Believe the case comes with 2 fans in front, both pulling air in and an exhaust fan in the back, PSU mounts on the bottom, I don't use LC except very occasionally, and not the closed loop coolers so that you'd have to decide how to mount that, most I've seen mount to the top of the case where there's some room, there was some photos in a review here:
