Reusing an old Raid setup on a new build.

I have a desktop that recently had motherboard failure. Due to the age of the machine and its components an upgrade is in order. However this machine is configured in Raid 1. There's 4 hard drives in total. These drives are all 1TB WD Blue. I'm planning on ordering a new board, power supply, cpu and gpu. What will I need to do to set up the same raid configuration on the new PC once the parts are installed? I already have the data off the drives and can format them as needed. I don't see an actual Raid controller device on the board so I'm assuming its a software raid? How can I tell for sure if the machine doesn't boot? Obviously I'm a little under-armed with Raid knowledge so anything would help. My end goal is to install these new parts and get the old hard drives running normally again on Raid 1. Thanks

If you have the data off the drives, you're home free.  You can reuse the drives any way you see fit - including creating a new RAID array in a different computer.

When creating a new array on the new setup will it be necessary to buy an actual raid controller or just do it through software? And is software at what point do I set it up and how? I can load a fresh operating system onto it but does the raid array get configured before or after the OS installation?
rindiCommented:
You don't export/import the RAID configuration. Just setup the new PC with NO RAID, install your OS, then setup OS built-in RAID. That is much, much more reliable and also performs much, much better than what you get with any fake-RAID controller which is what you get built-into your mainboards.

After that restore your data from your backups.

Great. Thanks for the answer.

While I disagree vehemently with [rindi] that a software solution is preferable to a hardware solution, he's right in that you don't require a hardware controller to establish a new RAID, presuming your operating system will allow a software RAID solution.
rindiCommented:
Fake-RAID isn't hardware RAID, and that is what you get with mainboard integrated RAID, and that is NEVER worth anything. OS built-in RAID is ALWAYS better. The boards only have it because everyone has it, and because the users don't know how crappy it is.

Only some server and high end workstation boards have integrated real hardware RAID controllers, and those boards will be several 100$ more expensive than standard boards.
