I am ready to purchase a new Mac Mini and thought I would like to replace the stock hard drive with an SSD. I consider myself a fairly handy guy, but after reading some of the horror stories here, of broken cables, etc, I am reconsidering this. Wondering if it would be feasible to put my OS and applications on an external SSD in a thunderbolt case. What would be the pros and cons of this? Any help would be appreciated.
