RAID5 sounds like the way to go. Have you ever had to replace a drive on the NAS, and was it a fairly painless procedure when it happened?

And I wanted to clarify my question about the Squeezebox clients above, too, since I worded it poorly. Here's my re-worded question:

If I was going to get some squeezebox clients, should I get the Squeezebox Touch models, or some other models? I see some older ones available used on Amazon with VFD displays. But I can get the Touch units on Amazon, Crutchfield, or elsewhere.
