I have a G4 cube with a 17" Apple studio CRT display (clear plastic), and a new apple Key board. The Cube power converter is starting to go bad. but I have it on life support with a small fan to cool it. There is this guy with 2 Power Mac G5 computers for sale. This is one: -Dual 2.7Ghz PowerPC G5 -ATI Radeon 9650 256MB VRAM (2x DVI output) - 1.5GB PC3200 RAM (Upgradable to 8GB) -200GB SATA Harddrive -DVD-RW super drive -Mac OS 10.5.8 -All software up to date as of 10-29-2010 This is the other: -1.8 Ghz PowerPC G5 -NVidia FX5200 64MB VRAM (1x DVI output 1x ADC) - 1.5GB PC3200 RAM (Upgradable to 8GB) -200GB SATA Harddrive -DVD-RW super drive -Mac OS X 10.5.8 -All software up to date as of 10-29-2010 He says one will work with my display: the 1.8Ghz, but the other won't because it doesn't have the right graphics card. I plan to buy a Macbook pro, but I would still like to have a desk top, and this way I could use my keyboard, mouse and display. Could the faster unit be made to work, and what are they worth? The computers came from government offices. He gets them and puts new hard drives in them and sells them. I think the old hard drives are removed for security reasons.
