I recently bought a Mac Pro 1,1 and factory reset it, as it had someones data on it. When I go to reinstall Mac OS Lion (10.7) it errors saying ‘This item is unavailable’ and research has told me this is because it was linked to the previous owners Apple ID. So I bought a Snow Leopard CD (10.6.3) but it says my Mac is not supported. There is currently no OS just the recovery drive from Lion. I currently have a Nvidia Quadro NVS 295 inside as well as the 7300GT, with 6GB of RAM. Is there any way to get a Mac OS version or Windows on the machine? The fans are also at full speed all the time, is there any way to fix this?
