If you strongly prefer mechanical keyboards over any other option, the Logitech G710 is probably the way you want to go. Essentially what you are getting here is a keyboard that already has dampening rings pre-installed at the factory. It will be louder than a basic keyboard, but not as loud as many competing mechanical models.
Beyond that feature, this one offers adjustable brightness settings on the backlighting, with the WASD keys available to be adjusted independently (so you can have them much brighter for instance while playing FPS games).
There's also a dedicated game mode button, meaning that you don't have to access any software or memorize a key combo to turn on game mode for anti-ghosting and disabling the Windows key.
