I already have 3 SSDs floating around that I know are good (Samsung 840 Pro). I wouldn't want to kick out for another 256Gb SSD when I already have one. Not only that, those fusion drives are terribly unreliable from experience.

Regardless of that, that process is HELL compared to another machine. The thing I'm typing this on now (Lenovo T400) requires any old screwdriver you have lying around and 2 mins.

1960s point to point wired televisions are easier to repair.
