Great keyboard, just as quiet as I wanted
Really great, easy to configure backlighting, soft keys (apart from the space bar, which is very audible), hyper-responsive, the keyboard is rather heavy but for a desktop it's perfect.
I was a bit worried about the different coloured keys, but the classic versions were in the box, so they were easy to change.
The fact that you can unplug the cable from the keyboard is also handy for transporting it or changing cables without having to do any soldering (which hasn't happened with this one yet ^^).
