Inside the Sharkoon DarkGlider
Under each of the five feet there is a screw you need to remove. Once they are out of the way the mouse will almost fall apart in the two halves, there aren't any funny clips or anything to hold you up. You can see there is quite a bit of wiring talking between the two so don't go yanking at the mouse.
With the weighting system used here, the Avago ADNS-9500 is fit almost under it as the PCB ends. Just above and right of the sensor is the 16-bit MCU controlling all the functions and talking to the PC.
Omron switches are used under the left and right click buttons, while the rest of the buttons use the round pad style switches, like you see for the tilt wheel function.
As for the top half of the mouse, there are three sections to mention. Furthest left is the connection to the back of the LCD screen with the page forward and page back buttons on the PCB behind the ribbon cable. The PCB in the middle is what contains the DPI buttons and the favorite's button on the top side.
Stitching up the patient and seeing it come to life afterwards is always a great feeling. In this image of the DarkGlider you can see the DPI LCD display is now illuminated and it will always be red, this you cannot change. If you look close enough, it is displaying 800 DPI, which is the default and lowest setting.
Stepping back a bit you can barely see the glow of the LCD screen, but now you can see the logo is illuminated. This color can be changed to one of 31 other preset offerings.
