[Lonely Raven]

I tested stuff for Leufken about a year and a half ago. My
opinion on his stuff is this.

It's inexpensive, does an acceptable job of cooling, and is as
reliable as the quality of the assembly.

I've got one of his original Rio pump based resovoirs and it's
been running for almost two years...honestly though, I think
I'm just very lucky...those little pumps never seemed too
powerfull...but mine keeps pumping along (although VERY
slowly).

IMHO, it's a great setup, if you just want to do as good or
slightly better then HIGH END AIR cooling, but without the
buzz of the fans and not invest in SERIOUS water cooling.
Which is pretty much what mine is doing now...
