How to fit PC in a G5 PowerMac enclosure :> Options

[teknojunkie]

So can anyone show me a pic of the Front panel board connected to the motherboard

[nylock10]

Well You can buy a cose enough motherboard to do that but the easier way is if you know how solder, then you can desolder move and tweak them to fit into them. But I suggest cutting the back and getting a MotherBoard Tray so if you ever want to change it then you can.

Yeah actually I might just get a dremel and carefully cut out the back (just enough to get a plate in there), I don't like the idea of soldering (I wouldn't know what I was doing).

But, has anyone gotten the front I/O powers to work (and if so - how?).

I'll probably use an ASROCK 1333 D667 motherboard.

So is thier any one with a picture of the front panel wire connected to there motherboard

guess not, you getting progress on your case done though?

Trying to figure out all the wiring first here is some pics of the power wire of the front panel and fans

Here is the Front Panel Wire


Power And Led Button Wire From Two angles. Three Wires



Alot Of fans, Trying to Use all of them


Connector of one of them any ideas people, Habit of bitting nails nasty huh? And Front View Of it



The BiG one

Connector For It front and back again any ideas?


The Fan With the speaker also can I make this one have the apple chime when I start it up huh again any ideas lol more angles too




And Thanks Really need your guys help on this

In this thread , the author show how to connect the HD's fan. I have to look for the comment . Here we are post 43 to 47 on page 3, you will find the answer.

you're better off just buying atx spec fans and building some brackets for them, rather than figuring out the wiring on the apple fans. that would be a major pain. not to mention getting the temp and rmp sensors to work right, don't forget that, cuz if the apple fans run at 100% all the time, they'll be hella loud, and probably burn out kinda fast

Yea I saw that but I dont really know which wires connect to which wires on Mob, Im basically looking for a diagram of each pin on the fan so I can match them up with the one on the mobo

Yea I know I want it to be as original as the powermac G5 case I dont care really if its loud and I will find a way to get th sensors to work

[teknojunkie]

So for the wiring of the Front Panel I can just use the wires on my other pcs front panel wires or where i can buy the wires like

Usb on G5 front panel = usb internal wire

Firewire on G5 front panel = Wire to connect to motherboard

Power and Led Wires = Wires for them to connect to motherboard

thanks

I found this pinout...

Thanks so much so can I just use the front panel wires on my pc and solder them to this

[maclust]

ok, i have taken the standoff's out of the case and can no longer find them so do i epoxy the mobo tray to the side of the case or putty epoxy it raised about 1/8-1/4 inch. i also detached the mobo tray from the backing it came. i am going to epoxy the tray and rivet the backing to the mac case.

I found this pinout...

OK, guys that is a photo of my custom front cable there based on the official pinout diagram....I finally got around to testing my new cable. i just used the G5 front panel to boot up an old shuttle, and my initial suspicions were just confirmed:1. THE FIREWIRE AND PWR BUTTON ARE SOMEHOW BRIDGED ON THE APPLE FRONT PCB!2. You DO NOT need to run a ground cable for the power button header on your MOBO, it is somehow grounded through the firewire voltage return.3. Pin 1 is FW + voltage, and pin 2 must be used for the FW voltage return (true ground, not chassis ground)4. if you have installed your usb and firewire correctly, then you need only a power+ and a pwrLED cable connected to the front panel header on your atx motherboard in order to power up your machine.5. The PWRLED wire and PWRBTTN are reversed. I connected the LED wire to my power button+ header on the mobo, and my power button to my power LED header on my mother board and then pressed the g5 power button and my machine powered right up... I have revised the diagram I posted earlier. it is updated with my current findings.I have not fully tested the firewire and usb connections yet, so stay tuned for the final word....

another update:

with power on/off working great i started testing the front USB port.

usb devices that i plugged in would be initially be detected but just not work. the best solution seemed to be the reversal of the data+ and data- cables.... and it worked perfectly..... so on my setup, i have followed the USB pinout, except at the motherboard end i have flipped the data + and data -

coming right along......

now onto the firewire......

[aqua-mac]

Nervouschimp,

When you get to the firewire you may find that one of the data cables needs reversing from the diagram too. A good year since I did mine!

thanks for the heads up, and your are indeed correct. just like with the USB, the data lines for the firewire must be reversed, as well. so TPA+ and TPA- must be reversed, and then TPB+ and TPB- must be reversed. i tested this setup using a Lacie firewire hardrive and doing several data transfers... it's working great.

i updated the graphic above to illustrate the correct pinout.

also, to verify that the power button is grounded through the firewire VGND, i unplugged the firewire, and then tried to power on the machine... no dice... the firewire VGND does in-fact complete the power button circuit so it must be used.

now i haven't gotten around to the front audio yet, and may not any time soon.... but anyone can use my last diagram posted above to get all up and running.....

so there you go.... that's the pinout you've wanted....

Do you have any pics of your front panel connected to your board and thanks for the picture really helps alot

[teknojunkie]

Ok now I know How to get the Front Panel running now how about the fans

[teknojunkie]

More Stuff came in

Guess what Im making 2 and one of the mobo was not working and need to send it in

























More Parts are coming in and also do any of know where to get the female power thing thats on the front of the powersupply where you put in the power wire or a female to female plug I don't want to open up the powersupply. Thank you and getting one mobo RMA'd stupid Abit and can I use a video card in a PCI E x16 electrical x4 slot thank you and I want to try doing this SLi

[HacOSXuser]

hey that motherboard looks like the g5 one in color haha.
