UPDATE
February 19th: my motherboard finally arrived for me to install OS X.

I wanted to approach the installation process by setting up everything using the just the very PC I was building without the need of another Mac and I was capable of doing so. Started out with installing 10.6.0 and was able to update to 10.6.8 with iBoot Haswell 1.0.1.

The main issue I had was the method I had to go about installing Mavericks, 10.9.0. I almost gave up, but after venting on this thread here and with a little motivation, on March 5th, I was finally able to install Mavs on my EVGA Z87 FTW, and I have a full-length guide that details it all here.

February 27: My G5 "120 low ATX Mod kit" from the Laser Hive (based out of the UK) finally arrived (thanks Neil for the referral).

I didn't immediately get started on modding my G5 case yet until I was confident that OS X could be installed using my motherboard.

March 14: Let the games begin! I had to get my tools first.

Next, I measured and marked off what part of the back of the chassis will be removed and I also pulled out the PCI slots.

After much deliberation, I decided it would be smart to be conservative about how much I would cut off during my first attempt, turns out I happened to make the right decision.
13302954603_bdb768483a_b_d.jpg

I had realigned the back panel to measure how much more I needed to cut from the chassis. I was almost on point with my first attempt.

March 15: In the wee hours of the night I continued to finish the mod by attempting to mark off and then cut off part of the front of the chassis for the front I/O panel.

Then I had to shorten the stand-offs for the motherboard tray.

When I initially aligned the motherboard tray with the chassis, one of the stand-offs didn't line-up with the tray's perforated design so I removed it, leaving only 3 that could be used. I wanted to reattach the one stand-off so that it could also fit the trays design. I applied JB Weld to attach the stand-off.

After waiting 9 hours, I felt it was dry enough for me to shorten the stand-off with a dremel so it could fit the motherboard tray. Unfortunately, the dremel moved it out of place and impatient as I was to finish, I decided I would stick with 3 and just wash the chassis so I could finally screw on the back and front I/O panels.

Back panel screwed on... I hadn't ordered a back fan yet, so with a little improvisation, I used cable ties to hold the screen/grill in for the mean time.

Front I/O panel screwed on...

Lastly, I had to reassemble the top shelf, door lock mechanism, and hard drive bay before I could screw in the motherboard tray. Unfortunately, I had initially ordered the wrong size CPU heat sink so I am not able to attach my motherboard in the chassis just yet until my new heat sink arrives in the mail. I will also update my log when that happens.

March 20: For all the folks out there with Haswells, especially the 4770Ks, I decided to do the unthinkable and de-lid my CPU. After watching a few YouTube videos, I had ordered myself a syringe of Cool Lab Liquid Ultra, and then I completed the process.

UPDATE
On March 22, my new CPU heat sink, the Noctua NH-U12S arrived so I was able to attach my motherboard in the chassis. After assembling all the hardware in the chassis, I was able to fire it up. Now I have a fully working hack (10.9.1) that looks like a Mac. Some more good news: after the de-lidding my CPU, I did notice it was 4 degrees cooler than usual. There is still some more work to do before I feel my system is completed, but at least the hard part is done.

What do you have running in the hard drive cage, above the hd?
Above the Velociraptor disk drive, I'm using a Patriot Dual Bay 2.5" SATA 3.5" drive bay with (1) OCZ Vertex 4 512GB. It was turned backwards because its cabling caused it to protrude past the drive cage's lever that holds it in place. There's also room for expansion if I wanna add another 2.5" disk drive. I was unhappy with the position of the PSU so I switched out the PSU shown with a smaller one and remounted the hard drive cage under the top shelf where the blu ray drive sits which I notated here.

I have one small issue though. I created an external eject button for my blu ray drive to open. I screwed the drive down in place but when I press the eject button, the drive tray gets stuck. Is there a certain height in which the blu ray drive should stack against the door?

Have you removed the fascia plate from the blu-ray drive door? If not then try that as that is a necessary first step.

If it still sticks after removing the plate from your Blu ray drive then you can try unscrewing the little drive feet and putting in a washer between them and the player to act as a shim to raise the drive very slightly. The G5 drive bay door can be a little fussy about drive height. But play around with it and all should be solvable.

Frank as minihack has indicated, the optical drive front plate needs to be removed; see this thread, post #27, http://www.tonymacx86.com/powermac-g5/103966-qqat-quick-question-answer-thread-powermac-g5-hacks-3.html

And there is a link in that posting to a video instruction to removing the part.

The Apple screws look like this photo:


And key here is the height of the drive. You can use washers to space up your drive to get the proper door action.

Good modding
neil
minihack and neilhart I wanna say thanks to both of you. I have already removed the bezel and I reattached the lever used to hold down the drive and I will be going out later to retrieve the the Apple screws to mount the drive.

Couldn't find the screws locally so I just ordered them online here.

My optical drive mounting screws arrived and I didn't realize magnets were incorporated in them.

I just finished setting them up and now my optical tray can release. My G5 mod is fully complete.
