"The iCUE 4000X RGB is a successor in many ways to the iCUE 465X RGB, and Corsair has taken steps to remedy issues the latter case suffered from. My personal favorite for improvements is how they created enough room to mount radiators to the front, top, and rear fan spaces! Users no longer have to front mount their radiators, or try to jam it into the top fan area while blocking their RAM."
