There appears to be space on the left side (the side towards the front of the case) but there is no bracket. Where would a purchase a second bracket? I would probably have to add a wye connector for the power. But the other issue is, how do I install a second DVD? This issue is NOT connected to adding the third hard drive. I want to put it into the hole for the ZIP drive, which directly underneath the existing CD drive. Rich, Look carefully at the chassis bottom to the left of the double drive bracket. You might see a small phillips head screw located near the edge close to the hinge. There were two such screws in my chassis and the additional plates were held down by them. The additional drive mounting brackets are flat metal plates with holes for the mounting screws and do not look like the original drive mounting bracket. If the extra mounting plates were removed before you got the machine, you may be able to locate one or two through a local Mac User Group member or on eBay. Yes, you will have to use a Y adaptor for the power source to the extra drive if you have already used all the original connectors for other devices. The issue of installing a second DVD is another matter. I resolved my desire for another drive by buying an external USB/FireWire box and installing a Pioneer 105 drive in it to match the 105 installed in the internal 5" bay. By doing it that way, I can use the external drive with my Lombard and Pismo laptops, my G4 Gbit, or my "old" Beige G3 DT, whichever one I decide to start up. I decided that it was cheaper to do that way than to hack up my sub-chassis and maybe do something too wrong to correct later.
