Guru3D today published a review on the ECS GeForce 9800 GTX+ Hydra SLI. With this kit basically you'll receive two pre-modified GeForce 9800 GTX+ products and a water-cooling kit that is supplied by thermaltake. It's in fact the Thermaltake big water series that you can slide into you 5.25"drive bay easily.
Pretty much the only thing you need to do is connect four tubing connections, fill her up, connect some wiring ... and you are good to go. That's 15 minutes tops to get a gaming performance level better than the GeForce GTX 280.
That is a pretty easy yet high performance SLI watercooling solution folks ... don't miss the article.
