Setting up a New mobo

If i set up a new mobo, going from a mobo with ati express integreated to a mobo with n4 sli technology, can i just changed the hard drives with no problem or will i have to reformat it.

What does the mobo support? SATA, IDE, E-IDE, or?

actualy i changed my mind on the mobo, but i ll show you waht i ahve right now. thanks again for your help.

I'm going from this:

and i have catalyst and all that stuff installed, but i want to know if i can jsut switch harddrives no problem or if i have to reinstall everything, which i believe is like formatting itand started brand new.
