Upgrading an eMac

Apple has three generations of eMacs. Your chance of ever seeing one for cheap is probably fairly limited except for on E-bay, but there is a site where you can hack your eMac to your heart’s content. Upgrading hardware is never something for the weak of heart, but just get those defibulators ready and you’re good to go!
Go nuts here!
