Seems to be a nice unit...
Review
but getting all the parts and doing it yourself is definitely cheaper and you can get better parts as well..
Looking at my primary rig....
Swiftech MCW5000-P Waterblock: $49.00
Black Ice Extreme Radiator: $68.00
Eheim 1250 Pump: $66.50
120mm Panaflo Fan: $15.00
Tygon Tubing: $15.00
Bay Reservoir: $25.00
Total:
$238.50 (Not including clamps and shipping)
The Corsair HydroCool costs less with free 2 day shipping to boot.

It can also be used on either AMD or P4 processors.
EDIT: Not to mention that the HydroCool needs very little (if any) real case modding to install...
EDIT: The
Overclockers.com Review looks good also.
