Liquid cooling for phenom II 720 x3?

any systems?

Custom, is all you need to know.

I agree, if you want to get the job done properly you'll have to set it up yourself.

your going to liquid cool a phenom 2 x3 720 ???..

is this like a recent decision?

Yeap. Those "sets" are same level as very good air coolers. For the watercooling to be goooooood, you need a custom set. with only the good stuff :]
