Hi All, I was wondering if anyone could help me out here. Anyone know where I can buy an inexpensive external thunderbolt HD enclosure... I'm looking to upgrade a family member's 2011 iMac and a family friend's 2011 Mac Mini to an SSD, but I don't want to open either up at the risk of breaking someone else's computer (If it was my own I'd probably do it ). So I want to buy a 128GB (inexpensive) SSD and put it into an also cheap external enclosure to use as the boot drive. However I can't seem to find an empty external thunderbolt enclosure, other than hugely expensive multi disk ones. Do these things exist at all?
