there is this DAS light Rack Mount.http://www.musik-produktiv.de/daslight- ... -gold.html
It looks like you have to remove the Housing of the Original Interface and then mount it into the 19" Box.
The XLR get attached to the Front and the Buttons (which i like) i guess will get connected via a similar connector like on my FC Interface i own.
Also for the USB i would assume the connect a simple cable to the Back and there (i found no picture) use a a Neutric USB Plug, i would use hot glue to attach the USB to the Interface card and the Neutric Plug so it cant disconnect accidentally.
The only Item i could not figure out is about the DMX Leds, there is one on the Front of the 19" Housing but how do they connect it to the Interface ? Maybe the DASlight has some Pin connectors.
To be honest it would be fantastic if there would be a 19" Housing. maybe you can consider offering one.
If there would be Pin Connectors for the DMX Leds, and the 3 Buttons and the 7-Digit Leds would be connected via a removable socket it would be pretty easy to have this as an option.
