I use an Astek cooler which makes the coolers for Corsair. Internally no problem
fitting that into that case. I'm guessing with the H100 instead to the H80 you will
be putting the radiator inside on the top of the case.
Edit. One thing to add to my statement, since the PSU is going on the bottom of the case, make sure you elevate the case
above the floor about an inch. Especially if it is on carpet. I have had to replace two of my friends PSUs( one Fortron, one Corsair) that burnt out because they overheated.
I'm a fan of Fortron PSUs and was impressed the thing last 2 1/2 years basically pushing hot air into a thick carpet!
Happy Cooling, the Prisoner.
