aquacomputer w/cooling kit

[SiD-P]

I am also thinking of water cooling my rig, I have been looking at a various water cooling solutions available and as this is my first W/C setup I think a kit will be best for me.
I have found one kit I really like, the AquaComputer High End Kit with Cuplex XT CPU block.

I have an E6600 @ 3.2 (355*9, stock Vcore), cooled with a Tuniq Tower 120, my temps are:

idle
Asus Probe 26-28c
CoreTemp 40-42c

load
Asus Probe 38-40c
CoreTemp 50-53c

P5W DH Deluxe & Tuniq Tower 120 @ 1650rpm.

Will the AquaComputer water setup better my current temps?? and if so by how much more?

Are there other kits on the market that will look as sexy as the AquaComputer kit in my Lian Li V1000 black?
