A Coolermaster CK550 mechanical gaming keyboard Gateron Blue on your desk combines the wishes of a serious, minimalistic gamer. Coolermaster exchanges a flashy design for 'floating' keys on a sturdy, brushed metal top cover that compliments the lighting. The keyboard's lighting is configurable per key. You can control it with Fn keys and software. The keys have blue Gateron switches, which provide comfort during typing with a noticeable click for keystrokes.
