Hi bro ,
Mind to share how to get +25v for font panel pin1?
Just connect 2 x +12v then ok ?
Do u have photo show how to connect ? Thanks :)

I have discovered that the Firewire header on most motherboards supplies 12v on two pins; pin 7 and pin 8. I believe if you connect these together you will get the 24V that you are looking for for pin 1 of the G5 front panel header.

scare to try, later boom my PSU :(
 
6) Wiring

The Fans: This was fairly straightforward. I purchased a Y-Adapter for fans for $3, connected the front fans to it and added some braided sleeving.

I did the same for the rear fans. I took this picture before put the braided sleeving on.

Hard Drive Power: I don’t really like the way PSU manufacturers spread the power connectors along their supply cables. Why do they put 6” of cable between the connectors?

100_1342.jpg


Most computer cases have a nice rack for hard drives and the drives are mounted about ½" apart. In order to use your cables, you have to loop the cable and somehow hide 4" of cable. Wouldn’t it be nice if the connectors were about 2" apart? Apple had two solutions that they used in the G5; two power cables; one coming from the top for the top drive and one coming from the bottom for the bottom drive; and a single power cable that came from the top and supplied both drives with correctly placed connectors.

Here are the competed cables in HDD cage

The Front Panel Umbilical
Well this cable certainly isn’t long enough!

100_1326.jpg


Corsair offers a fully built Front Panel cable assembly with 2 USB 2.0 connectors, 2 USB 3.0 connectors, Sound In, Sound Out, Power LED, Power Button and Reset all for $15. So I bought one of these and just snipped off their front panel. I tossed the front panel into my useless parts pile for some future use.

100_1325.jpg


Building the umbilical took a lot of time and patience.

Firewire done

Completed umbilical connectors. That's my Corsair Hackintosh case in the background. Great case, made even greater with a well placed apple sticker!

100_1336.jpg


If you look closely, you will see that there is an extra USB cable in the mix. The USB header on the motherboard supplies signals for 2 USB jacks. Since the G5 only has one on the front, I didn't want to waste the other one, so I left it connected to the header. I plan to coil it up in the case somewhere and perhaps use it for a bluetooth or wifi adapter.

100_1334.jpg


The Power Cord Pigtail: I have ordered a Snap-in EIC Power Inlet but it hasn’t arrived yet. I plan to use this 90 degree plug and solder the Power Inlet to it (when it arrives). The one in the photo uses screws to fasten the inlet to the case, but I want a cleaner look.

100_1349.jpg


I purchased a modular power supply so I could only use the power cables that I need, keeping the case uncluttered in the process.

Very nice. I like the black mesh sheathing, makes the cables almost look like the all black G5 cables. Apple did such a good job with cable management that its worth spending the time to do the cable management correctly yourself if your gonna have a good looking hackintosh. As much as I hate to say it, your time is 'free' and the more time you can spend doing something, the less money you pay for someone else to do it for you. Glad t o see you're doing all the cables yourself, and you did a fantastic job of documenting and illustrating your work. Thanks for the posts and keep us posted... its a great reference for the rest of us!
 
7) Ascent to the Summit: Assembly

All but one of my parts has arrived. I am still waiting for the EIC power inlet and I cant complete cutting of the G5 back panel without it. I can’t cut with any of the components installed (can’t risk an aluminum shard shorting something out on the motherboard). So I decided I would do a dry run and see how all the parts fit together and sort out some cable management details.

This is almost like Christmas morning. All these parts get to find a new home inside a G5!

100_1317.jpg


I had read that some of the standoffs in the G5 case were slightly shorter than others. I hadn’t noticed this before, so I decided to take a second look. Sure enough, 4 of the standoffs are indeed slightly longer. I didn’t want to mount a warped tray, thus warping the motherboard and goodness knows what would happen to PCI slot alignment! So I removed the shorter ones and just used the 4 long ones to mount the tray.

100_1355.jpg


I then test fitted the rear bezel and aligned it with the mounted tray platform. I drilled holes into the case to mount the bezel. I bought some cool bolts to mount it with.

100_1357.jpg


Tray Bezel attached

100_1354.jpg


100_1351.jpg


Now that I had all the drilling and cutting/tweaking out of the way, I removed the tray and blew out the case with compressed air to get all the filings etc. out.
I started by salvaging the mounting screws from the old optical drive and attaching them to the new SATA DVD drive. Hey, the new drive is shorter! This is great because I’m sure I will need the extra space for power cables.

100_1361.jpg


I installed the power supply onto shelf…

100_1359.jpg


100_1358.jpg


…and installed the shelf into the case. I just temporarily mounted the shelf. I didn’t install the latching mechanism because this all has to come apart so I can cut the opening for the power inlet. I made a mistake here, (I discovered much later) when I tightened the 4 fasteners holding the shelf, I hadn’t slid it all the way to the back. This meant that the optical drive, literally the last piece I installed, would not fit into its mounts!

