I had recently acquired a 250GB internal 3.5" desktop hard drive which I plan on putting in my eMac. Of course I could go the external route, but I think replacing a 40 GB hard drive with a 250 GB drive would make more sense. How different are the upgrading instructions of the 2004-generation eMacs different from the older ones like in here? http://lancej.blogspot.com/2006/01/macintosh-upgrading-700-mhz-emac.html The only thing I'm worried about is that high-voltage CRT. Should I wear rubber gloves when performing the upgrade just in case? This is not the first time I've upgraded the hardware in the eMac. I had already replaced the old CD-ROM drive with a SuperDrive, and that went well. I also upgraded the RAM from 512 MB to 1.25 GB, but of course that's easy to do with the eMacs. Please reply with tips/info.
