There's only the slot for the 120mm AIO, the Corsair H60 or H75 will fit nicely.  You could put a 240mm in there, but you'd either have to lay it flat under the GPU (and put slim fans on), or custom mod the chassis up top and remove the 120mm box.   360mm, no room. 
looking to upgrade the Aurora R11's AIO Liquid cooling system and I was wondering is there a slot for a 360mm one? or can I only use 120mm AIO's I also wanted to get one from corsair with RGB, any ideas or recommendations? I would like to note that I want to fit as big an AIO as possible for my CPU and if you happen to know a AIO system that would water-cool my Alienware 3080 and 10700k that would be amazing, thanks
Aurora R11, AIO upgrade
