Yep, it will fit. That's an ATX mothboard and an ATX case. They are made for each other
All jokes aside, you shouldn't have any problem with putting the MB into the case, but I do have some concerns. P67 is kind of an old chip. If you plan on doing any overclocking I'd recommend a Z77 board. If not, I'd recommend a H77 or B75 chipset. The newer boards have all your bells and whistles, as well as compatibility with the newer Ivy Bridge processors. Also, the motherboard you chose does not have an internal USB 3.0 header, so you won't be able to use the USB ports at the front of the case.
And, I'd recommend you not put you motherboard in until you get all of your parts. You could damage it.
