Unmatched Quality

This fine aluminium structure makes the perfect contrast to the tinted glass on the front and top panels. Indulge yourself in this exquisite combination to showcase a simple, yet elegant system aesthetic.

Quick-Release Side Panel Button

The tinted tempered glass side panel is the window to the soul of your system. Use this convenient and screwless quick-release design to remove the side panel by simply pressing a button!

Details that Matter

Small details matter to us! The high-quality aluminium panels and power button are presented with a delicate classic hairline finish and all the edges are beautifully polished with a diamond cut to prevent scratches. To top it off, the tempered glass side panel is embellished with an InWin logo engraved on an exquisite metal badge.
