The S has better air flow as long as you only need 3 3.5 hdd mounts or less. There are no hdd cages that will block any front fans.
I prefer the R5 after building both for other reasons like the lower filter sliding out the front, included fan controller and 4 usb ports instead of 2.
Its also nice that a 240mm could fit in the bottum. The S can only fit a 120mm there.
Also I noticed the 140mm rear fan mount is slotted on the R5. Very nice if you have a rad up top the rear fan slides down to a more effective location.
The S has only one rear fan location.
IMHO the S is simply the budget version of the R5 with some reservoir mounting.Edited by Wirerat - 7/8/15 at 7:03am
