Ok this is my powermac 9500 that I have trashed due to me getting a Yosemite. It was good, for about 5 minutes after I got it, then I had to mod it. This is what I came up With. For starters I upgraded to abotu 700mb of ram, added a g3 266 upgrade card, and a usb card. I ran OS X on it for a while using X Post Facto, but then I relised how slow it is, thats why I trashed it, not to mention it was 7.5 years old at the time too.
And yes, I did take out the usful stuff like the cold cathode and led fan before i got trid of it.
