This is a Corsair Lighting Node Pro, a 6 port Corsair RGB hub and the 2 required cables to connect it all up (one to connect these 2 parts together and one to go in a USB2.0 Hub on your motherboard).
This is a fantastic piece of kit for anyone who wants to light up their PCs. The software is easy to learn and use. Would recommend to anyone looking for RGB.
This product is great, but if you live in a VAT exempt domain don't expect to get your tax deductible at source, they say they will do it via their office, but don't.
