So anyway, here are the machines.
First up is an eMac:

Specs:
1 Ghz PowerPC G4
512 DDR Ram
40GB HDD
ATI Radeon 9200
CD-ROM
Apple Keyboard
USB 2.0
Mac OS X 10.4.11
Cost: Just $20 dollars for the system and a keyboard.
Second is an Indigo iMac DV (Summer 2000) Slot Loader:

400Mhz PowerPC G3
384MB PC-100 SDRAM
10GB HDD
CD-ROM
Apple Pro Keyboard (In White)
Apple Puck Mouse (I believe it's a Bondi Blue puck)
OS X 10.4.11
Price: $5 for the system, keyboard and mouse.
The eMac is in pretty good shape, it needs to have the marker removed from the front bezel, and it needs some basic cleaning. There is a slight burn in on the screen, but it's hardly noticeable.
The iMac is in pretty good shape too, the only issue with it is that it needs a slight adjustment to the CRT to get rid of some blurriness.
The keyboards are probably gonna get a retr0bright bath though, as they are both pretty yellowed.
I can't wait to head back over there and see what else I could find, he's got at least 75-100 more machines left there.
