Will these be compatible?

I have a CiT Vantage Case, GA-Z77-D3H Motherboard and have just ordered an ASUS GTX 660 ti Graphics Card. I want to know whether the GPU will fit. I have already built the PC and I'm pretty sure it will fit but I want to make sure. Any help would be greatly appreciated!!!
