    My iMac has had to have a clean OS install 5 times in the last 10 months.

    I finally convinced phone support it needed to go into the store for hardware checks.

    Logic board, RAM and HDD were replaced.

    When I received the machine back and got home, Apple had forgot to actually install the RAM alongside blue engineering tape still being present on the machine - great start.

    When checking the drive as well, I couldn't fully work out if a regular SATA disk had been installed or if its set up as a fusion drive with the flash. Is there anyway of telling? I ran some terminal lines which seemed to suggest it wasn't set up as one. Attached a few images.

    Any thoughts would be much appreciated before I end up back in the store tomorrow. What a nightmare its been owning this machine (second one as the first one melted the RAM modules).

    You do not have a Fusion drive setup there. You would have been able to see it with that "diskutil cs list" command.

    Here is what my fusion drive looks like under storage in the system report.

    What kind of speeds are you getting? Is the system responsive?
