Input devices are arguably the most important pieces of hardware you buy for your PC. A $5,000 computer is only as good as its peripherals, and by the same token, a good keyboard and mouse can make a budget rig feel like a million bucks. I have recently become a collector and connoisseur of the finer input devices such as mechanical keyboards. When asked to review a new mouse from Cooler Master, I jumped at the chance to put this device through the paces.
