It is likely, but the same as other sockets there will be boards made in all sizes from E-ATX to ITX, maybe coming later on after the release of Haswell.
I think it is a safe assumption that ATX will be used, and likely M-ATX too.
Building a case? As in from scratch? If so i hope you are going to do a project log.![]()
Is it safe to assume the new Haswells will use ATX motherboards aswell?
I'm gonna start building a new case soon, and I would make it ready for my next big upgrade with Haswell.
