Inter-Tech S-3901 Impulse Review: Mid-Range Case with Eye-Catching Addressable RGB Illumination


The workmanship of the case appears flawless to us in the test. The paintwork looks extremely professional – no deviations or smudges can be seen at any point on the case. The case seems to be processed faultlessly. We do not notice sharp edges or poorly processed transitions in the test. We don’t like that much that the black of the right side wall doesn’t match with the black of the plastic strips and also the material thickness is relatively weak, but definitely still sufficient.

The side window is made of tempered glass and is therefore also well suited for everyday use. It is fastened with four rubberized screws so that there is no danger of accidentally falling out. The lighting elements of the housing are also fixed and have a high-quality effect. Here, too, the manufacturer seems to attach great importance to the use of flawless materials.

Overall, the quality of the workmanship is high. We can hardly find points of criticism here. Only the partly comparatively small thickness of the material and the colour deviation of the right side part can be mentioned negatively.


The equipment of the case seems quite appropriate for a midi tower in the mid price range. The product has not only two 3.5-inch drive bays and two 2.5-inch bays, but also two USB 3.0, two USB 2.0, one microphone and one headphone jack.

There are also mounting options for up to six 120 mm fans. Such a fan is already pre-installed. As an alternative to the five other 120 mm fans, four 140 mm models can also be fitted. Installation possibilities exist both in the front and in the cover. The standard fan is located at the back of the case.

The CPU cooler may be a maximum of 175 mm high, while the length of the graphics card may not exceed 275 mm according to official specifications. However, we were able to accommodate our ASUS ROG GeForce GTX 1080 Ti Strix with 298 millimeters despite the front radiator and fan. As already mentioned, the device also has a control board and an LED button for controlling the lighting effects. There is also the possibility of manual fan control via a device in the lid. Unfortunately, it is hardly possible to connect further products to the control board through the proprietary connections, since Inter-Tech itself does not currently offer any. Depending on how the housings with the control board arrive in the trade, however, this can still change. Only four additional 3-pin fans can be connected.

The housing also has openings for easy cable routing, a separate cage for the power supply unit, which is located in the bottom of the housing, and dust filters, which are located below the power supply unit. If required, a water cooling system in the size of 120 or 240 millimetres can be installed.

All in all, the case actually offers a very wide range of possibilities. It is therefore actually suitable for setting up extremely high-quality PC systems. In detail, this system construction will be considered in the next point.
