That is insanely nice. The Lian Li PC-A71 case works out really nice for water cooled setups. If I ever get around to buying a new case (I'm fairly happy with my Cooler Master RC-690), I can see myself getting that case and doing a fairly similar setup.

If you do a second loop, where are you thinking of putting the radiator for it? Mounted off the back fan mount with a radbox?
