FOR SALE or TRADE: iMac G5 1.8 GHz 20 in: (M9250LL/A)
Replaced PSU with working used one from 100% positive-rated, 4.7K items eBay seller intellitec23. Successfully installed Lubuntu 16.04.5 without encryption or LVM, since Apple abandoned PPC OS support. I've spent more time & money than $100 restoring this as far as I can, overall. Has 160GB SATA HD, 4X "SuperDrive", 2x256MB RAM, basic black power cord, Apple-branded power cord, an original CRT iMac keyboard (model M2452, teal) that passed on keyboardtester.com - you clean it out.
