Corsair has just started selling the White variant of their XC7 RGB CPU water block. The XC7 RGB originally launched as just a standard black variant, but with the popularity of white components and build they have launched the white variant (model: CX-9010005-WW). This variant is currently available from Corsair’s website for $74.99.
The block has a nickel-plated copper finish with a clear acrylic top and a outer pearl-white accent. The top has addressable RGB LEDs with a standard 3-pin input, which are of course compatible with Corsair’s iCUE software. The block has standard G1/4″ fittings and supports all modern mainstream sockets. If you are doing an all-white build this is definitely a block you might want to look into.
