Does anyone have a picture or a URL with photos and a description of parts/brackets that I need in order to mount additional hard drives on top of the two bays at the bottom of the machine? If someone can tell me what to request, I'd post a WTB on the lem-swap list. Thanks, I would suggest that you try to find a "double drive" bracket that fits on the extreme right side of the interior of your G4. This bracket will mount two drives on the same location in the case. One drive mounts directly above the other. Then, you will also need a IDE ribbon that has TWO connectors at one end so you can plug into both drives with the same ribbon. Once you have the bracket and ribbon installed, make sure that you have identified the drives as separate identities, ie: Master on one and Slave on the other, before trying to startup. Use an OS installation CD to reformat the drives and install the OS that you want on whichever drive you intend to use as the boot drive. You could do an OS installation on both drives which would give you the ability to boot to either if needed. For any additional drives to be installed in the case, you will need to buy an ATA IDE Controller PCI card. Be sure to get a card that is compatible with your machine and the ribbons needed to connect to the extra drives. I have been using a Sonnet ATA-133 IDE card for over 6 months with no complaints other than the fact that I had to buy the connector ribbons from Sonnet in order to mount a third and fourth drive in my G4 GBit Ethernet case. All the above is predicated on the idea that you are going to install NEW drives in the G4. If you intend to continue using your old drive and just add more drives, most of the information still applies except for reformatting the drives. You may not want to lose all your existing data, yes? Another thought is - Why not simply replace your old drive with a new and larger one if all you need is more space? Put your old drive in an external FireWire box and keep all your data as a backup. That way, you could still have your cake and eat it, too. A third thought is - Install the new LARGE drive in the second mounting location of your case and just use a new IDE ribbon to make the connection to it and your old drive. Your box has enough power plugs to do this without having to go to a lot of expense to buy cards and ribbons. Hope this gives you some ideas that won't cost you more than you want to spend.
