The Challenger sports a normal QWERTY layout, complete with directional arrows and num pad. The function keys run along the top of the board, though the print screen and scroll lock functions have been moved up from the 'home' key bank. Media function keys (pause, play, skip), volume, brightness, and profile switching complete an uninterrupted line of keys along the top.
Key lock indicators as well as a profile display are at the north of the board, centered between two unique plugs for positioning the fan. Five programmable keys are on either side of the keyboard, labeled T1 through T10. The bottom of the Challenger declines to meet the surface, creating an ergonomic wrist-rest and giving the board a ellipses-like appearance.
On the top side of the Challenger Pro, you will find the plug for the modular USB cable, as well as a built in 2-USB hub. There are a few coves hidden from view as well, one to store the 30mm fan, and a 'U' channel that runs underneath the board to help manage the slack of the USB cord.
