Hi guys, I don't know if I'm posting this in the wrong place, but here it goes. I'm gonna buy a new cooler for my cpu, and I'd really like to buy the Corsair Hydro H80i, so I asked the vendor if this cooler is compatible with my case, a Thermaltake Versa I, and he said it wouldn't fit due to the radiator's size, if I install the cooler it wouldn't have enough space to install the motherboard. Is this information correct? If the Hydro H80i really wouldn't fit my case, the Hydro H75 would? The H75's radiator is smaller. Thanks in advance for your help, and sorry for the bad english if there's something wrong, it's not my first language. 
Here are the links for the case, the coolers and my motherboard, with the specifications, pictures and sizes:
