sawtooth

Would love some help with this since I am probably missing something simple. I'm having trouble with two AGP PowerMac G4 Towers, one Sawtooth and one Quicksilver. Both had been upgraded with Sonnet CPUs and work fine with those. I ordered replacement CPUs that match the machines original specs...

I found an old heat sink that I extracted from an old PPC PowerMac of mine and I'm trying to identify which PowerMac tower it came out of. I can't remember. I believe it was a G4 tower. I think it came from either a Sawtooth or a Quicksilver G4 tower. I can't find any photos of a Sawtooth heat...

Currently I have 3 HDs in my G4 Server, but one of them is in the zip drive bay. I want to get it out of there and maybe add another drive, but I need an IDE controller. Are there any good, inexpensive options?