100_1360.jpg


I then re-installed the tray, but only attached it loosely with the two rear-most screws because I want to hide some of the power cabling under the tray. Notice the CPU power cable running under the tray right to the bottom rear corner. I also brought in the drive tray (not yet installed) and planned where its power cables would go…directly under the tray and then up through the hole in the shelf. Nice and neat!

100_1363.jpg

100_1362.jpg


Next to go in will be the rear fans (with their braided power lead)

100_1350.jpg


The rear fans are installed now it was time to add the front panel umbilical and figure out where all those wires were going to be hidden.

100_1369.jpg


100_1366.jpg


Here is a shot of the rear fans, from the rear; notice the cool Mountain Mods fan grills. I selected white fan blades for the front and rear fans to specifically highlight these grills.

100_1367.jpg


Next came the front fans.

100_1365.jpg


Finally, it was time to install the motherboard so I screwed down the tray and screwed in the brass motherboard supports. Notice that the drive cage is not installed before this step, as I need all the room I can get to mount the board. Also, since the tray cannot be removed, assembled, I mounted the CPU cooler and the memory before installing it into the case. I popped the motherboards port shield into the bezel and then carefully placed the board into position. The cooler barely fit! I might next time just install the base of the cooler and leave the fins and fan until after the board is installed.

100_1371.jpg


100_1370.jpg


I installed the drive cage next. The mounting bars made this step a breeze. They also left enough space behind the cage to tuck in wires.

100_1375.jpg


Installing and wiring the drives. Note the SATA cable positions. I am particularly pleased with how this turned out.

100_1376.jpg


And of course you need a bunch of these rail screws to mount the drives as Apple intended. Final cost? About $3 a screw. They should be gold plated at that price.

100_1347.jpg


I started to connect up the all the wires to the motherboard; first the CPU power.

100_1374.jpg


100_1373.jpg


Notice the limited space between the case and the top of the cooler…. Yikes!

100_1372.jpg


Here is how the lower section turned out after I managed all the cables. Notice the graphics card has been installed. Remember the extra USB port? Well I just have it coiled up sitting in the bottom of the case for now.
What I like about this setup is that it is nice and clean, and I am still able to add/remove parts without too much wire fiddling. I don’t have to remove panels that are hiding wires, and the wires themselves look nice.

100_1381.jpg


At this point I bunched up all the extra power cables up near the power supply behind the optical drive. I then installed, well tried to install, the optical drive and discovered the mistake I made 5 hours earlier. At this point I’m not too worried because it all has to come apart when that final part arrives. At that time I will come up with a better solution for the power cable mess behind the optical drive.
Time to fire this puppy up!

And here it is with the plastic air bezel attached. Notice my beautiful Quad G5 in the background. This new Hackintosh will look great sitting next to it everyday!

Stay tuned….This is not the end of the story!

Nice. Really love that HD cage.

Hey, on your cpu heatsink, you should position the cpu fan to the left, blowing air into the heatsink, then let the case fans exhaust the hot air hot.

I agree. If I remember my electrical theory correctly, when you combine the voltages, every point along both wires becomes 24V. When I made my cable, I noticed that the pre-built Corsair cable only connected one wire (pin 8, 12V) to the Firewire output, Pin 7 on the MB header did not have a wire in it, so I only connected to pin 8. Having said that, my firewire does not work. I plugged in a small 2.5 inch external hard drive and it didn't show up on the desktop. I'm not too concerned about this as I don't have many firewire devices, so its not going to get much use. Right now, I'm thinking of somehow changing it to USB 3.0, Somehow.

This is just coooooool!

Thanks! Somehow, I just can't take my eyes off of it.

I took a look at your mod; Nice Work! I love how you cut out the hole for the PSU fan...very professional looking. And those standoffs....do you have access to a lathe? How did you make them? Those are phat!

I debated that. Initially I had the fan on the front side, but vanity overpowered my will and I moved it to the rear; I really am in love with the look of the blue memory DIMMS. But before I did, I took some temp readings and, interestingly enough, they are in the same range compared to having the fan mounted on the rear drawing air through. The temps hover between 33 and 39 degrees Celsius while idling and don't go above 70 while running a Geekbench stress test. I'm over clocked to 4.1Ghz too. The fans are very quiet and the inside of the case is quite cool. Im looking for a memory cooler that matches my black/white/aluminum colour theme. This would be mounted above the memory, of course, and it may interfere with the airflow through the cooler.

Tanks! Yes, I have access to a lathe and a milling machine wehre I work.
