Your geeky goldfish deserve better than their current run-of-the-mill home tank. If you're a Mac lover, consider spoiling your fishies with this awesome recycled iMac Macquarium ($199). Made from actual iMac G3s, the aquarium is ready to go out of the box with a working filter and lights. You can even choose from the six original iMac colors! And if you're the crafty type (and want to save a few bucks), you can order a Macquarium kit and build your own for $135.
