Don't worry guys, all of you make good points, and like always it is a matter of preference in the end, everyone of us has different priorities.
For N-ATX layout is perfect with ATX mbo, 3slot gpu and ATX psu, I really didn't have to compromise anything for ATX psu. With SFX you get a bit easier cable management, and you can use long 1-slot gpu in the upper position, but that is about it.
