yea normally try to get a mobo and case that max out almost together... i have 6 SATA II ports and 6 3.5" bays (1 external, currently 2 in use) and one pata connection with my dvd burner off it (case has 4 5.25" bays)... want to get that running on sata tho, but so basically if I maxed out my mobo it would equally fill up the case, that was my logic.
