Powermac G5 ATX mod – part 2: Case mod and motherboard fitting

Yes, I know… yet another G5 case mod… but, what can I do if the G5 case is SO amazing??? I bought a full G5 Powermac about an year ago at eBay for about 20 quid. The G5 wasn’t working and I didn’t intend to get it back to work, anyways. Just wanted the case. And the case was in perfect shape, no scratches or dents – very unusual, by the way… so, it would be a perfect fit to my project. I drove 2 hours round trip to get the case, and I left it in my garage for all this time. I knew this project would take me a great amount of time and patience, and I only wanted to start it when I was fully committed.

Well, with the lock-down, the time has come. I started by disassembling the whole thing – that, I should add – might be the most challenging bit of the project. Different than other Powermacs, the G5 was built in a very “locked” way, making it very challenging to fully disassembling it. But with time and a lot of Internet instructional videos, it’s doable of course. You have to make sure you don’t damage the chassis while disassembling the whole thing. So, again, take your time and don’t force anything out (like some people normally do).

Of course PC ATX (and variants) motherboards will not fit the case directly. Some modifications are needed to fit them properly. In my case, I choose a mATX board. I needed to cut the original mesh back plate of the G5 and also get the motherboard tray refitted. To obtain a greater finish, I choose the obvious option: Laser Hive G5 mATX original kit. It costed me £60, but it is totally worth it. You can see below the finished cut (I used a generic dremel with metal cutting discs and was able to finish the job in around 15 min).

And, here, the finished back panel, with the motherboard and video card already fitted. I still haven’t finished the project, as I need to buy the CPU, memory and Disk (I will go for a 1 TB M.2 SSD, which saves up the mess with cables and it is way faster than regular SSDs). I also still need to mod the from power button and USB, but I don’t think this will be too hard to do. Once all is done, I will post some pictures of the finished G5 atx here.


Refurbishing a PowerMac 6100/60 – final steps and showcase

To give you some perspective, below you can see the pictures of the before and after. Then, you can follow up watching the videos. Enjoy!

In the previous video, you see that there seems to be an issue when powering up the 6100. Basically, upon first power on, it didn’t display any image and didn’t do anything. Just halted. If I powered it down and up again, it then booted, but right after it start loading the extensions, it rebooted by itself and, only then, it proceeded to a full successful boot. Of course I wasn’t happy with this situation, and I was suspecting the lack of a CMOS battery could be the cause of this. So, I ordered a new 3.6v 1/2AA battery from Amazon and installed it as soon as it arrived, yesterday. Not surprisingly, the Mac started working as expected upon first boot try.

You can check this out in the below video.

External Macintosh M0130 floppy drive repair and clean up

In this video I show an attempt to repair an external Macintosh M0130 floppy drive I bought at eBay for £30. Seller sold this as for parts or not working as he said he was unable to test it – not unusual, as you would need a very old Macintosh to plug this in.

My hope was that the drive would be fully functional upon arrival, but for my disappointment, it wasn’t. Floppy disks wouldn’t get into the drive easily (I had to push them hard to get them in), and it wouldn’t eject the inserted disks afterwards. Needless to say it wasn’t reading the disks either.

So, I was determined to attempt a refurbish to this drive, as I do have a spare internal floppy removed from a non-working Mac SE that I thought it could work as a donor to this project. In the end, I didn’t have to try the “transplant” as the old drive did work after some hard cleaning and lubing works.
