[Herb Sevush] “If the system case isn’t designed to be opened and worked on by a skilled amateur”
Well, current mac minis and macbooks pro are designed to be opened and worked on by a skilled amateur!
And you can clone your internal drive to a firewire/usb/thunderbolt drive and work from
there if the internal drive fails.
I have all of my work data on external raid drives and time machine backups
of emails, address book, calendar and other documents.
if you have a spare mini your up and running in minutes.
