Basically, the rule is that any part from any slot-loading iMac, will fit into any other slot-loading iMac. Which means that all the parts between your Summer 2000 Indigo iMac 350 and your iMac DV 400 are completely interchangable.
However, the only part that is interchangable between the slot loading iMacs and the tray loading iMac (your Bondi, your iMac 266 and iMac 333), is the hard drive.
For the record, unlike the tray loading iMacs (which have an analog/video board and seperate power supply board), the slot-loading iMacs only have one board, the Power/AV board for the display and power, as well as the Down Converter board, which is on the underside next to the mobo.
