Yes. SCSI does allow for easy connection of devices. But it takes
a little more care when setting up the booting strategy because the
PC BIOS was designed long before SCSI disks were used in PCs, or
even having four IDE drives.

I think not. There are people who clone disks with *precisely* the
same hardware (in the same slots etc.). I've not even managed it
with functionally the same hardware.

Yes. But the old machine may (or may not; I can't remember the size)
handle a new IDE drive, whereas the new machine won't, I assume,
contain a SCSI card. OK, moving that may be straightforward. OTOH
it may produce a resource conflict if the new machine is well
endowed. I can't predict.

It all depends. IDE has become very fast, but the latest variants
require good cabling to perform to spec. SCSI has always been a
bit of a pain with cabling and termination, but it's great for adding
external drives like jaz, CD-RW, etc.
