For my model, I went middle of the road; the speakers with RGB. Razer is awesome about the lighting integration, like some market leading stuff. Their Chroma Studio is intuitive and all their products are easily tied in together for perfect sync; the Nommo speakers are no different. The down-lighting is the perfect touch for these to just float on top of your desk, and while they come in a very bizarre cylinder shape (I'll admit it I wasn't expecting a massive pair of cylinders when I bought them) they're a good size that should be able to fit right in with any setup. Unless you work on a cardboard box; we feel for you.
Now for the sound. I do video/audio editing as that is my job; in my spare time I do casual gaming. Both of these tasks are demanding from a sound perspective, and let me tell you dear reader that these bad larry's, they don't disappoint. In FPS games, the immersion is just as good as a headset (distance of 2-3 feet), and in AAA games, the atmosphere they create is just breathtaking. Like if you've ever played Alien: Isolation, these speakers will make you wish you hadn't.
When I'm editing interview shots for my clients, the depth to their voices is so rich and clear but so crisp and I just realized I sound like a commercial for a Hershey's chocolate bar but it's true. I cannot stress how beautiful the audio quality is on these, it's simply staggering. I recommend waiting for a sale on the Chroma model, trust me.
You need these speakers.
