The pics on the Enlight site are old, later revisions have a stamped grille for a rear 80mm fan. The 7237 begs to be modified, particularly the front bezel. If you're not into that, get the Fong Kai for better stock cooling.
With any case, particularly an Enlight 7237, having a rear exhaust fan is extremely desirable, even if it is a low power model like a panaflo L1A. Some cases will do just as well with only a front intake fan. At least one each for intake and exhaust is what most "enthusiasts" would recommend, although it's easy to get carried away and end up with an annoyingly loud machine.
