There usually is a place in the front, at the bottom, under any drive
bays. If you have a spot in the back of the chassis, they may not have
punched the holes for the front one.

Computers like to stay cool. Having said that, there is a diminishing
returns aspect, as well as a loudness aspect, which is wholely up to
you. I have seen cases where the cooling was performed by a fan on the

Simple methods: Any screw large enough with coarse threads that can "dig
in" to the plastic of the fan. Or, a long thin bolt and screw method.
Maybe some washers to provide coverage of the holes.
Less simple, but kinda cool:
