So I take it this mod can only be done on windows? Well if that is the case Windows WINS!!! Ooops did I say that out load Having said that There's a lot of software on the Mac that I like and use all the time. With that in mind the idea of a Linux box was only to run stuff like Maya and the likes. Lightwave, Shake, Photoshop & Final cut I will stick with Mac and all the rest go with Windows. OK so thats my OS sorted, Hard drives, and graphic card dealt with, all I need now is which CPU and Which Motherboard? I can't say enough how much I appreciate this help, I hope someday I'll be able to repay you all Cheers Chris
