6500 Motherboard in a Performa 575?
It should, yes, but it won't work. The 6500 requires 3.3 volts, but the Performa case and power supply doesn't provide that. If you wanted to do something like that, you could make a 3.3 volt regulator and attach it to the 6500 motherboard like so:

My motherboard isn't a 6500, but it's close. My guess is that it's from some sort of 6360. I found the motherboard in the trash in NYC many years ago and transplanted it into a Quadra 630 case.
There is an exception. The hack *MUST* be done for the 5400 board. However, the 5500 board will work *WITHOUT* the hack, but there might be issues with PCI. I'm not sure if this is true for the 6200 or 6300, but I was able to pop a 5500 board into a 6200 and use a USB PCI card. I haven't read if the 6x00 machines needed this hack, but it worked without it.
The hack is a must for the 5400 board, though.

Interesting discussion thanks for all the info. My main goal though is to find a motherboard other than the 575 board that I can put into the 575 chasis. Because the 575 motherboard is going in the Color Classic. I asked about the 6500 motherboard, because I can purchase it online for cheap.
