Hi y'all. I was gifted a Mac Pro by my brother in law recently and am wondering what the best thing to do with it is. It's a Mac Pro Xeon 64-bit workstation. As best as I can tell it is a 2006-2008 "Quad core" 2.66. The model No. is A1186 and EMC No. 2113. It currently does not have any modifications to it. If I do upgrade it I'm not gonna need a crazy amount of power on it. I would probably at most just use it for gaming, running some CAD software, and in the future possibly digital testing of parts. I also would like it to have a current OS on it and just for ease of the programs I want to use would probably try to switch it over to windows. Any advice would be appreciated. Thanks.
