I'm sure most might already have seen this, but when I was searching for info on a G5 Power Mac I recently got for free I ran across these pages still available on Apple's Malaysia website: http://www.apple.com/my/powermac/specs.html
Whoa. Blast from the past and didn't even have to use the wayback machine to be reminded that every Power Mac G5 comes with Tiger, the latest release of Mac OS X.
I have a Penryn motherboard floating around that worked, the screen was needed so it sits. It doesn't have a fan, ram, or heatsink, but I'd be willing to give it up
EDIT: Dang you live in teh UK.
A Penryn Macbook logicboard won't fit in a non-Penryn Macbook. The internet supports are different. The whole bottom case would have to be switched as well.
