I was wondering if this is possible? I am modding a power mac g5 case into a Pc and i have the motherboard tray i need but i want to put in a closed-loop water cooling cpu cooler as a fan cpu cooler would be too tall to fit in the case i think, and i only have 1 dedicated fan mount on the motherboard tray. it is an 80mm mount for a fan, i was wondering if you could swap out a 120mm radiator for example from a corsair h80i and put in a 80mm radiator.
