Just bought a 27 imac got a good deal IMO. It comes with a 1 Regular tb hdd. What I'd like to do is get a external ssd for boot to speed it up. What are some suggested ssds for this? It'd be through tb. Also because my son likes to game I'd like to get windows 7 on it thru bootcamp as well. Any way to have all of it on the ssd, while having the 1 tb for files/media?
