You start by going into the RAID controller during POST. Create the array. Allow it to synchronize and then when it's done, begin the OS install process.
You have 4 - 73 GB drives. One will be used for parity so you will have 3*73 for total space (ie: 219 GB).
NOTE: synchronization can take a while so be prepared to wait.

Well they will all be used for parity, it's striped across them ;) .. it's just a total of one complete disc of lost space when you sum it up.
Holy Wow.

Correct. And it would be better planning to do 3 drives as raid5 and the 4th as a hot spare for instant failover.
Give a person a fish, they eat for a day. Suggest they internet search and they learn a skill for a lifetime.

Yes, I know the parity is striped across all disc's in the RAID 5 array. I should know, I've created enough RAID 5's over the years. I said it as I did to keep it simple for people reading this who don't know as much about RAID's as some of us do. If you think of 1 HDD in a RAID 5 as being used for parity, it makes the math a little easier.
