NP, dmatko, and thanks. I don't really regret buying the parts seperately. I know I could have built a better WC setup piecing it out, and the only 'regret' I could have is being looked down upon by 'hard core' WCers, but like you said, 100 bucks..........getting a GPU block in addition to the CPU block, it was pretty much a no-brainer for me. I also like the fact that I can keep my hard drives nice and cool in the stock locations (usually you have to relocated your HD's to the 5-1/4" bays where you have no airflow).........no need to cut up my case to fit a heater core. I also don't have to worry about transporting my case as nothing is externally mounted.
One word of advice: Evercool makes this same unit, but upgraded. It has a stronger water pump and the front panel has memory feature, unlike my current unit. Every time I shut my computer off the front panel settings reset. I don't use the temp monitoring feature anyways, so it's not big deal for me, but if you plan on using the thermally controlled fan header, then it is a big deal (there's still a manual speed control knob for a second fan, which I do use).
