I just bought a 2006 model iMac 17'' for $150. My current plan is to find a newer model (2010 or newer) shell and transfer all the goodies inside mine into it giving me a better display (i.e 24"- 27"). I've found several people selling these shells (just the screen with nothing else inside) and am interested in doing it, but I need some guidance as to how practical (and/or difficult) this will be or if it is even possible at all. I talked to a guy at a computer repair shop, and he said that he would put it together for me for $130. Is this just going to result in my Mac being unusable and all my money gone? Oh, and I'm also wanting to upgrade the CPU to the core 2 duo and I'm not sure which is the best possible one I can get that will still be compatible. Thanks for any input.
