Alright so went through what turned out to be
4 Power Mac 7100/66's and 1 Power Mac 7500/100
Out of the 4 7100s 2 had blown batteries, one so bad i couldn't even get the case off it was frozen on there and the plastic just disintegrated. 2 of them looked good internally.
The 7500 was in nice shape that will probably be a keeper since I have a matching monitor as well. I am not a big fan of this stretch of power macs though, I like the G3 I have an Indigo, and someday when i come across one of those G4s with the round base ill probably snag it, otherwise not a big fan.
The stack with the IIfx on the bottom are all casualties of battery explosions and could maybe be salvaged but i wouldnt bother. I took any relevant cards and ram out already.
The other stack with the 605s on the bottom have good looking internals, but could have other problems as none of this is tested. Most everything in that stack I will likely part with, with the exception of one of the 605s, maybe.
Up next I have 3 Duo Docks to open up, one of them with a mystery laptop stuck inside of it!
Edit: The 7500 doesnt open up from the rear like most macs before it and the plastic is very thin. I hate watching videos so I found
this website very helpful as far as opening it up and it shows how to break it all down with pictures. How it used to be before youtube...
