Some G-Series keyboards have grooves on the bottom. This is for cable routing and management so you can minimize loose cables on your desk. For example, the series of grooves at the front of the keyboard can be used with headsets that have longer cables. You can wrap the cable back and forth in the grooves to take up the cable slack, and then feed the cable out the front middle of the keyboard, eliminating excess slack and preventing the headset's cable from being caught in your hands while playing games.The product information is located on the bottom of your gaming keyboard.
