The Jonsbo D40 midi tower has a simple yet very stylish design. Thanks to the materials used, the exterior is understated yet eye-catching.

On closer inspection, however, it becomes apparent that the D40 is not just a normal midi tower. The typical arrangement of the components has been changed. This not only creates a different design, but also unusual cooling options.

By moving the power supply unit from its traditional position at the bottom of the case to the front, you have a completely new way to cool your components. The main supply of fresh air is no longer at the front, but at the bottom of the case. This ensures an unobstructed vertical airflow that utilises the laws of physics and additionally transports the heated exhaust air out of the case via a chimney effect.

There is space for three 120 mm or two 140 mm fans at the bottom to supply your system with fresh air. There is space for two 120 mm or two 140 mm fans at the top and one 120 mm fan at the rear.

If you opt for radiator operation, you can fit a 120 mm or 240 mm radiator at the bottom and top. An additional 120 mm radiator is possible at the rear. So you have plenty of options for cooling your components appropriately.

Graphics cards are coming with ever larger coolers and it is therefore important that you have enough space in your case. The D40 can accommodate graphics cards up to 355 mm in length. Hardware is becoming ever more power-hungry. The power supply units that can deliver this power require a correspondingly large amount of space. The D40 offers you space for power supply units up to 280 mm long. If your power supply unit is longer than 170 mm, there is still 305 mm of space for the graphics card.

If you prefer air cooling, you don't need to worry about this either. The D40 offers enough space for CPU air coolers with a maximum height of 168 mm. This means that most coolers will find their way into your case and reliably keep the temperatures in your system in check.
