I already had a Hackintosh when I decided to put my pc in one of these amazing cases, this is my first mod (not already finished) and I didn't think that it would take me so many time. The most time I spent on this was thinking about how to do it, reading posts here and figuring out how I would put all my components in it. Also I'm a student with not many money so I didn't want to spent much on things to adapt the case.

My actual PC has an ATX Mobo and ATX psu, I first wanted to put all this in the case but I changed my mind when I saw how difficult it would be and all the concessions I would have to make (cuttings, the case would not be stock) so I decided to buy a second hand micro ATX Mobo with a new CPU and ram. It was the occasion to upgrade my config and get a mobo on which doing a Hackintosh was easier (mine was a msg Z87 G45 gaming).
But I still will get my PSU and put it in the Apple cage.

The futur setup will be :
  • i7 6700k
  • Gigabyte Z170mx Gaming 5
  • 16 Go DDR4 3200MHz
  • Noctua NH-U9S
  • R9 290 tri-x (will maybe change that, it's not optimized for dual screen on Mac)
  • Samsung 860 Evo 500Go SSD for macOs
  • Kingston HyperX 120Go for Windows
  • A few HDDs


Shopping list

I'm listing here just the required things to adapt the case, everything else are pc components that can be chosen depending on your preferences
Everything is not finished yet, I will add the rest later.

Standoff adaptation

After emptying this old beast I first removed the standoff with a flat pliers and attached them on an old mATX mobo that I had. I put epoxy on each standoff and softly put the mobo in place in the case. I also used an old gpu to make sure that the board would be exactly at the right place.

Cuttings

This was the most delicate step. At the rear of the case I decided to only cut the rectangle where the ports was.
I used a Dremel with 540 discs.

This is just after I did it, I did my best and still have to clean it (grey marks on the side is just paste from the adhesive tape I used to protect it) and file it properly. I plan them to 3D-print a piece of plastic adapted for the ports of my mobo.


I did some cuttings on the ram risers cage so that it can be fitted in the case and hold the rear fan.
But it's not finished, the right side on the pic fell right on the ram slots of my mobo so I need to cut this part also.

I also had to cut the Apple PSU cage so I can gut mine in it. I don't have pics but you can find ones on NuclearLemons's thread as I have the same PSU and did the same thing


Front Panel

I just soldered the button pins to home-made cables that will be connected to the mobo
Left : LED+
Middle : Ground (connected to Power- on mobo)
Right : Power+

I won't use the original Apple front panel PCB, I want USB 3, so I will either make my own pcb or buy already made cables on Aliexpress and 3d-print something to attach them.


Fans

I simply used 120mm fans that fit on the original Apple parts

I have another one (pmw) for PSU but I still don't know if I will keep it.


Storage

There are three solutions to keep using the Apple HDD spots :
  • Buy the SAS to Sata adapter (60$ without shipping)
  • Corsair 540 Hot Swap connectors (30$ for 4 with shipping)
  • Using nothing, just connect HDD to mobo
The simpler for me was the second, cheap and I live in France so I was sure to received it (the SAS adapter is shipped from US I believe)
They fit almost perfectly using the Apple screws.

I also bought an adapter for the Apple 5,25 Bay to put 3 HDD/SSD in it.


What's left to do

  • Some cuttings on the ram riser cage
  • Waiting to receive the PSU extension cables
  • Gut my PSU in the Apple cage, won't be easy
  • Decide how I will do for the front panel ports, right up usb connectors aren't easy to find
  • Test the power button, I hope it will work
  • Enjoy

Hello, This is awesome, I just got my Hands on a Mac Pro 1.1 and have been thinking about modifying it to get an ATX in.
Please keep us updated on how this goes.
Cheers,

Thanks !
Adapting the case to an ATX mb required more cuttings and more work that I didn't have the courage to do.
I encourage you to take a micro ATX mb if you can it will be much more easier !
I first wanted to just find a Z87 mb to replace mine an keep my cpu and ram, but it was difficult to find and not worth it so instead I bought a new mb + cpu + ram at a really good price

The work of today was finishing the cuttings on the ram riser cage

It's now fully adapted to my mb. The upper part don't touch the ram sticks, the part below touched one of the ports.

I also do some cleaning and filing on the back

I'm now working on a 3d model to cover this hole
