Brian:

As yet I haven't bought one, but the 3ware SATA cards sound good. 
Here's the link announcing support for them:

I'm sure I've read a posting saying they work in Alphas, but the RAID 
configuration has to be done with the card and disks plugged into a 
PC before installing them in an Alpha.
