Overview

In Win 901 features a rather unique and classic design, in fact, the case is composed of a single aluminum block and two side panels made from tempered glass. The build quality is on very high level, aluminum and all finishes are very well made.
As mentioned, the base structure of this case is made out of 4 mm thick aluminum, the inner black shell is made of 1.4 mm aluminum, while the side panels are 5 mm tempered glass panels. The product is very solid and sturdy, but we do recommended to handle it with extreme care.
The front, top and bottom are pretty simple and clean with an elegant design while the rear part is a bit more elaborate. To allow the installation of the CPU cooler or a 92mm fan, the back outer panel is removable and allows an easy access to the workspace.
The storage department is located in the top right corner, placed into two sleds made of aluminum and feature hot-swap connectors. This solution is very interesting and will help you achieve great cable management. Inside the 901 there is also enough space for two 2.5" bays, one placed near the hard disk cage while the other is under the power supply. Overall, the 901 is able to accomodate two HDDs and two SSDs, which is more than enough for an ITX solution. As you can see from pictures, the case does not feature any 5.25" slots.
In order to maintain a clean design, In Win chosen to position buttons, USB 3.0 headers and audio jacks on the left side of the case, behind the 120 mm fan. Last but not least, In Win 901 sits on two solid supports with non-slip feet.
