Geeky, freaky or plain useless?
EVGA is known for several of its wacky accessories for overclockers using its motherboards. It's living up to its reputation with its latest one: an analog CPU clock-speed meter. By the looks of it, the device fits onto the case with its dial facing the user, latched onto the case using the side-panel screw. It connects to the system probably over the EVBot interface. Another possibility is that the device connects to the motherboard over USB (front-panel) headers. The meter's dial uses a GHz scale with starting unit at 1 GHz, going up to 6 GHz, with no distinct divisions between. So there it is, another means for you to show some momentary love to EVGA.
