance with the least amount of noise. Up to four 120 or 140 mm fans can be installed. Three 120 mm fans are supplied (one at the rear and two at the front). The fans have been designed to provide ample airflow to the interior of the case whilst remaining as quiet as possible. To help control the noise and speed of the fans a 3-stage fan control is supplied that allows you can choose between three different settings. HIGH, as you would expect runs the fans at full speed to provide the maximum cooling. LOW, reduces the fan speeds and noise levels whilst still providing adequate airflow. The final setting is OFF, which turns off all connected fans.

The QT03A has also been developed to allow the installation of water-cooling radiators. Behind the front panel allows for 120, 240, or 360 mm radiators to be installed. Please be aware that there is approximately 65 mm space between the front and the power supply cover available. Please consider this when selecting your water-cooling radiator.

A further special feature of the QT03A is the two-piece of the chassis. The power supply and hard drives are separated from the motherboard area. Thus a thermal separation of the two regions is ensured. The dust filter under the power supply can easily be removed and cleaned. Another dust filter can be fund behind the front panel.

The hard drive cage of the QT03A accommodates up to two 3.5" drives. The hard drives is decoupled and installed without any tools. At the back of the motherboard rack, there are three brackets for installing 2.5" drives.

The QT03A offers innovative cable management with a specially designed mounting plate, which not only facilitates cable routing, but it can also be used to support long VGA cards. Seven PCI slots for expansion card installation are available on the rear panel.
