I have to throw my 2 cents in. I've twice fallen into what at first appears to be an easy mobo swap, and then turns into a disaster.
The first time, after reading they had the same form factors, I bought a Quadra 800, an 8500 mobo, and an 8500 back panel, and an 8500 AV module. Although I was wise enough to realize it needed a different back panel, I didn't realize that because of the internal plastics, the 8500 panel woulnd't just slide on nicely. I kept trying to think of something but I would have needed to buy an 8500 case negating almost any value of buying the 800 (especially since the 800's P/S was DOA), and would have left me with an extra back panel. The second time I again thought "This is so easy, why didn't someone else come up with this..." In this instance I was going to replace the motherboard of my 7500 (which I eventually bought to replace of the 800/8500) and put in the motherboard of a Beige G3/300. The cases on the outside looked the same, right? After getting the board, I took out a saw and cut up the back of my 7500. Then, I ripped up all the pieces of plastic that hold the mobo to the case. After laying the board on the bottom of the case (with the back off) and trying to connect everything, I realized the Power Supply was different. Finding a P/S from a desktop G3 was a pain, but I eventually got it and after more cutting of the back panel everything fit. Unfortunately, the mobo never was secured to the case; the part with the drives simply laid on top of it. Putting down an empty soda can on the desk would cause it to freeze. After taking out the PCI slot cover it ran a little better (I have no idea why), but it's always been a pain. Today, I'm two paychecks away from a Dual 867 G4. I hope I didn't discourage you, but after trying twice and putting a lot more money than I would ever care to admit into it, I've sworn off project-macs as my main computer. BUT, if you do get it working I've got a friend whom I could maybe convince to do it to his (with his money of course).

I have a B&W G3/400 which, AFAIK, is a similar case. Would it be possible, does anyone know/think, to fit a G4 logic board in amy G3 instead of buying a new G4. To get one and a G4 to fit it is less than buying a G4 tower system complete, I think. My theory is you buy a G4 logic board and a Powerlogix upgrade and slam em in my G3 and you have a real AGP 4x G4 in a retro B&W box. Anyone know anywhere in the US that sell them off the shelf at a reasonable price?>> -- G-List is sponsored by <http://lowendmac.com/> and...
