FoxyKaye, Where are you sticking that fourth HDD? I know theres room for three on the bottom, but where is your fourth located? Did you get the drive sled from a Rev.B? Can you post pics?
Im just trying to decide to stick my fourth drive and im kind of at a loss at the moment..
Actually, it is nothing that complicated - My Blue/White is one of the *early* revision 1 machines, so the mounting points for three of the drives are plates that screw into the bottom of the chassis. These three drives I run off of the ATA/133 card (the 60, 80, 100 GB drives).
Since I didn't want two drives on my second ATA/133 channel (this is the drive where I keep all my MP3s, and I've noticed that other activity on its channel tends to make them skip when playing), I used the ATA/66 channel that is on the motherboard itself (to which the machine's original IDE drive was connected).
My machine doesn't have a Zip drive, so my fourth drive (30 GB) I slipped into the chassis for the Zip drive and connected to the motherboard as a single IDE drive on its master channel (the DVD-ROM is the master drive on the motherboard's secondary channel). You'll need to purchase some extra long 80-wire IDE cables to pull this trick (I've routed them so they don't block the fans), and a 4-pin power cord extender helps too.
Actually, I've also considered adding a 5th hard drive using the extra slave drive position on my ATA/133 card, in which case I would mount it above the CD/DVD chassis (there's about 1.5" of space up there). But at this point running all that cable seems daunting.
Note that I've also added some extra cooling to the system: the G4 processor heat sink has a fan mounted on it, and I've also installed a PCI fan I bought from newegg.com for like $8. Apple doesn't recommend using the empty Zip drive opening for a hard drive because of cooling issues, but I've never felt anything but lukewarm air coming out of any vent on the system, so I figure I've got this down. If cooling does become an issue for the 4th hard drive, I've had some success attaching old Pentium I heat sinks to hard drives with thermal goop and adding a fan behind them - in which case I might consider removing the front plate of the plastic cover over the CD/DVD drive and empty Zip drive space to facilitate cooling.
Hope this helps!
