COMMENTS

I was given a 2004 Power Mac G5 last year, it had been sat in a cold damp basement for over three years. I'm a big fan of this case, many, many years ago our college graphics room had 12 of them all lined up, it was an awesome sight. It wasn't in good shape, booting was random or the fans just spin up. Ebay came to the rescue with the purchase of Power Mac G5 installer disks, Mac OS X 10.5.3 Panther. I was able to clean install Panther and got some screen shots before the capacitors gave up.

I looked through tonymacX86 excellent PowerMac G5 Case Mods Forum, to get some ideas about building a Hackintosh inside the G5 case. One thing that struck me was, why are they cutting the case?. After reading Petri Chron's thread, Super-cheap NVMe fusion drive using Dell 7010 Q77 motherboard. And trs96 [Guide] Install High Sierra or Mojave on the Dell Optiplex 7010 / 9010 Desktop PC - Revision II. I set about building a Budget G5 using a Dell 7010 mobo.


I enjoyed this project enough to want to upgrade it and create a Windows gaming build and a macOS that can handle Affinity graphics Apps like Photo and Designer, I also use Glyphs, a Typography Creation Tool. The H370M D3H GSM motherboard was the part I spent the most time researching. It's a mATX board and it fits perfectly under the top shelf of the G5. The PCIe x1 is accessible when the PCIe x16 is full of graphic card. You can fit 3 NVMe SSD on this board, two in the M.2 slots and one via an adapter in the PCIe x4 slot. I haven't used the M.2 CNVI slot yet, but I have been reading about it on these forums so I know it's a possible upgrade in the future. That's another consideration too, Future-proofing!. I'm sure I'll still be using this motherboard for years.

BIOS

I have commented on the changes I made in post #78 of this thread. To access BIOS you press DEL key on startup and this will send you to the BIOS home screen. Following this guide Unibeast: Install macOS Catalina on any Supported Intel-based PC. In step three of the guide, Recommended BIOS settings, I made the following changes.

Load Optimized Defaults. After this I saved, exited and restarted back to BIOS.
  1. If your CPU supports VT-d, disable it.
  2. Set OS Type to Other OS.
  3. If your system has IO Serial Port, disable it.
  4. Set XHCI Handoff to Enabled
  5. Save and exit.

INSTALLATION

Following this guide, UniBeast: Install macOS Catalina on Any Supported Intel-based PC, with UniBeast 10 I created my USB installer. Make sure to choose APFS as the format in Recovery/Disk Utility. HFS will not work.


MULTIBEAST 12.1.0 CONFIGURATION

Drivers>Misc>VirtualSMC is already installed when using UniBeast 10, It's normally greyed out on the Drivers page.

CLOVER CONFIGURATOR

In this App I changed CsrActiveConfig from the default 0x3 to 0x67. This disables SIP.

WHAT DOESN'T

Working on Messages, Facetime and Hand Off.
Although I can see SideCar in System Preferences, I'm not able to test it. I have a 1st generation iPad mini. It won't make you a cup of tea unfortunately, I've asked numerous times.


UPDATE

I currently have macOS Catalina 10.15.4 installed, post #120. I updated easily from System Preferences. Clover 5107 boots much faster than 5102, less pausing in the progress bar.

While waiting for metal cutting tools to arrive, I modified the original G5 PSU enclosure by screwing the bottom shelf directly to the base of the enclosure, yellow circles. I left the top of the enclosure off, it was unnecessary, heavy and would of meant cutting the same hole twice!. The bottom stand offs for the heat shield have dropped by 1mm which I'm happy with because the shield will be secured firmly.

It's easy to place inside the G5 with the rear fan guard removed. The red lines mark the area which will be cut to fit the CX750M PSU.

really pleased to see the new motherboard inside the G5, everything lines up perfectly. 5 standoffs that we’re used to attach the Dell 7010 motherboard line up, the other two on the left need to be repositioned.

I didn’t have to cut out as much as I originally thought!. The middle shelf needed to clear the 7010 motherboard by 2”, that leaves enough room to change the ram. There are still some alignment issues to deal with, mainly more filing on the bottom shelf modified PSU enclosure.

Finished off the PSU enclosure, filing down the edges didn’t take long at all. I can slide out the bottom shelf fairly easily after unscrewing the two screws that fasten it to the enclosure below. I cut out a gap above the PSU socket and switch for access. And surprisingly I was able to lift the whole thing and gently place it back in without damaging anything!. I also cleaned of the top shelf using a coarse metal sanding block. The finish reminds of when macOS used brushed metal effects for windows, was that before macOS went Aqua?.

Two Noctua NF-B9 redux-1600 arrived today, they were on sale at Newegg, $13 each. They’re connected to the 7010 mobo, via a Silverstone PWM fan splitter cable. With the new motherboard I’ll be able to attach up to 5 fans, more than enough. These are really quiet fans, much quieter than the Thermaltake with the blue LED I had previously installed. Temperatures are in the 30s while idle in Catalina.

Added 11-9.

Just wanted to report on temperatures inside the G5. For the past couple of days I haven't pushed the machine, I have run benchmarks and kept an eye on the temps. On my first G5 build I did lose a RX580, 16GB Ram and HP EX920 NVMe 256 GB, so you know!. The refurbished replacement graphics card, an RX 560, is currently holding at around 30 C. I have seen it dip to around 26 C in both windows and Catalina. Processor temperatures in both OS, hover around 35 C, I do need to replace the Thermal paste though. Adding the two Noctua fans has not only been good at keeping temps low. But also quietness!, I just hear a gentle whir and I'm sat next to it. I remember sitting next to an Original G5 in art college, it wasn't this quiet!.

The custom PSU enclosure I cut. The yellow circles show the two G5 processor bolts that screw into the the G5 psu enclosure. I drilled two 3mm holes into the bottom shelf, the right one is hidden by the rear fan guard. The left one is visible and I was limited to where I could put the screw. The white circle on the left is the original bottom shelf screw that screwed into the top of the psu, which I haven't used as it was heavy. The bottom two white circles show the standoffs that hold the heat shield. Access to the on/off switch is tight, I did cut a piece out, but it should be bigger. I assemble the PSU enclosure inside the case with the power cable plugged into PSU but not the mains.

I should note that the fan which sits on the middle shelf at the front, is a necessity. Whether it's original or not, if you're going to use the middle shelf there should be a fan in this area. It gets very hot around the PCI slots in the rear of the case, when gaming on the 7010 board.

Middle shelf.jpg



The fans I purchased for the G5 fan guards. When I install the H370M board I'll be able to plug in all the fans, and keep that 'Above the middle shelf area' much cooler. Also as I have just learnt, DO NOT attempt to attach all four fans via splitters to the one available fan connection on a Dell 7010. It's been pointed out before that I'm hard on my hardware by trs96. RX560 and RAM are in the post.

And the modified middle shelf. Originally you could attach the shelf to the G5 motherboard but that’s not possible with the 7010 or the H370 that will replace it. So I cut a 2” gap to clear the motherboard and allow access to ram. I didn’t use a Dremel, instead I used metal shears and a file to finish off the edges.

Hey, love the look of your build. Just started mine. Have my G5. Not sure what I am going to use parts wise. Mind if I copy yours? LOL. Are you up and running yet?
