So got my new mcr-420 and went to install it today and its different the the previous 6 I bought.

Matte black instead of shiny black.

Ports much smaller/smoother outside. And are couple mm shallower.

Casing different grade metal doesn't flex like old one's.

Overall its all improvements, just almost messed me up where ports different depths and i was using sli fittings to connect em.

Anybody else encounter new rev?

Easy to tell old ports are shaped like nuts, new ones smooth and round.
