Hello I am new here and don't really know much about this stuff. I have a macbook for school, but now that I'm home I want to turn my desktop into a mac since it's really slow and crappy now, and all the files I need I have saved on my external harddrive.

I don't want to dual boot, I want just mac on my pc. The computer's specs are:

eMachines T6520 Media Center PC specs and Desktop specifications - CNET Reviews

I tried two different ones including the iATKOS and Lawless PPC Leopard 10.5.4 Phenom & AMD but neither worked.

I currently have windows on the machine, but want to erase it completely and make it a full mac but no idea where to start.

Thanks in advance.
