Windows Server 2003 Software RAID 5 failed and System Disk too

Hi!

I have serious problems with one of my servers since we had several power outages.

First a disk of a Windows software RAID-5 with a total of 3 disks failed so the array was degraded. On the disks were 2 RAID-5 dynamic disks just for data...
Even before I got the disk for replacement my system disk also failed.

So here is my question:
How can I recover/rebuild the data from the two RAID-5-dynamic disks?
Can I just connect them to another system and they are detected automatically? Or are there any caveats?

Thanks so much in advance !
