    Hey all, I have a power mac G4 and i'm thinking about replacing the logic board.
    I'm not quite sure how i'm supposed to be going about this. I'm thinking about following this guy matt's guide. posted here.

    I was wondering if the motherboard he suggested to get (intel quad core) will be compatible with the G4. I'm not sure if the form factor is right for it or not.

    Can anyone confirm this to see if this will work? Any other information would be appreciated! thanks =)

    Not the same form factor at all. Mac Cases are not ATX. Not even intel Macs are. That guide you linked to is to build a hackintosh in an ATX case not a Mac case.

    It can be done but only if you can do things like custom mount a board and very accurately cut metal.

    This guy put x86 parts in a G4 case and also ripped off my paint job concept on my case but his is crappy spray paint.



    For the record this is the area where people ask for help with PowerPC Macs. Your request for help pertains to Intel hardware. I would even go as far as to say that this whole forum in general is not that great for anything Hackintosh related.

    thanks for your reply. so for what i want to do, would you be able to suggest what i can do?

    a motherboard that will fit in to the case, or just get a case that can fit the motherboard?

    maybe i should register for overclock.net

    First google it something like hackintosh in a Mac case. Second if you can't improv and don't know what/how you would do this... I think you should consider that.
    Also registering on some more osx86. Friendly forums *cough*insanely Mac*cough*tonymacx86* and do some more googleing suffixing with OSX 86

    Or you could continue here and possibly get banned or something :p

    Even if you can replace the logic board, you will have to replace the power supply, ram, HDD and figure out how to connect the monitor. Far cheaper to simply buy another machine.

    He obviously doesn't really understand what he is getting into in the first place. A clear case of "hey some other guy can do it so I can too" but forgets or doesn't understand that you need a pre-existing bag of tech tricks to be able to make this kind of things happen.

    A random online guide can't give you skills you don't already have.

    Im all for new people getting into computers but zen is right. You should start with something a little easier. If you want a hackintosh then put it in an atx case. Without the knowledge and experience all your gonna do is wreck a nice g4 case and probably some hardware as well.

    You aren't going to get banned for talking about hackintoshes, but this particular sub-forum is dedicated to PowerPC Macs, not hackintoshes.

    What you're proposing doing is not a logic board swap, but a "case-mod" hackintosh - you are essentially removing all of the Mac-related "guts" and sticking in a PC. It's going to require some fabrication work to install the new hardware, and you'll need a completely new PSU as well. G4 Power Macs, as zen.state says, are not ATX standard.

    You're better off going to InsanelyMac or other similar forums for info on how to build a hackintosh.

    The people that successfully do this kind of mod are people with lots of experience fooling around with computer hardware. This type of mod is far far more than simply finding the right logic board. When I still working I was quite comfortable taking PCs apart to to upgrades and find broken things. However, if you've never done anything like that don't event hink of trying to put an Intel board in a Power Mac, or any PPC mac.

    i think i'm just gona have to build a hackintosh from scratch rather than taking apart the G4. well thanks for the information

    start this whole hackintoshing project a bit slower
    as it is far more complicated then it looks on some youtube videos
    to get those hackintosh's working , and quiet often you will notice that they run older versions of leopard or snow leopard not because they'd been to lazy to press software update, no most times because after that software update the whole thing stopped working and they could not get around that
    so start hackintoshing on something where its known to cause the least problems (netbooks like the MSI wind or dell mini 10v , as those are if you ignore the atoms inside .. basically.. early MacBooks with the gma 950 in a netbook case ) to get a idea how its done to get really everything to work

    Or if you must go with a desktop try and stick to an exact replica of hardware used online in a tutorial - its not as likely to work as a netbook, but it will at least mean that your using parts that should/have been proven to work. - Also agree with the marathon comment.
