The new panel consists of 4mm thick tempered glass and will be sold via the firm's distributors for 39.00EUR. It's unknown if the company plans to ship new Dark Base 900 series cases with pre-installed tempered glass panels. At the moment, buying the extra panel seems to be the only way to get a Dark Base 900 with tempered glass.
The elegant and fully-windowed side panel fits all Dark Base 900 PC cases and gives you a perfect view of the top-end components inside your PC. The window is made of 4mm tinted and tempered glass, and is decoupled from the case with rubber elements to inhibit the transfer of vibrations.
