We announced a whole new suite of Kindles today.
I've been involved with the Amazon Kindle since the beginning, and I am happy to say (once again) that I am very proud of the devices we have created.
lifehacker has a great article that explains how to get into watercooling your PC.
I currently use a closed-loop fixed system (Antec Kuler H2O in a push-pull configuration using a pair of Cooler Master Excaliburs) which works great for my needs. (But my CPU does still run a little hot when I crank it up to 4.9GHz...hmmm....)
