Right now I have a 2011 iMac, 1TB HD and I might get the 2013 Pro Mac when it's available. So I thinking that I would have a 3TB hard drive and a 240GB SSD HD installed in my iMac. The SSD would be for the OS. I would use my iMac monitor for the 2013 Pro Mac using target mode with Thunder Bolt. I would also use the iMac as sample library slave using Vienna Ensemble Pro 5 over the ethernet connection. Does this sound like it would work? I'm sure the 2013 Pro Mac will have TB ports.
