I used "internal" in a somewhat loose sense. I think of it as internal
if it was intended to be in the same cabinet. Thus, a short distance
between the CPU and the drive, and the cabling do not go outside that
Now, you could have a cab kit even under those circumstances. I think
mostly of "internal" as when the whole package was delivered that way
