I only changed the RAM to a pair of Corsair Vengeance LP in order to add the air cooler because the normal corsair Vengeance could be blocked by the cooler.
Also, you dont need 32 GB of RAM, 16 GB is already overkill. The case has plenty of space, has windows, its a beast case and such things are necessary for your kind of build.
The PSU is one of the best, Tier 1, will handle your build flawlessly even with overclocks.
Good luck building that beast.
