DK2108S - Orange BL, brown cherry SW Great keyboard! The mechanical switches really have a nice tactile feedback. I use this at work for programming, the orange back-light is pretty and non-invasive. (its also my fav color) It comes with instructions I couldn't readily find online, so if you're curious, there are 7 LED brightness levels you can set with [Fn] [0-7] or [Fn] Up/Dn. You can make them pulse by [Fn] 8. You can store the current setting in memory (so it keeps when your computer restarts) by pressing [Fn] s. ALL keys have lights, but out of the box the keys are all dark (you have to turn on illumination). The lock keys (caps, scroll, num) illuminate only when that lock is enabled. So normally for me, caps lock key is dark, and the num lock key is illuminated. I also love the calculator button. On all of my keyboards with added functions, that is the only key I ever used and found important. N-Key rollover is pretty neat and works (tested by keyboard mashing), but I don't see any practical need for more than 6. (3 realistically is enough for all of my hot keys) Keyboard feels substantial, definitely has some metal components inside, but I think the case is just hard plastic. Windows key just says 'Win', and I looked online, for cherry key switches you can get custom keycaps, which I will probably do.
