After having many, many complication with my old build which was originally bought around this time in 2012 I have finally switched many parts out to do my "rebuild."Here are the parts that are carrying over from my old Rampage 4 Extreme based system...

All I need to know is will it fit because I am concerned about it being larger than a standard ATX mobo even though the Corsair Obsidian 650D has an 8th PCI slot and plenty of room in the other dimension. Any help is greatly appreciated.
