just wondering here........i have a emachines t3642 PC that runs Windows Vista Home Premium and i was wanting to know if i would be able to turn it into a Mac??....i know i would probably have to install a new motherboard and put in a new hard drive and probably a new CPU that runs Mac but i have some extra ddr3 memory modules laying around, can i use those with Mac or is there different ones for Mac??.....i know, im probably better off buying a Mac but i already have an extra motherboard and memory laying around and i thought it might be fun to see if i could turn my PC into a Mac.......and i know the Mac OS is alot cheaper than Windows.
