A white bracket that nearly universally fits GPU's in order to turn them into a hybrid liquid/air cooled card. Requires a compatible AIO cooler (basically anything from Corsair or NZXT will do). Drops temperatures wonderfully, got better overclocks and much less noise under load.
Unit was missing some hardware when I first bought it, so this will have extra brackets as NZXT shipped me a few spares. Also one of the washers is wonky because an Ebay buyer refunded the card after losing one of the screw/washer combos -_-
Used for roughly a year and a half, though the only moving component is the fan and it was inaudible over anything else in my system.
