Ok so I currently have an 800 g4 with a paltry 256 of ram. I am running 10.4.11 and all seems well. I really want to install 10.5.6 but seem to be having no luck getting it to install even with leopard assist. Last evening while surfing craigs I see someone has a 17" version for sale for parts only. I took the drive down to their house and found it was in perfect shape with all the accessories and the original box. I gave them 40 bucks and loaded it in the trunk. When I get home I decide for giggles to plug it in and see if it actually does have a bad logic board as they stated in the ad. Amazingly it started to the missing operating system screen...you know little folder with a question mark in it. I pulled it apart and found the combo drive and hard drive along with the bracket where completely missing...LOL. At this point I know the logic board is at least some what alive. My big question is what next? Do I bother scavenging ebay for the missing pieces?..(.found everything used for like 50 bucks) Or do I decapitate him and turn my 15 in to a 17 and pull the extra ram out and use that in the other one as well? Hell at this point it's no loss cause I ended up getting all the original acc. so my old 15 is now complete with working orb speakers and cool clear keyboard.
