From what I can see they both look like they're identical...though according to the datasheet, the ANTAP281M5IB has a molex connector. I can't see any place for a 20 pin molex connector, and it doesn't look like there's any difference (certainly externally) from the photos of the two I have seen.
Can anyone share their experiences with these? (the ANTAP281M4IB is on the left, the ANTAP281M5IB on the right).
