These are the regularly used ones for LANs etc. Some more are stored in their original boxes, others are ready for restoration. I now own at least one ex of each series of desktop and mobile G3, G4 and G5 since the iMac G3, except the Clamshell iBook. They are either in bad shape or ridicilously expensive.

My first QS had a ZipDrive. At least mine had a special plate like this one

Unfortunately my only Zip-Mac now is a B&W G3.

That's the reason i don't recycle but restore them. The eMac G4 is an absolute pain, that's true. I had to open it to swap the HDD to a SSD. Can't recommend...
