The aluminium rads are super cheap these days.  Watch what you are buying as quality varies.  That said, copper rads cool better at low air speeds.  If you are send out the rad to a rad shop, they can easily plug off the TC switch fitting and solder on an S2 one (M22x1.5).  Myself, I prefer the rad fans switch being on the outlet side.
