Cooler Master Storm Inferno mouse @ Guru3D
Quote: "A mouse obviously targeted at gamers, but Cooler Master diversified and refined it even a little more as it is a mouse targeted at MMO's. This gaming peripheral features a total of 11 buttons, nine of which are actually programmable, 128kb onboard memory, a Rapid Fire Tactical key and a Storm Tactics Multiplier key that gives access to 32 extra programmable outputs for macros, scripts and other unique commands. All that armed with a 4000 DPI twin laser sensor."
