Thermaltake has a great watercooling product here with the Symphony Mini. It is easy enough for a beginner to install yet still performs well enough that enthusiasts will be satisfied. With a price tag of over $200 USD it's definitely not the cheapest solution out there but I feel you do get what you pay for. The Mini has a nice sleek look to it although the size of the unit might be an issue for some as it is not practical to move around.
