If you choose ATX board then choose ATX case.
It gives you an idea on how to save yourself some money to.
I used CD/DVD rom drives from other computers but they were pritty new any way.Try get a board with 4 SATA ports this way you can add more SATA HDDs or even SATA optical drives.
Pick a few ideas from the links and we can give you a bit more advice on the items.No need to go over board on prices.
Maybe a board with 4
