Hello, I have just spent all week trying to decide which x79 mobo to get and decided to get a Gigabyte X79-UD5...... The problem is i just noticed its e-atx, the mobo is 305x264mm, my old x58 mobo was 305x244mm, its only 20millimeters larger than my old x58..... It should fit in a antec 1200?? Will most of the stand-offs line up?? I'm starting to think i should of kept me old x58 now... Many thanks.
