Hello, this is my first post here. My family we have all MacMinis (mid 2007) Core 2 Duo (bought them at once so nobody is jealous), running Lion with 2GB, and I am thinking of upgrading them with ~120GB SSD. I guess that the 6G models (SATA-3) would be an utter waste, so the models left are "Mercury EXTREME Pro 3G", "Intel 320", maybe OCZ. Or maybe not, and 6G models are worth considering. Any informed opinion would be most helpful. Thanks!
