So, there is a set of RGB lights that are AMAZING. They are made by NZXT and are called the HUE+. It's $60 for the kit, but you can have literally and color you want if you ever wanted to change the theme. You'll have to install this CAM app to use it, and it's also very useful, I use it myself. There is also another cheaper solution by the manufacturer Bitfenix.
