RAID0 is called striping and it writes half the data to one hard drive and half to the other. If that drive is totally dead then the only way you can recover it is to send it to a specialist. This is why you should backup your important data often, or run RAID1.
As a hardware guy I can't help but ask these questions, forgive me:
Does the hard drive spin up? If not, then the electronics are dead. Its possible if you found the electronics from an identical drive you could swap it out and copy the hard drive to another drive.
If it does spin up but clicks, you might be able to toss it in the freezer over nite and quickly read it off the next morning. IBM (Hitachi) Death stars were known to be able to save a lot of data that way. Its a total shot in the dark and could cause more damage if its dead because of a head crash.
If I were you I'd buy new hard drives and run RAID1 on a fresh install. I have two raid1 setups in my server and my laptop runs raid1. I don't trust hard drives any more. I've lost too much data.
I don't think the respawn kit will work with the new motherboard. I suspect its got all the drivers needed for the old mobo. I think you need a windows XP install disk.
