I'm more worried about the thickness rather than length, because NZXT says it'll only fit cards 44mm thickYes easily. It can take up to 325mm (32,5cm) long cards. Nearly all cards will fit.
Would the Cooler Master NR200P be a better fit then?That's practically a 3 slot card. The H210 is limited to 2 slot models.

According to this, yes.Would the Cooler Master NR200P be a better fit then?
