I was also wondering if the power supply & case of a G6-350 could support a Pentium 3 or 4 motherboard- seems like it should be able to
It is possible, though unlikely, that the case and power supply will work with a Pentium III motherboard.
It will not work with a P4 motherboard--the P4 motherboards have an additional (square) power connector and require high-capacity power supplies. A PII power supply, even a good one, won't work with a P4.
Does the computer have a keyboard connector that is a large round connector, or does it have a very small round connector that's about the same size as a Macintosh ADB connector? If it has a large connector, you have an old-style case and power supply--will not even work with a PIII. You'd have to replace everythng, including the case and power supply, to upgrade that machine.
