Haha. I'd buy a new G3 tower too. Though the benefits of the cooler temperature don't matter as much, it would be more affordable, yet still expandable. I have an iBook 700Mhz, and I love it. I've worked extensively with 800Mhz G4 towers, and I don't honestly miss whatever speed boost they have. But I do still need more RAM. 128 doesn't cut it. This G3 is still an excellent processor.
You happen to know where I can find one that'll slide into my B&W?
