Had a MBP 2.26 with a dead motherboard and a second one that was seriously wrecked (screen) by a friend during a violent car crash. Made one functioning MBP 2.26 out of two by swapping the good "organs" in the MBP that was not wrecked :-)
Fine, thanks' to iFixit guides !
iFixit "Pro Tech Toolkit" helped as I had all the required tools
