RGB Lighting
Stand out from the crowd with a keyboard that supports full RGB lighting. Many keyboards support RGB underglow, giving a really cool ambience to your desk. Some keyboards also support per-key RGB lighting, allowing each key to really shine. If you get into the code of the firmware (actually easier than it might at first appear), you can even customize the color of your keyboard according to whichever layer you are in at the time. Not only that, you could highlight specific keys, like your arrow keys or numpad, so they stand out from the rest of the keys in your layer. We've also heard that an RGB keyboard makes you a better gamer, so if that's your jam, this might be worth the investment!
