TechPowerUp posted a review on the CORSAIR K68 RGB Keyboard + PBT Keycaps
A quote from the article:
CORSAIR has taken last year's K68 and given it the magic of RGB backlighting. Featuring per-key 16.8M colors that can be controlled via their excellent CUE driver, or even onboard controls now, and keeping the IP32 dust and spill resistance, it is a budget friendly mechanical keyboard for those wanting Cherry MX RGB switches as well.CORSAIR K68 RGB Keyboard + PBT Keycaps Review @ TechPowerUp
