"The 'Prism' in the product name probably refers to the LED backlight around the I/O control panel, Riotoro logo at the bottom of the front panel, and the two 120mm LED front fans which can be set to one color (red, green, blue, cool white, yellow, pink) or automatically sequence through a 256 color "rainbow" palette. The two LED fans lighting the case interior should make the black case glow with a myriad of colors, pleasing many computer enthusiasts."
