Notice that one half of each raid1 is on a different controller, so if one
controller dies, you'll have a better chance of recovery.

Unless you have a recent motherboard, for older (read, pII <400), you
will probably want to get a udma >= 66.

But if you are happy with the ide on your MB, by all means, use it.  I plan
to add a pair of ide disks to my scsi raid myself.
