Review on Airgoo Neon Addressable RGB PC LED Strip, 2x15.7inch Rainbow WS2812B RGBIC Magnetic ARGB Strip for 5V 3-pin Aura Sync, Gigabyte RGB Fusion, MSI Mystic Light Sync | Includes 12pcs Strong Magnetic Brackets by David Sharma

If you use this with ASrock MB over Polychrome, it works fine with Polychrome. The band is nice and flexible and can be attached almost anywhere you can use a magnet in the case. I like this strip over regular ribbon strips because the sheen is nice and even. With the band style they almost have to be hidden and this one I can place right on the front of the case. They can be connected in series or connected separately, allowing you to do almost anything. They also come with 3-pin adapters of both styles, so they can be plugged into most motherboards with a 5V argb connector. The included magnetic clips are handy and come in a variety of styles to attach at different angles. The stripes are very bright and saturated. You can match them to virtually any color. The only thing I would like is that they are in a 3 pack or maybe a pack. I need 3 and can't use the 4th. I'll probably order another one and just figure out where to put the fourth one. The only downside I would say is that they are a bit bulky and can take up some space.
