I'm considering (only considering!) an ASUS Maximus IV Extreme in a Raven 2 case. Everyone, including ASUS, is describing the Maximus IV Extreme as "extended ATX" but it seems to fall somewhere between ATX and eATX.
ATX is 305mm x 244mm, eATX is 305mm x 330mm. The Maximus IV Extreme is 305mm x 269mm and should fit in the Raven 2 - just - and probably quite a few others as well.
Am I overlooking something?
