I'm currently working on a G5 mod which I want to keep as clean as possible. Now I want to reuse the G5 PSU housing and I have already taken out the guts of my PSU which I'm going to put in there. Physically it fits but right now it's just laying there not attached to anything so I wanted to ask here about tips for me when I attach the PSU to the casing.

What's the best way to do it?
What should I do and what shouldn't I do?
Have any of you run into any problems? How did you fix them? If not how did you do your mod?

All opinions and voices about mounting a PSU into the G5 PSU housing is interesting.

The easiest way I have found to do this is using 3M High Bond Outdoor Double Sided Foam tape. I use two strips right up against the PCB. Then to that I attach a cut piece of that plastic thing that sat underneath the G5 power supply so that there is no chance of a jump between a trace and the chassis. Then another two strips of tape to hold the whole thing to the bottom of the PSU chassis. I've done two like this and they are still holding strong. Hope that helps. Take care. Dan.

I had some thick aluminium tube that I used to make stand-offs to use the holes in the PCB. I used a countersunk bolt from the bottom of the old PSU case, thru the stand-off, thru the PCB and a small washer & nut on top. In addition, I used the rigid plastic film (I think from the apple PSU) to create an insulation barrier between the PCB and the base of the PSU. If you're going to use adhesive tape, remember temperatures can get pretty high inside the PSU.

I wanted my Hackintosh (code named Power Mac G7) to be as clean as possible, too. What I did for my PSU was make a mounting plate out of Plexiglass and fit it into the bottom of the PSU case after it was stripped out.

I used the PSU plastic liner that was underneath the G5 Power supply as a template to make the respective "mounting plate" for my PSU out of the plexiglass.

As you can see, I drilled the respective holes. On some of them (and if you do this I recommend this tip), you'll notice some of the drilled holes are broken on one side. This was from my personal mistake of drilling the plexiglass with too high of a torque on my power drill. BE VERY CAREFUL and delicate when using plexiglass.

Mounting plate is screwed into the original screw brackets and attached with PSU in place.

Finished product with my own added touch. Except for those little "additions," I did as minimal "redesigning" to the PSU case as possible. It worked out awesomely and my PSU is chugging right along!

If you have any more questions on how I did the entire process, I'd be glad to elaborate. I'll probably post one of my own "HERE'S MY G5" threads here soon.

Check out the link to my build.

I used a Thermaltake 850w modular PSU. What I did was pull it apart and cut the bottom of the Thermaltake PSU and kept it screwed to itself and then I hot glued that to the bottom of the G5's bare PSU. I used hot glue because if I needed to remove the Thermaltake PSU I can still pry it out and remove the glue from both metals with no residue. I also stored all of my extra cables in the spare space inside the G5's PSU housing and mounted the Thermaltake cooling fan on top of the whole unit with the modular panel next to it.
