RAID-5 installation

I want to set up a RAID-5 set. I know that there are two different types, software and hardware. Software is provided by Windows 2000 Server and the hardware I am unsure of. What do I need to make a RAID-5 set by using hardware? I know it’s easier to use Windows 2000 Server but hardware is more fault tolerant and I just want to know what I need to have to accomplish this. Thanks, Jeremy
