I found a IIci at the tip today (and keyboard/mouse). I started it up before attaching the screen (via 6-pin adaptor) and it sounded like it started up perfectly. While I went to collect the monitor from inside the house, my room filled with acrid plastic-smelling smoke, and the power supply is surely fried now 
It is a shame, as it was maxed out with RAM. Sadly, there were no "standard" connectors inside whatsoever (good one Apple!). I had a spare Cache Ram chip somewhere, but that is all over now.
I'll keep my eyes open for more.
On an unrelated note, I fixed the DVD burner in my 700MHz G4 iMac. I think I knocked the adaptor power out when I sealed it back up.
