Fan. Same.

Platform. Same.

AC transient filter. Same.

Soldering and 5VSB Schottky. Same.

Nothing different so far.

Wait... now I see differences. The primary filter capacitance has been increased, and the bridge rectifiers are now GBU806's.

PWM controller and protection IC. Same.

The secondary side gets a little more capacitance as well, it seems. Same brand of capacitors, though... Nippon Chemi-Con. Except for the lone Ruby on the 5VSB rail, that is.

The PFC heatsink gets an upgrade on this unit. Two 24N60C3's and a diode.

Main switchers. Same.

The 12V output also gets some beefing up, with the addition of a fifth SBR30A50CT.
