Matt,

What you've got is a parts machine which probably has a logic board suffering 
from the bad capacitor plague that affected most iMac G5s. If the iMac still 
chimes and attempts to boot before it goes into "vacuum cleaner mode," there's 
a good chance that replacement of the 25 or so capacitors on the logic board 
will restore it to life. But there's also a chance that it won't, especially if 
failing caps managed to damage video circuitry. Your iMac also could have a 
problem with the video inverter if the screen won't light up.

If I were you, I'd first try to sell it locally as a parts machine. Failing 
success there, I'd then offer it to LEM Swap members as a whole machine. If no 
one wants to pay the shipping charges plus a modest price for the parts (LCD, 
optical drive, hard drive, RAM, bluetooth/Airport/modem cards, power cable, 
fans, etc.), then I'd part it out. Of course, having the original Apple 
shipping box will make things easier all around as the LCD is a delicate piece 
of equipment that can be damaged all too easily in transit in a non-Apple box.

I've successfully revived several G5 iMacs and eMacs by replacing capacitors on 
the logic board as well as in the power supply. It's hard work because Apple 
started using lead-free, high-temperature solder which means hobbyist-level 
removal/replacement of caps isn't easy.

Good luck!
