H90 and H100 are actually the same gen, just the H90 came out a little later but before the i series. So it has the rubber tubing but no Corsair link. Not like it really matters as they are all practically the same thing. Just the H50, H70/80, and H100 first gens have the plastic tubing, the rev 2s have rubber tubing, and the i series has rubber tubing and Corsair Link.
Your rear and top should be exhaust.
