Afternoon all. I bought a ex display Vortex STS 2070s from Currys at the end of April last year. Today I have found out that it should of come with an RGB controller. There was no RGB controller with the PC when I collected it. I will contact the Currys store that I bought it from but its doubtful that they will still have it. I have contacted PC Specialist support who say that they cannot help and have advised that generic RGB controllers are available to purchase everywhere. My question is this. Are they universal? If I buy a random RGB controller how do I know it will control the lights on my particular PC? Thanks in a anticipation.
