No Windows 7, you didn't mention if you need it or not (around $99). The HDD is OEM which means no cables, the MB should come with enough, if not it's like $5. Combination of NewEgg and MicroCenter, the NewEgg parts are all free shipping. Some prices are after MIR just so you are aware. SSD is included and you'll be able to overclock, cooling is included. You can find cheaper cases but $80 for the 400R is a nice price and a good case to work with.
