Matbe spotted the upcoming ROG G-Panel from ASUS at CES 2009. This device has a color LCD display and occupies two 5.25" drive bays, although it can also be used on your desk. The G-Panel enables you to overclock, adjust fan speeds and monitor your PC in real-time, just as if you're in the BIOS.
The G-Panel will be compatible with some of the Republic of Gamers motherboards from ASUS but a compatibility list isn't available yet. Pricing and availability is unknown as well.
