First time building a computer and I'm not sure the parts will fit inside the case

Solution
The only parts that will be questionable, will be the card due to its length. The card is ~12" long. The case's web page shows that there is 28cm (~11") of room for cards. But they show that measurement to the lower drive cage. The upper drive cage sets back further and looks to be enough room if the card sits in the first expansion slot. Unfortunately, the board you chose has the first 2 slots as x1. The x16 slot is the 3rd position down. So it will be iffy with that board. You might want to look for a board that has the PCIe x16 slot as the 1st slot down.
