Its an LGA775 board,Gateway has proprietary mounting points on the board and case. Trust me if I could go different I would,with the mounting points being more rectangle than square I dont have a choice but to use gateways OE solution. I wanted to use something similar to this http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=4244280&CatId=1588 but the way the hold downs are posistioned I cannot securely fasten it to the mobo.
