G4 Cube Upgrades

Are you kidding?!?

Absolutely. You can theoretically put in any 3.5" hard drive unit, although a 120Gb should be more than enough. I'd put in a 5400 RPM instead of a 7200 RPM, because it's quieter.

Of course, if you're planning on upgrading the graphics card, it won't matter - you'll need to put in a fan anyway. The Cube can go as high as a GeForce 3, which should be great for any application. However, rumour has it that somebody squeezed in a Radeon 7500, albeit with a little doctoring of the card's PCB! Bear in mind, though, the graphics card WILL increase the heat and noise from the onboard fan.

A good site to investigate is www.cube-zone.com which has some good links for installation guides.

And finally, eBay is perhaps the ONLY place to get an OEM GeForce 3 ADC now, as they're about as rare as HENS TEETH (and that's reflected in the going price - expect to pay up to $300!).

Good luck!
