HozHoz - Im going to suggest making one thread about your build as opposed to one thread on a particular subject (we already covered the CPU). It keeps things nice, neat and tidy for you, and those helping you.
To answer quickly though - The H series is low end/budget. The boards are not as robust and there are few, if any, overclocking options. If you plan to overclock, you will want a Z based board. If overclocking is not in the cards, you can get away with an H series board.
