Hi Haroon,
You'll only need a SATA cable and SATA power.
RAID is a type of joining disks to increase speed, size or both - but is 100% NOT advised between SSD and a normal HDD as SSD speeds are already lightning fast.
This setup will give you a C Drive and a D Drive (Presuming windows) and then whatever your DVD Drive is set to (Normally E Drive in this setup)
If you plan to reinstall windows there are a few extra steps you need to do but NONE of them require more hardware than the bracket, power and SATA data cable.
