So, before I move forward with my plan here, I was curious on something. There are a ton of threads about adding a monitor to an iMac, or hooking things like a PC / Xbox to an iMac display, but is there any reason you couldn't stick 2 iMacs together? I currently have an '09 i5 27" which I wish to keep, but I want to grab one of the new 27" '10 i7's to replace it as my primary system. The ultimate goal would be to run them both with the new i7 being the primary and the old i5 being a secondary display + passive file server / windows machine as needed. Can anybody see any issue with doing this? It isn't really documented anywhere nor have I seen this done. I know it requires a specific cable, such as: http://www.belkin.com/IWCatProductPage.process?Product_Id=508255 Can anybody who has maybe tried this confirm if it works?
