With Entho EVOLV TG i would recommend you to put AIO at the front with Push/Pull because that case has very restricted exhaust. Cover all the space not used by fans on top fan mounting plate. Peal mesh from cutouts at top panel, and try to remove grill that is on the back just beneath top panel.
You can pull the top panel off the EVOLV slightly and let it sit on the pegs that hold the panel in place. This might not look as sleek, but your exhaust will work a lot more efficiently. So many examples of users with high temperatures are down to poor ventilation in what are generally regarded as excellent cases. Simple changes can make the world of difference. Adding fans is what people usually go for, but sometimes removing an unnecessary dust filter can be not only cheaper and easier but also derive better results.
As far as AIO's, I'd rather go for the NZXT. The extra tubing length would be perfect if you front mount the radiator. The NZXT has a quieter pump so I've read. I think it looks sexier. And the fans are a little better this time around. Performance is negligible. The differences between AIO's at this point is price, aesthetics, availability, warranty, and noise (even then noise is often very similar). AIO's have hit their peak performance I think. I can't see them getting any better until Asetek manage to build a quiet pump as good as a Laing DDC or D5.
