I want to make an external SSD boot drive that will be backward compatible with my old mini (FW800 is it's fastest port), so I'm looking for an enclosure that supports FW800 and USB 3.0. So far I've found the OWC Elite Pro Mini (£50 with shipping to UK) or an Icy Box (also £50 on Amazon). This is pretty steep for an enclosure but I appreciate I'm trying to buy something niche and somewhat obsolete. Which would you choose? Or could you recommend a third option?
